By engaging with VMware, the business has strengthened its network security and addressed business continuity concerns. Today, Helvetia is more automated, more efficient and better able to focus on new business opportunities.\r\nOver 160 years, Helvetia Insurance has grown into a successful, international insurance group. With headquarters in St. Gallen and Basel, it is Switzerland's leading all-lines insurer. Helvetia’s success is founded on the diversification between life and non-life business, and as well as a strong home market, it has profitable market positions in other European countries, with above-average growth in Germany, Austria, Italy and Spain. In the Specialty Markets segment, Helvetia offers bespoke specialty lines cover and reinsurance solutions in selected niches worldwide. It provides its five million plus customer-base with professional advice on all insurance matters, as well as contacts for various sectors under a single roof. More than 7,500 employees work daily to arrive at simple solutions.\r\nHelvetia’s brand promise, &quot;simple. clear. helvetia&quot; applies to customers, shareholders and employees alike. The insurance sector is perceived as complicated. Helvetia wants to make the world of insurance simple to access and easier to understand.\r\n<span style=\"font-weight: bold;\">Challenge</span>\r\nHelvetia is one of Switzerland’s largest insurance providers. It is also an increasingly international business. It already has operations across Europe and plans for further growth.\r\nStaying still is not an option. Increased competition from new entrants, digital services, and data revolution have created a compelling case for digital transformation in the insurance sector. If traditional insurers expect to remain competitive, they must become more agile, more efficient, more customer-centric, and more sophisticated in the way they use data and analytics. These qualities are reflected in Helvetia’s ‘20.20’ growth strategy. The business wants digital transformation to make customer services faster, easier and more personal. Achieving high customer satisfaction and trust is one of Helvetia’s primary goals.\r\nThe company is committed to delivering high quality, secure services for customers and its employees. Having a secure IT environment is a critical part of Helvetia’s operations.\r\n<span style=\"font-style: italic;\">“The insurance business is based on trust,” says Andreas Hagin, Lead Engineer, IT Infrastructure, Helvetia. “Focusing on customers is firmly anchored in our values and we set very high standards for ourselves and our IT security.”</span>\r\nFor Helvetia IT, one challenge is being able to handle a rapidly growing volume of work with the same number of employees. That means minimizing the number of manual tasks required of team members, reducing the need to retrain and redeploy teams, and finding new ways to deliver services as efficiently as possible.\r\nDigesting the 2014 acquisition of rivals Nationale Suisse provided an ideal opportunity for the company to rethink its IT approach. The acquisition required the consolidation of four data centers into two. <span style=\"font-style: italic;\">“We didn’t have enough space to consolidate into two, so we started to look for new premises in Switzerland,” says Hagin. “We started with a blank sheet of paper.”</span>\r\n<span style=\"font-weight: bold;\">Action</span>\r\nHelvetia’s virtualization journey began with VMware in 2003. Hagin saw the consolidation project as the right time to start micro-segmentation of its data centers:<span style=\"font-style: italic;\"> “Security is becoming more and more important. Micro-segmentation means we have better control of our servers. This is key in the insurance market.”</span>\r\nThe VMware solution, part of the Enterprise Level Agreement, is based on VMware NSX® Data Center. This helps create a Software-Defined Data Center (SDDC) for Helvetia, delivering networking and security entirely in software, abstracted from the underlying physical infrastructure, as well as increased functionality.\r\nIn addition, VMware vCloud Suite® is an enterprise-ready hybrid cloud software that brings together the industry-leading VMware vSphere® Hypervisor 6.0 and 6.5, VMware vRealize® Suite cloud management platform and VMware vRealize® Network Insight™. vRealize Suite provides developer-friendly infrastructure (supporting VMs and containers) and a common approach to hybrid and multicloud and works together with NSX to dramatically reduce the delivery time of VMs.","alias":"vmware-nsx-data-center-for-a-globally-active-swiss-insurance-group","roi":0,"seo":{"title":"VMware NSX Data Center for a globally active Swiss insurance group","keywords":"","description":"<span style=\"font-weight: bold;\">KEY CHALLENGES</span>\r\n• Enable the business to be faster to market with new, digital services\r\n• Improve IT efficiency with simplified management and greater automation\r\n• Consolidate four data centers into two\r\n<span style=\"f","og:title":"VMware NSX Data Center for a globally active Swiss insurance group","og:description":"<span style=\"font-weight: bold;\">KEY CHALLENGES</span>\r\n• Enable the business to be faster to market with new, digital services\r\n• Improve IT efficiency with simplified management and greater automation\r\n• Consolidate four data centers into two\r\n<span style=\"f"},"deal_info":"","user":{"id":4746,"title":"Helvetia","logoURL":"https://old.roi4cio.com/uploads/roi/company/Helvetia.jpg","alias":"helvetia","address":"","roles":[],"description":"Helvetia is a globally active Swiss insurance group.

To fully grasp how VMs work, it’s important to first understand how computer software and hardware are typically integrated by an operating system.\r\n&quot;The cloud&quot; refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies don't have to manage physical servers themselves or run software applications on their own machines.\r\nThe cloud enables users to access the same files and applications from almost any device, because the computing and storage take place on servers in a data center, instead of locally on the user device. This is why a user can log into their Instagram account on a new phone after their old phone breaks and still find their old account in place, with all their photos, videos, and conversation history. It works the same way with cloud email providers like Gmail or Microsoft Office 365, and with cloud storage providers like Dropbox or Google Drive.\r\nFor businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact on small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access the same files and applications from any location.\r\nSeveral cloud providers offer virtual machines to their customers. These virtual machines typically live on powerful servers that can act as a host to multiple VMs and can be used for a variety of reasons that wouldn’t be practical with a locally-hosted VM. These include:\r\n<ul><li>Running SaaS applications - Software-as-a-Service, or SaaS for short, is a cloud-based method of providing software to users. SaaS users subscribe to an application rather than purchasing it once and installing it. These applications are generally served to the user over the Internet. Often, it is virtual machines in the cloud that are doing the computation for SaaS applications as well as delivering them to users. If the cloud provider has a geographically distributed network edge, then the application will run closer to the user, resulting in faster performance.</li><li>Backing up data - Cloud-based VM services are very popular for backing up data because the data can be accessed from anywhere. Plus, cloud VMs provide better redundancy, require less maintenance, and generally scale better than physical data centers. (For example, it’s generally fairly easy to buy an extra gigabyte of storage space from a cloud VM provider, but much more difficult to build a new local data server for that extra gigabyte of data.)</li><li>Hosting services like email and access management - Hosting these services on cloud VMs is generally faster and more cost-effective, and helps minimize maintenance and offload security concerns as well.</li></ul>","materialsDescription":"What is an operating system?\r\nTraditional computers are built out of physical hardware, including hard disk drives, processor chips, RAM, etc. In order to utilize this hardware, computers rely on a type of software known as an operating system (OS). Some common examples of OSes are Mac OSX, Microsoft Windows, Linux, and Android.\r\nThe OS is what manages the computer’s hardware in ways that are useful to the user. For example, if the user wants to access the Internet, the OS directs the network interface card to make the connection. If the user wants to download a file, the OS will partition space on the hard drive for that file. The OS also runs and manages other pieces of software. For example, it can run a web browser and provide the browser with enough random access memory (RAM) to operate smoothly. Typically, operating systems exist within a physical computer at a one-to-one ratio; for each machine, there is a single OS managing its physical resources.\r\n<span style=\"font-weight: bold;\">Can you have two or more operating systems on one computer?</span>\r\nSome users want to be able to run multiple operating systems simultaneously on one computer, either for testing or one of the other reasons listed in the section below. This can be achieved through a process called virtualization. In virtualization, a piece of software behaves as if it were an independent computer. This piece of software is called a virtual machine, also known as a ‘guest’ computer. (The computer on which the VM is running is called the ‘host’.) The guest has an OS as well as its own virtual hardware.\r\n‘Virtual hardware’ may sound like a bit of an oxymoron, but it works by mapping to real hardware on the host computer. For example, the VM’s ‘hard drive’ is really just a file on the host computer’s hard drive. When the VM wants to save a new file, it actually has to communicate with the host OS, which will write this file to the host hard drive. Because virtual hardware must perform this added step of negotiating with the host to access hardware resources, virtual machines can’t run quite as fast as their host computers.\r\nWith virtualization, one computer can run two or more operating systems. The number of VMs that can run on one host is limited only by the host’s available resources. The user can run the OS of a VM in a window like any other program, or they can run it in fullscreen so that it looks and feels like a genuine host OS.\r\n <span style=\"font-weight: bold; \">What are virtual machines used for?</span>\r\nSome of the most popular reasons people run virtual machines include:\r\n<span style=\"font-weight: bold; \">Testing</span> - Oftentimes software developers want to be able to test their applications in different environments. They can use virtual machines to run their applications in various OSes on one computer. This is simpler and more cost-effective than having to test on several different physical machines.\r\n<span style=\"font-weight: bold; \">Running software designed for other OSes</span> - Although certain software applications are only available for a single platform, a VM can run software designed for a different OS. For example, a Mac user who wants to run software designed for Windows can run a Windows VM on their Mac host.\r\n<span style=\"font-weight: bold; \">Running outdated software</span> - Some pieces of older software can’t be run in modern OSes. Users who want to run these applications can run an old OS on a virtual machine.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Virtual_machine_and_cloud_system_software.png"},{"id":1,"title":"Desktop virtualization","alias":"desktop-virtualization","description":" Desktop virtualization is a virtualization technology that separates an individual's PC applications from his or her desktop. Virtualized desktops are generally hosted on a remote central server, rather than the hard drive of the personal computer. Because the client-server computing model is used in virtualizing desktops, desktop virtualization is also known as client virtualization.\r\nDesktop virtualization provides a way for users to maintain their individual desktops on a single, central server. The users may be connected to the central server through a LAN, WAN or over the Internet.\r\nDesktop virtualization has many benefits, including a lower total cost of ownership (TCO), increased security, reduced energy costs, reduced downtime and centralized management.\r\nLimitations of desktop virtualization include difficulty in maintenance and set up of printer drivers; increased downtime in case of network failures; complexity and costs involved in VDI deployment and security risks in the event of improper network management.<br /><br />","materialsDescription":" <span style=\"font-weight: bold; \">What are types of desktop virtualization technologies?</span>\r\nHost-based forms of desktop virtualization require that users view and interact with their virtual desktops over a network by using a remote display protocol. Because processing takes place in a data center, client devices can be traditional PCs, but also thin clients, zero clients, smartphones and tablets. Examples of host-based desktop virtualization technology include:\r\n<span style=\"font-weight: bold; \">Host-based virtual machines:</span> Each user connects to an individual VM that is hosted in a data center. The user may connect to the same VM every time, allowing for personalization (known as a persistent desktop), or be given a fresh VM at each login (a nonpersistent desktop).\r\n<span style=\"font-weight: bold; \">Shared hosted:</span> Users connect to a shared desktop that runs on a server. Microsoft Remote Desktop Services, formerly Terminal Services, takes this client-server approach. Users may also connect to individual applications running on a server; this technology is an example of application virtualization.\r\n<span style=\"font-weight: bold; \">Host-based physical machines:</span> The operating system runs directly on another device's physical hardware.\r\nClient virtualization requires processing to occur on local hardware; the use of thin clients, zero clients and mobile devices is not possible. These types of desktop virtualization include:\r\n<span style=\"font-weight: bold; \">OS image streaming:</span> The operating system runs on local hardware, but it boots to a remote disk image across the network. This is useful for groups of desktops that use the same disk image. OS image streaming, also known as remote desktop virtualization, requires a constant network connection in order to function.\r\n<span style=\"font-weight: bold; \">Client-based virtual machines:</span> A VM runs on a fully functional PC, with a hypervisor in place. Client-based virtual machines can be managed by regularly syncing the disk image with a server, but a constant network connection is not necessary in order for them to function.\r\n<span style=\"font-weight: bold;\">Desktop virtualization vs. virtual desktop infrastructure</span>\r\nThe terms <span style=\"font-style: italic;\">desktop virtualization</span> and virtual desktop infrastructure (VDI) are often used interchangeably, but they are not the same. While VDI is a type of desktop virtualization, not all desktop virtualization uses VDI.\r\nVDI refers to the use of host-based VMs to deliver virtual desktops, which emerged in 2006 as an alternative to Terminal Services and Citrix's client-server approach to desktop virtualization technology. Other types of desktop virtualization -- including the shared hosted model, host-based physical machines and all methods of client virtualization -- are not examples of VDI.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Desktop_virtualization.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":2517,"logo":false,"scheme":false,"title":"VMware NSX Data Center","vendorVerified":0,"rating":"2.40","implementationsCount":1,"suppliersCount":0,"alias":"vmware-nsx-data-center","companyTypes":[],"description":"VMware NSX® Data Center is the network virtualization and security platform that enables the virtual cloud network, a software-defined approach to networking that extends across data centers, clouds, and application frameworks.

ITSM is focused on aligning IT processes and services with business objectives to help an organization grow.\r\nITSM positions IT services as the key means of delivering and obtaining value, where an internal or external IT service provider works with business customers, at the same time taking responsibility for the associated costs and risks. ITSM works across the whole lifecycle of a service, from the original strategy, through design, transition and into live operation.\r\nTo ensure sustainable quality of IT services, ITSM establishes a set of practices, or processes, constituting a service management system. There are industrial, national and international standards for IT service management solutions, setting up requirements and good practices for the management system. \r\nITSM system is based on a set of principles, such as focusing on value and continual improvement. It is not just a set of processes – it is a cultural mindset to ensure that the desired outcome for the business is achieved. \r\n<span style=\"font-weight: bold; \">ITIL (IT Infrastructure Library)</span> is a framework of best practices and recommendations for managing an organization's IT operations and services. IT service management processes, when built based on the ITIL framework, pave the way for better IT service operations management and improved business. To summarize, ITIL is a set of guidelines for effective IT service management best practices. ITIL has evolved beyond the delivery of services to providing end-to-end value delivery. The focus is now on the co-creation of value through service relationships. \r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">ITSM processes typically include five stages, all based on the ITIL framework:</span></p>\r\n<span style=\"font-weight: bold; \">ITSM strategy.</span> This stage forms the foundation or the framework of an organization's ITSM process building. It involves defining the services that the organization will offer, strategically planning processes, and recognizing and developing the required assets to keep processes moving. \r\n<span style=\"font-weight: bold; \">Service design.</span> This stage's main aim is planning and designing the IT services the organization offers to meet business demands. It involves creating and designing new services as well as assessing current services and making relevant improvements.\r\n<span style=\"font-weight: bold; \">Service transition.</span> Once the designs for IT services and their processes have been finalized, it's important to build them and test them out to ensure that processes flow. IT teams need to ensure that the designs don't disrupt services in any way, especially when existing IT service processes are upgraded or redesigned. This calls for change management, evaluation, and risk management. \r\n<span style=\"font-weight: bold; \">Service operation. </span>This phase involves implementing the tried and tested new or modified designs in a live environment. While in this stage, the processes have already been tested and the issues fixed, but new processes are bound to have hiccups—especially when customers start using the services. \r\n<span style=\"font-weight: bold;\">Continual service improvement (CSI).</span> Implementing IT processes successfully shouldn't be the final stage in any organization. There's always room for improvement and new development based on issues that pop up, customer needs and demands, and user feedback.\r\n\r\n","materialsDescription":"<h1 class=\"align-center\">Benefits of efficient ITSM processes</h1>\r\nIrrespective of the size of business, every organization is involved in IT service management in some way. ITSM ensures that incidents, service requests, problems, changes, and IT assets—in addition to other aspects of IT services—are managed in a streamlined way.\r\nIT teams in your organization can employ various workflows and best practices in ITSM, as outlined in ITIL. Effective IT service management can have positive effects on an IT organization's overall function.\r\nHere are the 10 key benefits of ITSM:\r\n<ul><li>&nbsp;&nbsp;&nbsp; Lower costs for IT operations</li><li>&nbsp;&nbsp;&nbsp; Higher returns on IT investments</li><li>&nbsp;&nbsp;&nbsp; Minimal service outages</li><li>&nbsp;&nbsp;&nbsp; Ability to establish well-defined, repeatable, and manageable IT processes</li><li>&nbsp;&nbsp;&nbsp; Efficient analysis of IT problems to reduce repeat incidents</li><li>&nbsp;&nbsp;&nbsp; Improved efficiency of IT help desk teams</li><li>&nbsp;&nbsp;&nbsp; Well-defined roles and responsibilities</li><li>&nbsp;&nbsp;&nbsp; Clear expectations on service levels and service availability</li><li>&nbsp;&nbsp;&nbsp; Risk-free implementation of IT changes</li><li>&nbsp;&nbsp;&nbsp; Better transparency into IT processes and services</li></ul>\r\n<h1 class=\"align-center\">How to choose an ITSM tool?</h1>\r\nWith a competent IT service management goal in mind, it's important to invest in a service desk solution that caters to your business needs. It goes without saying, with more than 150 service desk tools to choose from, selecting the right one is easier said than done. Here are a few things to keep in mind when choosing an ITSM products:\r\n<span style=\"font-weight: bold; \">Identify key processes and their dependencies. </span>Based on business goals, decide which key ITSM processes need to be implemented and chart out the integrations that need to be established to achieve those goals. \r\n<span style=\"font-weight: bold; \">Consult with ITSM experts.</span> Participate in business expos, webinars, demos, etc., and educate yourself about the various options that are available in the market. Reports from expert analysts such as Gartner and Forrester are particularly useful as they include reviews of almost every solution, ranked based on multiple criteria.\r\n<span style=\"font-weight: bold; \">Choose a deployment option.</span> Every business has a different IT infrastructure model. Selecting an on-premises or software as a service (SaaS IT service management) tool depends on whether your business prefers to host its applications and data on its own servers or use a public or private cloud.\r\n<span style=\"font-weight: bold; \">Plan ahead for the future.</span> Although it's important to consider the &quot;needs&quot; primarily, you shouldn't rule out the secondary or luxury capabilities. If the ITSM tool doesn't have the potential to adapt to your needs as your organization grows, it can pull you back from progressing. Draw a clear picture of where your business is headed and choose an service ITSM that is flexible and technology-driven.\r\n<span style=\"font-weight: bold;\">Don't stop with the capabilities of the ITSM tool.</span> It might be tempting to assess an ITSM tool based on its capabilities and features but it's important to evaluate the vendor of the tool. A good IT support team, and a vendor that is endorsed for their customer-vendor relationship can take your IT services far.

SaaS software solutions has become a common delivery model for many business applications, including office software, messaging software, payroll processing software, DBMS software, management software, CAD software, development software, gamification, virtualization, accounting, collaboration, customer relationship management (CRM), Management Information Systems (MIS), enterprise resource planning (ERP), invoicing, human resource management (HRM), talent acquisition, learning management systems, content management (CM), Geographic Information Systems (GIS), and service desk management. SaaS has been incorporated into the strategy of nearly all leading enterprise software companies.\r\nSaaS applications are also known as <span style=\"font-weight: bold;\">Web-based software</span>, <span style=\"font-weight: bold;\">on-demand software</span> and<span style=\"font-weight: bold;\"> hosted software</span>.\r\nThe term &quot;Software as a Service&quot; (SaaS) is considered to be part of the nomenclature of cloud computing, along with Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Desktop as a Service (DaaS),managed software as a service (MSaaS), mobile backend as a service (MBaaS), and information technology management as a service (ITMaaS).\r\nBecause SaaS is based on cloud computing it saves organizations from installing and running applications on their own systems. That eliminates or at least reduces the associated costs of hardware purchases and maintenance and of software and support. The initial setup cost for a SaaS application is also generally lower than it for equivalent enterprise software purchased via a site license.\r\nSometimes, the use of SaaS cloud software can also reduce the long-term costs of software licensing, though that depends on the pricing model for the individual SaaS offering and the enterprise’s usage patterns. In fact, it’s possible for SaaS to cost more than traditional software licenses. This is an area IT organizations should explore carefully.<br />SaaS also provides enterprises the flexibility inherent with cloud services: they can subscribe to a SaaS offering as needed rather than having to buy software licenses and install the software on a variety of computers. The savings can be substantial in the case of applications that require new hardware purchases to support the software.<br /><br /><br /><br />","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: normal;\">Who uses SaaS?</span></h1>\r\nIndustry analyst Forrester Research notes that SaaS adoption has so far been concentrated mostly in human resource management (HRM), customer relationship management (CRM), collaboration software (e.g., email), and procurement solutions, but is poised to widen. Today it’s possible to have a data warehouse in the cloud that you can access with business intelligence software running as a service and connect to your cloud-based ERP like NetSuite or Microsoft Dynamics.The dollar savings can run into the millions. And SaaS installations are often installed and working in a fraction of the time of on-premises deployments—some can be ready in hours. \r\nSales and marketing people are likely familiar with Salesforce.com, the leading SaaS CRM software, with millions of users across more than 100,000 customers. Sales is going SaaS too, with apps available to support sales in order management, compensation, quote production and configure, price, quoting, electronic signatures, contract management and more.\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">Why SaaS? Benefits of software as a service</span></h1>\r\n<ul><li><span style=\"font-weight: bold;\">Lower cost of entry</span>. With SaaS solution, you pay for what you need, without having to buy hardware to host your new applications. Instead of provisioning internal resources to install the software, the vendor provides APIs and performs much of the work to get their software working for you. The time to a working solution can drop from months in the traditional model to weeks, days or hours with the SaaS model. In some businesses, IT wants nothing to do with installing and running a sales app. In the case of funding software and its implementation, this can be a make-or-break issue for the sales and marketing budget, so the lower cost really makes the difference.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Reduced time to benefit/rapid prototyping</span>. In the SaaS model, the software application is already installed and configured. Users can provision the server for the cloud and quickly have the application ready for use. This cuts the time to benefit and allows for rapid demonstrations and prototyping. With many SaaS companies offering free trials, this means a painless proof of concept and discovery phase to prove the benefit to the organization. </li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Pay as you go</span>. SaaS business software gives you the benefit of predictable costs both for the subscription and to some extent, the administration. Even as you scale, you can have a clear idea of what your costs will be. This allows for much more accurate budgeting, especially as compared to the costs of internal IT to manage upgrades and address issues for an owned instance.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">The SaaS vendor is responsible for upgrades, uptime and security</span>. Under the SaaS model, since the software is hosted by the vendor, they take on the responsibility for maintaining the software and upgrading it, ensuring that it is reliable and meeting agreed-upon service level agreements, and keeping the application and its data secure.&nbsp; While some IT people worry about Software as a Service security outside of the enterprise walls, the likely truth is that the vendor has a much higher level of security than the enterprise itself would provide. Many will have redundant instances in very secure data centers in multiple geographies.&nbsp; Also, the data is being automatically backed up by the vendor, providing additional security and peace of mind. Because of the data center hosting, you’re getting the added benefit of at least some disaster recovery. Lastly, the vendor manages these issues as part of their core competencies—let them.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Integration and scalability.</span> Most SaaS apps are designed to support some amount of customization for the way you do business. SaaS vendors create APIs to allow connections not only to internal applications like ERPs or CRMs but also to other SaaS providers. One of the terrific aspects of integration is that orders written in the field can be automatically sent to the ERP. Now a salesperson in the field can check inventory through the catalog, write the order in front of the customer for approval, send it and receive confirmation, all in minutes. And as you scale with a SaaS vendor, there’s no need to invest in server capacity and software licenses. </li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Work anywhere</span>. Since the software is hosted in the cloud and accessible over the internet, users can access it via mobile devices wherever they are connected. This includes checking customer order histories prior to a sales call, as well as having access to real time data and real time order taking with the customer.</li></ul>\r\n<p class=\"align-left\">&nbsp;</p>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/SaaS__1_.png"},{"id":299,"title":"Application and User Session Virtualization","alias":"application-and-user-session-virtualization","description":"Application virtualization is a technology that allows you to separate the software from the operating system on which it operates. Fully virtualized software is not installed in the traditional sense, although the end-user at first glance can not see it, because the virtualized software works just as normal. The software in the execution process works just as if it interacted with the operating system directly and with all its resources, but can be isolated or executed in a sandbox with different levels of restriction.\r\nModern operating systems, such as Microsoft Windows and Linux, can include limited software virtualization. For example, Windows 7 has Windows XP mode that allows you to run Windows XP software on Windows 7 without any changes.\r\nUser session virtualization is a newer version of desktop virtualization that works at the operating system level. While normal virtualization of the desktop allows an operating system to be run by virtualizing the hardware of the desktop, RDS and App-V allow for the virtualization of the applications. User session virtualization lies between the two.\r\nA desktop has an operating system loaded on the base hardware. This can be either physical or virtual. The user session virtualization keeps track of all changes to the operating system that a user might make by encapsulating the configuration changes and associating them to the user account. This allows the specific changes to be applied to the underlying operating system without actually changing it. This allows several users to have completely different operating system configurations applied to base operating system installation.\r\nIf you are in a distributed desktop environment and there are local file servers available at each location, you can deploy virtualized user sessions in the form of redirected folders and roaming profiles.","materialsDescription":" <span style=\"font-weight: bold;\">Understanding application virtualization</span>\r\nApplication virtualization technology isolates applications from the underlying operating system and from other applications to increase compatibility and manageability. This application virtualization technology enables applications to be streamed from a centralized location into an isolation environment on the target device where they will execute. The application files, configuration, and settings are copied to the target device and the application execution at run time is controlled by the application virtualization layer. When executed, the application run time believes that it is interfacing directly with the operating system when, in fact, it is interfacing with a virtualization environment that proxies all requests to the operating system.\r\n<span style=\"font-weight: bold;\">Understanding session virtualization</span>\r\nSession virtualization uses application streaming to deliver applications to hosting servers in the datacenter. The Application then connects the user to the server. The application then executes entirely on the server. The user interacts with the application remotely by sending mouse-clicks and keystrokes to the server. The server then responds by sending screen updates back to the user’s device. Whereas application virtualization is limited to Windows-based operating systems, session virtualization allows any user on any operating system to access any application delivered by IT. As a result, the application enables Windows, Mac, Linux, iOS and Android devices to run any applications using session virtualization. Furthermore, session virtualization leverages server-side processing power which liberates IT from the endless cycle of PC hardware refreshes which are typically needed to support application upgrades when using traditional application deployment methods.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Application_and_User_Session_Virtualization__1_.png"},{"id":1,"title":"Desktop virtualization","alias":"desktop-virtualization","description":" Desktop virtualization is a virtualization technology that separates an individual's PC applications from his or her desktop. Virtualized desktops are generally hosted on a remote central server, rather than the hard drive of the personal computer. Because the client-server computing model is used in virtualizing desktops, desktop virtualization is also known as client virtualization.\r\nDesktop virtualization provides a way for users to maintain their individual desktops on a single, central server. The users may be connected to the central server through a LAN, WAN or over the Internet.\r\nDesktop virtualization has many benefits, including a lower total cost of ownership (TCO), increased security, reduced energy costs, reduced downtime and centralized management.\r\nLimitations of desktop virtualization include difficulty in maintenance and set up of printer drivers; increased downtime in case of network failures; complexity and costs involved in VDI deployment and security risks in the event of improper network management.<br /><br />","materialsDescription":" <span style=\"font-weight: bold; \">What are types of desktop virtualization technologies?</span>\r\nHost-based forms of desktop virtualization require that users view and interact with their virtual desktops over a network by using a remote display protocol. Because processing takes place in a data center, client devices can be traditional PCs, but also thin clients, zero clients, smartphones and tablets. Examples of host-based desktop virtualization technology include:\r\n<span style=\"font-weight: bold; \">Host-based virtual machines:</span> Each user connects to an individual VM that is hosted in a data center. The user may connect to the same VM every time, allowing for personalization (known as a persistent desktop), or be given a fresh VM at each login (a nonpersistent desktop).\r\n<span style=\"font-weight: bold; \">Shared hosted:</span> Users connect to a shared desktop that runs on a server. Microsoft Remote Desktop Services, formerly Terminal Services, takes this client-server approach. Users may also connect to individual applications running on a server; this technology is an example of application virtualization.\r\n<span style=\"font-weight: bold; \">Host-based physical machines:</span> The operating system runs directly on another device's physical hardware.\r\nClient virtualization requires processing to occur on local hardware; the use of thin clients, zero clients and mobile devices is not possible. These types of desktop virtualization include:\r\n<span style=\"font-weight: bold; \">OS image streaming:</span> The operating system runs on local hardware, but it boots to a remote disk image across the network. This is useful for groups of desktops that use the same disk image. OS image streaming, also known as remote desktop virtualization, requires a constant network connection in order to function.\r\n<span style=\"font-weight: bold; \">Client-based virtual machines:</span> A VM runs on a fully functional PC, with a hypervisor in place. Client-based virtual machines can be managed by regularly syncing the disk image with a server, but a constant network connection is not necessary in order for them to function.\r\n<span style=\"font-weight: bold;\">Desktop virtualization vs. virtual desktop infrastructure</span>\r\nThe terms <span style=\"font-style: italic;\">desktop virtualization</span> and virtual desktop infrastructure (VDI) are often used interchangeably, but they are not the same. While VDI is a type of desktop virtualization, not all desktop virtualization uses VDI.\r\nVDI refers to the use of host-based VMs to deliver virtual desktops, which emerged in 2006 as an alternative to Terminal Services and Citrix's client-server approach to desktop virtualization technology. Other types of desktop virtualization -- including the shared hosted model, host-based physical machines and all methods of client virtualization -- are not examples of VDI.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Desktop_virtualization.png"},{"id":4,"title":"Data center","alias":"data-center","description":" A data center (or datacenter) is a facility composed of networked computers and storage that businesses or other organizations use to organize, process, store and disseminate large amounts of data.

This allows for much more accurate budgeting, especially as compared to the costs of internal IT to manage upgrades and address issues for an owned instance.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">The SaaS vendor is responsible for upgrades, uptime and security</span>. Under the SaaS model, since the software is hosted by the vendor, they take on the responsibility for maintaining the software and upgrading it, ensuring that it is reliable and meeting agreed-upon service level agreements, and keeping the application and its data secure.&nbsp; While some IT people worry about Software as a Service security outside of the enterprise walls, the likely truth is that the vendor has a much higher level of security than the enterprise itself would provide. Many will have redundant instances in very secure data centers in multiple geographies.&nbsp; Also, the data is being automatically backed up by the vendor, providing additional security and peace of mind. Because of the data center hosting, you’re getting the added benefit of at least some disaster recovery. Lastly, the vendor manages these issues as part of their core competencies—let them.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Integration and scalability.</span> Most SaaS apps are designed to support some amount of customization for the way you do business. SaaS vendors create APIs to allow connections not only to internal applications like ERPs or CRMs but also to other SaaS providers. One of the terrific aspects of integration is that orders written in the field can be automatically sent to the ERP. Now a salesperson in the field can check inventory through the catalog, write the order in front of the customer for approval, send it and receive confirmation, all in minutes. And as you scale with a SaaS vendor, there’s no need to invest in server capacity and software licenses. </li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Work anywhere</span>. Since the software is hosted in the cloud and accessible over the internet, users can access it via mobile devices wherever they are connected. This includes checking customer order histories prior to a sales call, as well as having access to real time data and real time order taking with the customer.</li></ul>\r\n<p class=\"align-left\">&nbsp;</p>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/SaaS__1_.png"},{"id":299,"title":"Application and User Session Virtualization","alias":"application-and-user-session-virtualization","description":"Application virtualization is a technology that allows you to separate the software from the operating system on which it operates.

ITSM is focused on aligning IT processes and services with business objectives to help an organization grow.\r\nITSM positions IT services as the key means of delivering and obtaining value, where an internal or external IT service provider works with business customers, at the same time taking responsibility for the associated costs and risks. ITSM works across the whole lifecycle of a service, from the original strategy, through design, transition and into live operation.\r\nTo ensure sustainable quality of IT services, ITSM establishes a set of practices, or processes, constituting a service management system. There are industrial, national and international standards for IT service management solutions, setting up requirements and good practices for the management system. \r\nITSM system is based on a set of principles, such as focusing on value and continual improvement. It is not just a set of processes – it is a cultural mindset to ensure that the desired outcome for the business is achieved. \r\n<span style=\"font-weight: bold; \">ITIL (IT Infrastructure Library)</span> is a framework of best practices and recommendations for managing an organization's IT operations and services. IT service management processes, when built based on the ITIL framework, pave the way for better IT service operations management and improved business. To summarize, ITIL is a set of guidelines for effective IT service management best practices. ITIL has evolved beyond the delivery of services to providing end-to-end value delivery. The focus is now on the co-creation of value through service relationships. \r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">ITSM processes typically include five stages, all based on the ITIL framework:</span></p>\r\n<span style=\"font-weight: bold; \">ITSM strategy.</span> This stage forms the foundation or the framework of an organization's ITSM process building. It involves defining the services that the organization will offer, strategically planning processes, and recognizing and developing the required assets to keep processes moving. \r\n<span style=\"font-weight: bold; \">Service design.</span> This stage's main aim is planning and designing the IT services the organization offers to meet business demands. It involves creating and designing new services as well as assessing current services and making relevant improvements.\r\n<span style=\"font-weight: bold; \">Service transition.</span> Once the designs for IT services and their processes have been finalized, it's important to build them and test them out to ensure that processes flow. IT teams need to ensure that the designs don't disrupt services in any way, especially when existing IT service processes are upgraded or redesigned. This calls for change management, evaluation, and risk management. \r\n<span style=\"font-weight: bold; \">Service operation. </span>This phase involves implementing the tried and tested new or modified designs in a live environment. While in this stage, the processes have already been tested and the issues fixed, but new processes are bound to have hiccups—especially when customers start using the services. \r\n<span style=\"font-weight: bold;\">Continual service improvement (CSI).</span> Implementing IT processes successfully shouldn't be the final stage in any organization. There's always room for improvement and new development based on issues that pop up, customer needs and demands, and user feedback.\r\n\r\n","materialsDescription":"<h1 class=\"align-center\">Benefits of efficient ITSM processes</h1>\r\nIrrespective of the size of business, every organization is involved in IT service management in some way. ITSM ensures that incidents, service requests, problems, changes, and IT assets—in addition to other aspects of IT services—are managed in a streamlined way.\r\nIT teams in your organization can employ various workflows and best practices in ITSM, as outlined in ITIL. Effective IT service management can have positive effects on an IT organization's overall function.\r\nHere are the 10 key benefits of ITSM:\r\n<ul><li>&nbsp;&nbsp;&nbsp; Lower costs for IT operations</li><li>&nbsp;&nbsp;&nbsp; Higher returns on IT investments</li><li>&nbsp;&nbsp;&nbsp; Minimal service outages</li><li>&nbsp;&nbsp;&nbsp; Ability to establish well-defined, repeatable, and manageable IT processes</li><li>&nbsp;&nbsp;&nbsp; Efficient analysis of IT problems to reduce repeat incidents</li><li>&nbsp;&nbsp;&nbsp; Improved efficiency of IT help desk teams</li><li>&nbsp;&nbsp;&nbsp; Well-defined roles and responsibilities</li><li>&nbsp;&nbsp;&nbsp; Clear expectations on service levels and service availability</li><li>&nbsp;&nbsp;&nbsp; Risk-free implementation of IT changes</li><li>&nbsp;&nbsp;&nbsp; Better transparency into IT processes and services</li></ul>\r\n<h1 class=\"align-center\">How to choose an ITSM tool?</h1>\r\nWith a competent IT service management goal in mind, it's important to invest in a service desk solution that caters to your business needs. It goes without saying, with more than 150 service desk tools to choose from, selecting the right one is easier said than done. Here are a few things to keep in mind when choosing an ITSM products:\r\n<span style=\"font-weight: bold; \">Identify key processes and their dependencies. </span>Based on business goals, decide which key ITSM processes need to be implemented and chart out the integrations that need to be established to achieve those goals. \r\n<span style=\"font-weight: bold; \">Consult with ITSM experts.</span> Participate in business expos, webinars, demos, etc., and educate yourself about the various options that are available in the market. Reports from expert analysts such as Gartner and Forrester are particularly useful as they include reviews of almost every solution, ranked based on multiple criteria.\r\n<span style=\"font-weight: bold; \">Choose a deployment option.</span> Every business has a different IT infrastructure model. Selecting an on-premises or software as a service (SaaS IT service management) tool depends on whether your business prefers to host its applications and data on its own servers or use a public or private cloud.\r\n<span style=\"font-weight: bold; \">Plan ahead for the future.</span> Although it's important to consider the &quot;needs&quot; primarily, you shouldn't rule out the secondary or luxury capabilities. If the ITSM tool doesn't have the potential to adapt to your needs as your organization grows, it can pull you back from progressing. Draw a clear picture of where your business is headed and choose an service ITSM that is flexible and technology-driven.\r\n<span style=\"font-weight: bold;\">Don't stop with the capabilities of the ITSM tool.</span> It might be tempting to assess an ITSM tool based on its capabilities and features but it's important to evaluate the vendor of the tool. A good IT support team, and a vendor that is endorsed for their customer-vendor relationship can take your IT services far. Check Gartner's magic quadrant and other analyst reports, along with product and support reviews to ensure that the said tool provides good customer support.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_ITSM.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":2545,"logo":false,"scheme":false,"title":"VMWARE vRealize Network Insight","vendorVerified":0,"rating":"2.40","implementationsCount":1,"suppliersCount":0,"alias":"vmware-vrealize-network-insight","companyTypes":[],"description":"VMware vRealize Network Insight helps customers build an optimized, highly available and secure network infrastructure across multi-cloud environments.

Pools of hypervisors within the cloud operational system can support large numbers of virtual machines and the ability to scale services up and down according to customers' varying requirements.\r\nTypically IaaS solutions involve the use of a cloud orchestration technology like Open Stack, Apache Cloudstack or Open Nebula. This manages the creation of a virtual machine and decides on which hypervisor (i.e. physical host) to start it, enables VM migration features between hosts, allocates storage volumes and attaches them to VMs, usage information for billing and lots more.\r\nAn alternative to hypervisors are Linux containers, which run in isolated partitions of a single Linux kernel running directly on the physical hardware. Linux cgroups and namespaces are the underlying Linux kernel technologies used to isolate, secure and manage the containers. Containerisation offers higher performance than virtualization, because there is no hypervisor overhead. Also, container capacity auto-scales dynamically with computing load, which eliminates the problem of over-provisioning and enables usage-based billing.\r\nIaaS clouds often offer additional resources such as a virtual-machine disk-image library, raw block storage, file or object storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles.\r\nAccording to the Internet Engineering Task Force (IETF), the most basic cloud-service model is that of providers offering IT infrastructure – virtual machines and other resources – as a service to subscribers.\r\nIaaS cloud providers supply these resources on-demand from their large pools of equipment installed in data centers. For wide-area connectivity, customers can use either the Internet or carrier clouds (dedicated virtual private networks). To deploy their applications, cloud users install operating-system images and their application software on the cloud infrastructure. In this model, the cloud user patches and maintains the operating systems and the application software. Cloud infrastructure providers typically bill IaaS services on a utility computing basis: cost reflects the amount of resources allocated and consumed.","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: bold; \">Infrastructure as a Service Benefits&nbsp;</span></h1>\r\n<span style=\"font-weight: bold; \">Cost savings:</span> An obvious benefit of moving to the managed IaaS model is lower infrastructure costs. No longer do organizations have the responsibility of ensuring uptime, maintaining hardware and networking equipment, or replacing old equipment. IaaS&nbsp; technology also saves enterprises from having to buy more capacity to deal with sudden business spikes. Organizations with a smaller IT infrastructure generally require a smaller IT staff as well. The pay-as-you-go model also provides significant cost savings. \r\n<span style=\"font-weight: bold; \">Scalability and flexibility:</span> One of the greatest benefits of IaaS is the ability to scale up and down quickly in response to an enterprise’s requirements. Infrastructure as a Service providers generally have the latest, most powerful storage, servers and networking technology to accommodate the needs of their customers. This on-demand scalability provides added flexibility and greater agility to respond to changing opportunities and requirements. \r\n<span style=\"font-weight: bold; \">Faster time to market:</span> Competition is strong in every sector, and time to market is one of the best ways to beat the competition. Because IaaS vendors elasticity and scalability, organizations can ramp up and get the job done (and the product or service to market) more rapidly.\r\n<span style=\"font-weight: bold; \">Support for DR, BC and high availability:</span> While every enterprise has some type of disaster recovery plan, the technology behind those plans is often expensive and unwieldy. Organizations with several disparate locations often have different disaster recovery and business continuity plans and technologies, making management virtually impossible.\r\n<span style=\"font-weight: bold; \">Focus on business growth:</span> Time, money and energy spent making technology decisions and hiring staff to manage and maintain the technology infrastructure is time not spent on growing the business. By moving infrastructure to a global infrastructure services, organizations can focus their time and resources where they belong, on developing innovations in applications and solutions.\r\n<h1 class=\"align-center\">IaaS, PaaS and SaaS: What’s the Difference?</h1>\r\nPlatform as a Service (PaaS) is the next step up from IaaS products, where the provider also supplies the operating environment including the operating system, application services, middleware and other ‘runtimes’ for cloud users. It’s used for development environments where the business can focus on creating an app but wants someone else to maintain the deployment platform. It means you have much simpler workloads but you can’t necessarily be as flexible as you want.\r\nAt the highest level of orchestration is Software as a Service. In SaaS infrastructure applications are accessed on demand. Here you just open your browser and go, consuming software rather than installing and running it. A user simply logs on to access the provider’s application. Users can decide how the app will work but pretty much everything else is the responsibility of the software provider.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_IaaS.png"},{"id":299,"title":"Application and User Session Virtualization","alias":"application-and-user-session-virtualization","description":"Application virtualization is a technology that allows you to separate the software from the operating system on which it operates.

At a minimum, data centers serve as the principal repositories for all manner of IT equipment, including servers, storage subsystems, networking switches, routers and firewalls, as well as the cabling and physical racks used to organize and interconnect the IT equipment. A data center must also contain an adequate infrastructure, such as power distribution and supplemental power subsystems, including electrical switching; uninterruptable power supplies; backup generators and so on; ventilation and data center cooling systems, such as computer room air conditioners; and adequate provisioning for network carrier (telco) connectivity. All of this demands a physical facility with physical security and sufficient physical space to house the entire collection of infrastructure and equipment.","materialsDescription":" <span style=\"font-weight: bold;\">What are the requirements for modern data centers?</span>\r\nModernization and data center transformation enhances performance and energy efficiency.\r\nInformation security is also a concern, and for this reason a data center has to offer a secure environment which minimizes the chances of a security breach.

The equipment may be used to:\r\n<ul><li>Operate and manage a carrier's telecommunication network</li><li>Provide data center based applications directly to the carrier's customers</li><li>Provide hosted applications for a third party to provide services to their customers</li><li>Provide a combination of these and similar data center applications</li></ul>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Data center transformation</span></span>\r\nData center transformation takes a step-by-step approach through integrated projects carried out over time. This differs from a traditional method of data center upgrades that takes a serial and siloed approach. The typical projects within a data center transformation initiative include standardization/consolidation, virtualization, automation and security.\r\n<ul><li>Standardization/consolidation: Reducing the number of data centers and avoiding server sprawl (both physical and virtual) often includes replacing aging data center equipment, and is aided by standardization.</li><li>Virtualization: Lowers capital and operational expenses, reduce energy consumption. Virtualized desktops can be hosted in data centers and rented out on a subscription basis. Investment bank Lazard Capital Markets estimated in 2008 that 48 percent of enterprise operations will be virtualized by 2012. Gartner views virtualization as a catalyst for modernization.</li><li>Automating: Automating tasks such as provisioning, configuration, patching, release management and compliance is needed, not just when facing fewer skilled IT workers.</li><li>Securing: Protection of virtual systems is integrated with existing security of physical infrastructures.</li></ul>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Machine room</span></span>\r\nThe term &quot;Machine Room&quot; is at times used to refer to the large room within a Data Center where the actual Central Processing Unit is located; this may be separate from where high-speed printers are located. Air conditioning is most important in the machine room.\r\nAside from air-conditioning, there must be monitoring equipment, one type of which is to detect water prior to flood-level situations.

To fully grasp how VMs work, it’s important to first understand how computer software and hardware are typically integrated by an operating system.\r\n&quot;The cloud&quot; refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies don't have to manage physical servers themselves or run software applications on their own machines.\r\nThe cloud enables users to access the same files and applications from almost any device, because the computing and storage take place on servers in a data center, instead of locally on the user device. This is why a user can log into their Instagram account on a new phone after their old phone breaks and still find their old account in place, with all their photos, videos, and conversation history. It works the same way with cloud email providers like Gmail or Microsoft Office 365, and with cloud storage providers like Dropbox or Google Drive.\r\nFor businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact on small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access the same files and applications from any location.\r\nSeveral cloud providers offer virtual machines to their customers. These virtual machines typically live on powerful servers that can act as a host to multiple VMs and can be used for a variety of reasons that wouldn’t be practical with a locally-hosted VM. These include:\r\n<ul><li>Running SaaS applications - Software-as-a-Service, or SaaS for short, is a cloud-based method of providing software to users. SaaS users subscribe to an application rather than purchasing it once and installing it. These applications are generally served to the user over the Internet. Often, it is virtual machines in the cloud that are doing the computation for SaaS applications as well as delivering them to users. If the cloud provider has a geographically distributed network edge, then the application will run closer to the user, resulting in faster performance.</li><li>Backing up data - Cloud-based VM services are very popular for backing up data because the data can be accessed from anywhere. Plus, cloud VMs provide better redundancy, require less maintenance, and generally scale better than physical data centers. (For example, it’s generally fairly easy to buy an extra gigabyte of storage space from a cloud VM provider, but much more difficult to build a new local data server for that extra gigabyte of data.)</li><li>Hosting services like email and access management - Hosting these services on cloud VMs is generally faster and more cost-effective, and helps minimize maintenance and offload security concerns as well.</li></ul>","materialsDescription":"What is an operating system?\r\nTraditional computers are built out of physical hardware, including hard disk drives, processor chips, RAM, etc. In order to utilize this hardware, computers rely on a type of software known as an operating system (OS). Some common examples of OSes are Mac OSX, Microsoft Windows, Linux, and Android.\r\nThe OS is what manages the computer’s hardware in ways that are useful to the user. For example, if the user wants to access the Internet, the OS directs the network interface card to make the connection. If the user wants to download a file, the OS will partition space on the hard drive for that file. The OS also runs and manages other pieces of software. For example, it can run a web browser and provide the browser with enough random access memory (RAM) to operate smoothly. Typically, operating systems exist within a physical computer at a one-to-one ratio; for each machine, there is a single OS managing its physical resources.\r\n<span style=\"font-weight: bold;\">Can you have two or more operating systems on one computer?</span>\r\nSome users want to be able to run multiple operating systems simultaneously on one computer, either for testing or one of the other reasons listed in the section below. This can be achieved through a process called virtualization. In virtualization, a piece of software behaves as if it were an independent computer. This piece of software is called a virtual machine, also known as a ‘guest’ computer. (The computer on which the VM is running is called the ‘host’.) The guest has an OS as well as its own virtual hardware.\r\n‘Virtual hardware’ may sound like a bit of an oxymoron, but it works by mapping to real hardware on the host computer. For example, the VM’s ‘hard drive’ is really just a file on the host computer’s hard drive. When the VM wants to save a new file, it actually has to communicate with the host OS, which will write this file to the host hard drive. Because virtual hardware must perform this added step of negotiating with the host to access hardware resources, virtual machines can’t run quite as fast as their host computers.\r\nWith virtualization, one computer can run two or more operating systems. The number of VMs that can run on one host is limited only by the host’s available resources. The user can run the OS of a VM in a window like any other program, or they can run it in fullscreen so that it looks and feels like a genuine host OS.\r\n <span style=\"font-weight: bold; \">What are virtual machines used for?</span>\r\nSome of the most popular reasons people run virtual machines include:\r\n<span style=\"font-weight: bold; \">Testing</span> - Oftentimes software developers want to be able to test their applications in different environments. They can use virtual machines to run their applications in various OSes on one computer. This is simpler and more cost-effective than having to test on several different physical machines.\r\n<span style=\"font-weight: bold; \">Running software designed for other OSes</span> - Although certain software applications are only available for a single platform, a VM can run software designed for a different OS. For example, a Mac user who wants to run software designed for Windows can run a Windows VM on their Mac host.\r\n<span style=\"font-weight: bold; \">Running outdated software</span> - Some pieces of older software can’t be run in modern OSes. Users who want to run these applications can run an old OS on a virtual machine.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Virtual_machine_and_cloud_system_software.png"},{"id":1,"title":"Desktop virtualization","alias":"desktop-virtualization","description":" Desktop virtualization is a virtualization technology that separates an individual's PC applications from his or her desktop. Virtualized desktops are generally hosted on a remote central server, rather than the hard drive of the personal computer. Because the client-server computing model is used in virtualizing desktops, desktop virtualization is also known as client virtualization.\r\nDesktop virtualization provides a way for users to maintain their individual desktops on a single, central server. The users may be connected to the central server through a LAN, WAN or over the Internet.\r\nDesktop virtualization has many benefits, including a lower total cost of ownership (TCO), increased security, reduced energy costs, reduced downtime and centralized management.\r\nLimitations of desktop virtualization include difficulty in maintenance and set up of printer drivers; increased downtime in case of network failures; complexity and costs involved in VDI deployment and security risks in the event of improper network management.<br /><br />","materialsDescription":" <span style=\"font-weight: bold; \">What are types of desktop virtualization technologies?</span>\r\nHost-based forms of desktop virtualization require that users view and interact with their virtual desktops over a network by using a remote display protocol. Because processing takes place in a data center, client devices can be traditional PCs, but also thin clients, zero clients, smartphones and tablets. Examples of host-based desktop virtualization technology include:\r\n<span style=\"font-weight: bold; \">Host-based virtual machines:</span> Each user connects to an individual VM that is hosted in a data center. The user may connect to the same VM every time, allowing for personalization (known as a persistent desktop), or be given a fresh VM at each login (a nonpersistent desktop).\r\n<span style=\"font-weight: bold; \">Shared hosted:</span> Users connect to a shared desktop that runs on a server. Microsoft Remote Desktop Services, formerly Terminal Services, takes this client-server approach. Users may also connect to individual applications running on a server; this technology is an example of application virtualization.\r\n<span style=\"font-weight: bold; \">Host-based physical machines:</span> The operating system runs directly on another device's physical hardware.\r\nClient virtualization requires processing to occur on local hardware; the use of thin clients, zero clients and mobile devices is not possible. These types of desktop virtualization include:\r\n<span style=\"font-weight: bold; \">OS image streaming:</span> The operating system runs on local hardware, but it boots to a remote disk image across the network. This is useful for groups of desktops that use the same disk image. OS image streaming, also known as remote desktop virtualization, requires a constant network connection in order to function.\r\n<span style=\"font-weight: bold; \">Client-based virtual machines:</span> A VM runs on a fully functional PC, with a hypervisor in place. Client-based virtual machines can be managed by regularly syncing the disk image with a server, but a constant network connection is not necessary in order for them to function.\r\n<span style=\"font-weight: bold;\">Desktop virtualization vs. virtual desktop infrastructure</span>\r\nThe terms <span style=\"font-style: italic;\">desktop virtualization</span> and virtual desktop infrastructure (VDI) are often used interchangeably, but they are not the same. While VDI is a type of desktop virtualization, not all desktop virtualization uses VDI.\r\nVDI refers to the use of host-based VMs to deliver virtual desktops, which emerged in 2006 as an alternative to Terminal Services and Citrix's client-server approach to desktop virtualization technology. Other types of desktop virtualization -- including the shared hosted model, host-based physical machines and all methods of client virtualization -- are not examples of VDI.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Desktop_virtualization.png"},{"id":34,"title":"ITSM - IT Service Management","alias":"itsm-it-service-management","description":"<span style=\"font-weight: bold; \">IT service management (ITSM)</span> is the process of designing, delivering, managing, and improving the IT services an organization provides to its end users. ITSM is focused on aligning IT processes and services with business objectives to help an organization grow.\r\nITSM positions IT services as the key means of delivering and obtaining value, where an internal or external IT service provider works with business customers, at the same time taking responsibility for the associated costs and risks. ITSM works across the whole lifecycle of a service, from the original strategy, through design, transition and into live operation.\r\nTo ensure sustainable quality of IT services, ITSM establishes a set of practices, or processes, constituting a service management system. There are industrial, national and international standards for IT service management solutions, setting up requirements and good practices for the management system. \r\nITSM system is based on a set of principles, such as focusing on value and continual improvement. It is not just a set of processes – it is a cultural mindset to ensure that the desired outcome for the business is achieved. \r\n<span style=\"font-weight: bold; \">ITIL (IT Infrastructure Library)</span> is a framework of best practices and recommendations for managing an organization's IT operations and services. IT service management processes, when built based on the ITIL framework, pave the way for better IT service operations management and improved business. To summarize, ITIL is a set of guidelines for effective IT service management best practices. ITIL has evolved beyond the delivery of services to providing end-to-end value delivery. The focus is now on the co-creation of value through service relationships. \r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">ITSM processes typically include five stages, all based on the ITIL framework:</span></p>\r\n<span style=\"font-weight: bold; \">ITSM strategy.</span> This stage forms the foundation or the framework of an organization's ITSM process building.

It involves creating and designing new services as well as assessing current services and making relevant improvements.\r\n<span style=\"font-weight: bold; \">Service transition.</span> Once the designs for IT services and their processes have been finalized, it's important to build them and test them out to ensure that processes flow. IT teams need to ensure that the designs don't disrupt services in any way, especially when existing IT service processes are upgraded or redesigned. This calls for change management, evaluation, and risk management. \r\n<span style=\"font-weight: bold; \">Service operation. </span>This phase involves implementing the tried and tested new or modified designs in a live environment.

There's always room for improvement and new development based on issues that pop up, customer needs and demands, and user feedback.\r\n\r\n","materialsDescription":"<h1 class=\"align-center\">Benefits of efficient ITSM processes</h1>\r\nIrrespective of the size of business, every organization is involved in IT service management in some way. ITSM ensures that incidents, service requests, problems, changes, and IT assets—in addition to other aspects of IT services—are managed in a streamlined way.\r\nIT teams in your organization can employ various workflows and best practices in ITSM, as outlined in ITIL. Effective IT service management can have positive effects on an IT organization's overall function.\r\nHere are the 10 key benefits of ITSM:\r\n<ul><li>&nbsp;&nbsp;&nbsp; Lower costs for IT operations</li><li>&nbsp;&nbsp;&nbsp; Higher returns on IT investments</li><li>&nbsp;&nbsp;&nbsp; Minimal service outages</li><li>&nbsp;&nbsp;&nbsp; Ability to establish well-defined, repeatable, and manageable IT processes</li><li>&nbsp;&nbsp;&nbsp; Efficient analysis of IT problems to reduce repeat incidents</li><li>&nbsp;&nbsp;&nbsp; Improved efficiency of IT help desk teams</li><li>&nbsp;&nbsp;&nbsp; Well-defined roles and responsibilities</li><li>&nbsp;&nbsp;&nbsp; Clear expectations on service levels and service availability</li><li>&nbsp;&nbsp;&nbsp; Risk-free implementation of IT changes</li><li>&nbsp;&nbsp;&nbsp; Better transparency into IT processes and services</li></ul>\r\n<h1 class=\"align-center\">How to choose an ITSM tool?</h1>\r\nWith a competent IT service management goal in mind, it's important to invest in a service desk solution that caters to your business needs. It goes without saying, with more than 150 service desk tools to choose from, selecting the right one is easier said than done. Here are a few things to keep in mind when choosing an ITSM products:\r\n<span style=\"font-weight: bold; \">Identify key processes and their dependencies. </span>Based on business goals, decide which key ITSM processes need to be implemented and chart out the integrations that need to be established to achieve those goals. \r\n<span style=\"font-weight: bold; \">Consult with ITSM experts.</span> Participate in business expos, webinars, demos, etc., and educate yourself about the various options that are available in the market. Reports from expert analysts such as Gartner and Forrester are particularly useful as they include reviews of almost every solution, ranked based on multiple criteria.\r\n<span style=\"font-weight: bold; \">Choose a deployment option.</span> Every business has a different IT infrastructure model. Selecting an on-premises or software as a service (SaaS IT service management) tool depends on whether your business prefers to host its applications and data on its own servers or use a public or private cloud.\r\n<span style=\"font-weight: bold; \">Plan ahead for the future.</span> Although it's important to consider the &quot;needs&quot; primarily, you shouldn't rule out the secondary or luxury capabilities. If the ITSM tool doesn't have the potential to adapt to your needs as your organization grows, it can pull you back from progressing. Draw a clear picture of where your business is headed and choose an service ITSM that is flexible and technology-driven.\r\n<span style=\"font-weight: bold;\">Don't stop with the capabilities of the ITSM tool.</span> It might be tempting to assess an ITSM tool based on its capabilities and features but it's important to evaluate the vendor of the tool. A good IT support team, and a vendor that is endorsed for their customer-vendor relationship can take your IT services far. Check Gartner's magic quadrant and other analyst reports, along with product and support reviews to ensure that the said tool provides good customer support.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_ITSM.png"},{"id":52,"title":"SaaS - software as a service","alias":"saas-software-as-a-service","description":"<span style=\"font-weight: bold;\">Software as a service (SaaS)</span> is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted. It is sometimes referred to as &quot;on-demand software&quot;, and was formerly referred to as &quot;software plus services&quot; by Microsoft.\r\n SaaS services is typically accessed by users using a thin client, e.g. via a web browser. SaaS software solutions has become a common delivery model for many business applications, including office software, messaging software, payroll processing software, DBMS software, management software, CAD software, development software, gamification, virtualization, accounting, collaboration, customer relationship management (CRM), Management Information Systems (MIS), enterprise resource planning (ERP), invoicing, human resource management (HRM), talent acquisition, learning management systems, content management (CM), Geographic Information Systems (GIS), and service desk management. SaaS has been incorporated into the strategy of nearly all leading enterprise software companies.\r\nSaaS applications are also known as <span style=\"font-weight: bold;\">Web-based software</span>, <span style=\"font-weight: bold;\">on-demand software</span> and<span style=\"font-weight: bold;\"> hosted software</span>.\r\nThe term &quot;Software as a Service&quot; (SaaS) is considered to be part of the nomenclature of cloud computing, along with Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Desktop as a Service (DaaS),managed software as a service (MSaaS), mobile backend as a service (MBaaS), and information technology management as a service (ITMaaS).\r\nBecause SaaS is based on cloud computing it saves organizations from installing and running applications on their own systems. That eliminates or at least reduces the associated costs of hardware purchases and maintenance and of software and support. The initial setup cost for a SaaS application is also generally lower than it for equivalent enterprise software purchased via a site license.\r\nSometimes, the use of SaaS cloud software can also reduce the long-term costs of software licensing, though that depends on the pricing model for the individual SaaS offering and the enterprise’s usage patterns. In fact, it’s possible for SaaS to cost more than traditional software licenses. This is an area IT organizations should explore carefully.<br />SaaS also provides enterprises the flexibility inherent with cloud services: they can subscribe to a SaaS offering as needed rather than having to buy software licenses and install the software on a variety of computers. The savings can be substantial in the case of applications that require new hardware purchases to support the software.<br /><br /><br /><br />","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: normal;\">Who uses SaaS?</span></h1>\r\nIndustry analyst Forrester Research notes that SaaS adoption has so far been concentrated mostly in human resource management (HRM), customer relationship management (CRM), collaboration software (e.g., email), and procurement solutions, but is poised to widen. Today it’s possible to have a data warehouse in the cloud that you can access with business intelligence software running as a service and connect to your cloud-based ERP like NetSuite or Microsoft Dynamics.The dollar savings can run into the millions. And SaaS installations are often installed and working in a fraction of the time of on-premises deployments—some can be ready in hours. \r\nSales and marketing people are likely familiar with Salesforce.com, the leading SaaS CRM software, with millions of users across more than 100,000 customers. Sales is going SaaS too, with apps available to support sales in order management, compensation, quote production and configure, price, quoting, electronic signatures, contract management and more.\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">Why SaaS? Benefits of software as a service</span></h1>\r\n<ul><li><span style=\"font-weight: bold;\">Lower cost of entry</span>. With SaaS solution, you pay for what you need, without having to buy hardware to host your new applications. Instead of provisioning internal resources to install the software, the vendor provides APIs and performs much of the work to get their software working for you. The time to a working solution can drop from months in the traditional model to weeks, days or hours with the SaaS model. In some businesses, IT wants nothing to do with installing and running a sales app. In the case of funding software and its implementation, this can be a make-or-break issue for the sales and marketing budget, so the lower cost really makes the difference.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Reduced time to benefit/rapid prototyping</span>. In the SaaS model, the software application is already installed and configured. Users can provision the server for the cloud and quickly have the application ready for use. This cuts the time to benefit and allows for rapid demonstrations and prototyping. With many SaaS companies offering free trials, this means a painless proof of concept and discovery phase to prove the benefit to the organization. </li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Pay as you go</span>. SaaS business software gives you the benefit of predictable costs both for the subscription and to some extent, the administration. Even as you scale, you can have a clear idea of what your costs will be. This allows for much more accurate budgeting, especially as compared to the costs of internal IT to manage upgrades and address issues for an owned instance.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">The SaaS vendor is responsible for upgrades, uptime and security</span>. Under the SaaS model, since the software is hosted by the vendor, they take on the responsibility for maintaining the software and upgrading it, ensuring that it is reliable and meeting agreed-upon service level agreements, and keeping the application and its data secure.&nbsp; While some IT people worry about Software as a Service security outside of the enterprise walls, the likely truth is that the vendor has a much higher level of security than the enterprise itself would provide. Many will have redundant instances in very secure data centers in multiple geographies.&nbsp; Also, the data is being automatically backed up by the vendor, providing additional security and peace of mind. Because of the data center hosting, you’re getting the added benefit of at least some disaster recovery. Lastly, the vendor manages these issues as part of their core competencies—let them.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Integration and scalability.</span> Most SaaS apps are designed to support some amount of customization for the way you do business. SaaS vendors create APIs to allow connections not only to internal applications like ERPs or CRMs but also to other SaaS providers. One of the terrific aspects of integration is that orders written in the field can be automatically sent to the ERP. Now a salesperson in the field can check inventory through the catalog, write the order in front of the customer for approval, send it and receive confirmation, all in minutes. And as you scale with a SaaS vendor, there’s no need to invest in server capacity and software licenses. </li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Work anywhere</span>. Since the software is hosted in the cloud and accessible over the internet, users can access it via mobile devices wherever they are connected. This includes checking customer order histories prior to a sales call, as well as having access to real time data and real time order taking with the customer.</li></ul>\r\n<p class=\"align-left\">&nbsp;</p>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/SaaS__1_.png"},{"id":299,"title":"Application and User Session Virtualization","alias":"application-and-user-session-virtualization","description":"Application virtualization is a technology that allows you to separate the software from the operating system on which it operates. Fully virtualized software is not installed in the traditional sense, although the end-user at first glance can not see it, because the virtualized software works just as normal. The software in the execution process works just as if it interacted with the operating system directly and with all its resources, but can be isolated or executed in a sandbox with different levels of restriction.\r\nModern operating systems, such as Microsoft Windows and Linux, can include limited software virtualization. For example, Windows 7 has Windows XP mode that allows you to run Windows XP software on Windows 7 without any changes.\r\nUser session virtualization is a newer version of desktop virtualization that works at the operating system level. While normal virtualization of the desktop allows an operating system to be run by virtualizing the hardware of the desktop, RDS and App-V allow for the virtualization of the applications. User session virtualization lies between the two.\r\nA desktop has an operating system loaded on the base hardware. This can be either physical or virtual. The user session virtualization keeps track of all changes to the operating system that a user might make by encapsulating the configuration changes and associating them to the user account. This allows the specific changes to be applied to the underlying operating system without actually changing it. This allows several users to have completely different operating system configurations applied to base operating system installation.\r\nIf you are in a distributed desktop environment and there are local file servers available at each location, you can deploy virtualized user sessions in the form of redirected folders and roaming profiles.","materialsDescription":" <span style=\"font-weight: bold;\">Understanding application virtualization</span>\r\nApplication virtualization technology isolates applications from the underlying operating system and from other applications to increase compatibility and manageability. This application virtualization technology enables applications to be streamed from a centralized location into an isolation environment on the target device where they will execute. The application files, configuration, and settings are copied to the target device and the application execution at run time is controlled by the application virtualization layer. When executed, the application run time believes that it is interfacing directly with the operating system when, in fact, it is interfacing with a virtualization environment that proxies all requests to the operating system.\r\n<span style=\"font-weight: bold;\">Understanding session virtualization</span>\r\nSession virtualization uses application streaming to deliver applications to hosting servers in the datacenter. The Application then connects the user to the server. The application then executes entirely on the server. The user interacts with the application remotely by sending mouse-clicks and keystrokes to the server. The server then responds by sending screen updates back to the user’s device. Whereas application virtualization is limited to Windows-based operating systems, session virtualization allows any user on any operating system to access any application delivered by IT. As a result, the application enables Windows, Mac, Linux, iOS and Android devices to run any applications using session virtualization. Furthermore, session virtualization leverages server-side processing power which liberates IT from the endless cycle of PC hardware refreshes which are typically needed to support application upgrades when using traditional application deployment methods.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Application_and_User_Session_Virtualization__1_.png"},{"id":4,"title":"Data center","alias":"data-center","description":" A data center (or datacenter) is a facility composed of networked computers and storage that businesses or other organizations use to organize, process, store and disseminate large amounts of data.

At a minimum, data centers serve as the principal repositories for all manner of IT equipment, including servers, storage subsystems, networking switches, routers and firewalls, as well as the cabling and physical racks used to organize and interconnect the IT equipment. A data center must also contain an adequate infrastructure, such as power distribution and supplemental power subsystems, including electrical switching; uninterruptable power supplies; backup generators and so on; ventilation and data center cooling systems, such as computer room air conditioners; and adequate provisioning for network carrier (telco) connectivity.

A data center must therefore keep high standards for assuring the integrity and functionality of its hosted computer environment.\r\nIndustry research company International Data Corporation (IDC) puts the average age of a data center at nine years old. Gartner, another research company, says data centers older than seven years are obsolete. The growth in data (163 zettabytes by 2025) is one factor driving the need for data centers to modernize.\r\nFocus on modernization is not new: Concern about obsolete equipment was decried in 2007, and in 2011 Uptime Institute was concerned about the age of the equipment therein. By 2018 concern had shifted once again, this time to the age of the staff: &quot;data center staff are aging faster than the equipment.&quot;\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Meeting standards for data centers</span></span>\r\nThe Telecommunications Industry Association's Telecommunications Infrastructure Standard for Data Centers specifies the minimum requirements for telecommunications infrastructure of data centers and computer rooms including single tenant enterprise data centers and multi-tenant Internet hosting data centers. The topology proposed in this document is intended to be applicable to any size data center.\r\nTelcordia GR-3160, NEBS Requirements for Telecommunications Data Center Equipment and Spaces, provides guidelines for data center spaces within telecommunications networks, and environmental requirements for the equipment intended for installation in those spaces. These criteria were developed jointly by Telcordia and industry representatives. They may be applied to data center spaces housing data processing or Information Technology (IT) equipment. The equipment may be used to:\r\n<ul><li>Operate and manage a carrier's telecommunication network</li><li>Provide data center based applications directly to the carrier's customers</li><li>Provide hosted applications for a third party to provide services to their customers</li><li>Provide a combination of these and similar data center applications</li></ul>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Data center transformation</span></span>\r\nData center transformation takes a step-by-step approach through integrated projects carried out over time. This differs from a traditional method of data center upgrades that takes a serial and siloed approach. The typical projects within a data center transformation initiative include standardization/consolidation, virtualization, automation and security.\r\n<ul><li>Standardization/consolidation: Reducing the number of data centers and avoiding server sprawl (both physical and virtual) often includes replacing aging data center equipment, and is aided by standardization.</li><li>Virtualization: Lowers capital and operational expenses, reduce energy consumption. Virtualized desktops can be hosted in data centers and rented out on a subscription basis. Investment bank Lazard Capital Markets estimated in 2008 that 48 percent of enterprise operations will be virtualized by 2012. Gartner views virtualization as a catalyst for modernization.</li><li>Automating: Automating tasks such as provisioning, configuration, patching, release management and compliance is needed, not just when facing fewer skilled IT workers.</li><li>Securing: Protection of virtual systems is integrated with existing security of physical infrastructures.</li></ul>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Machine room</span></span>\r\nThe term &quot;Machine Room&quot; is at times used to refer to the large room within a Data Center where the actual Central Processing Unit is located; this may be separate from where high-speed printers are located. Air conditioning is most important in the machine room.\r\nAside from air-conditioning, there must be monitoring equipment, one type of which is to detect water prior to flood-level situations. One company, for several decades, has had share-of-mind: Water Alert. The company, as of 2018, has 2 competing manufacturers (Invetex, Hydro-Temp) and 3 competing distributors (Longden,Northeast Flooring, Slayton).

Pools of hypervisors within the cloud operational system can support large numbers of virtual machines and the ability to scale services up and down according to customers' varying requirements.\r\nTypically IaaS solutions involve the use of a cloud orchestration technology like Open Stack, Apache Cloudstack or Open Nebula. This manages the creation of a virtual machine and decides on which hypervisor (i.e. physical host) to start it, enables VM migration features between hosts, allocates storage volumes and attaches them to VMs, usage information for billing and lots more.\r\nAn alternative to hypervisors are Linux containers, which run in isolated partitions of a single Linux kernel running directly on the physical hardware. Linux cgroups and namespaces are the underlying Linux kernel technologies used to isolate, secure and manage the containers. Containerisation offers higher performance than virtualization, because there is no hypervisor overhead. Also, container capacity auto-scales dynamically with computing load, which eliminates the problem of over-provisioning and enables usage-based billing.\r\nIaaS clouds often offer additional resources such as a virtual-machine disk-image library, raw block storage, file or object storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles.\r\nAccording to the Internet Engineering Task Force (IETF), the most basic cloud-service model is that of providers offering IT infrastructure – virtual machines and other resources – as a service to subscribers.\r\nIaaS cloud providers supply these resources on-demand from their large pools of equipment installed in data centers. For wide-area connectivity, customers can use either the Internet or carrier clouds (dedicated virtual private networks). To deploy their applications, cloud users install operating-system images and their application software on the cloud infrastructure. In this model, the cloud user patches and maintains the operating systems and the application software. Cloud infrastructure providers typically bill IaaS services on a utility computing basis: cost reflects the amount of resources allocated and consumed.","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: bold; \">Infrastructure as a Service Benefits&nbsp;</span></h1>\r\n<span style=\"font-weight: bold; \">Cost savings:</span> An obvious benefit of moving to the managed IaaS model is lower infrastructure costs. No longer do organizations have the responsibility of ensuring uptime, maintaining hardware and networking equipment, or replacing old equipment. IaaS&nbsp; technology also saves enterprises from having to buy more capacity to deal with sudden business spikes. Organizations with a smaller IT infrastructure generally require a smaller IT staff as well. The pay-as-you-go model also provides significant cost savings. \r\n<span style=\"font-weight: bold; \">Scalability and flexibility:</span> One of the greatest benefits of IaaS is the ability to scale up and down quickly in response to an enterprise’s requirements. Infrastructure as a Service providers generally have the latest, most powerful storage, servers and networking technology to accommodate the needs of their customers. This on-demand scalability provides added flexibility and greater agility to respond to changing opportunities and requirements. \r\n<span style=\"font-weight: bold; \">Faster time to market:</span> Competition is strong in every sector, and time to market is one of the best ways to beat the competition. Because IaaS vendors elasticity and scalability, organizations can ramp up and get the job done (and the product or service to market) more rapidly.\r\n<span style=\"font-weight: bold; \">Support for DR, BC and high availability:</span> While every enterprise has some type of disaster recovery plan, the technology behind those plans is often expensive and unwieldy. Organizations with several disparate locations often have different disaster recovery and business continuity plans and technologies, making management virtually impossible.\r\n<span style=\"font-weight: bold; \">Focus on business growth:</span> Time, money and energy spent making technology decisions and hiring staff to manage and maintain the technology infrastructure is time not spent on growing the business. By moving infrastructure to a global infrastructure services, organizations can focus their time and resources where they belong, on developing innovations in applications and solutions.\r\n<h1 class=\"align-center\">IaaS, PaaS and SaaS: What’s the Difference?</h1>\r\nPlatform as a Service (PaaS) is the next step up from IaaS products, where the provider also supplies the operating environment including the operating system, application services, middleware and other ‘runtimes’ for cloud users. It’s used for development environments where the business can focus on creating an app but wants someone else to maintain the deployment platform. It means you have much simpler workloads but you can’t necessarily be as flexible as you want.\r\nAt the highest level of orchestration is Software as a Service. In SaaS infrastructure applications are accessed on demand. Here you just open your browser and go, consuming software rather than installing and running it. A user simply logs on to access the provider’s application. Users can decide how the app will work but pretty much everything else is the responsibility of the software provider.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_IaaS.png"}],"additionalInfo":{"budgetNotExceeded":"","functionallyTaskAssignment":"","projectWasPut":"","price":0,"source":{"url":"file:///C:/Users/User/Downloads/_content_dam_digitalmarketing_vmware_en_pdf_customers_vmw-helvetia-casestudy.pdf","title":"Web-site of vendor"}},"comments":[],"referencesCount":0},"vmware-vrealize-vmware-vsphere-for-ukrtelecom":{"id":898,"title":"VMware vRealize, VMware vSphere for Ukrtelecom","description":"Description is not ready yet","alias":"vmware-vrealize-vmware-vsphere-for-ukrtelecom","roi":0,"seo":{"title":"VMware vRealize, VMware vSphere for Ukrtelecom","keywords":"","description":"Description is not ready yet","og:title":"VMware vRealize, VMware vSphere for Ukrtelecom","og:description":"Description is not ready yet"},"deal_info":"","user":{"id":2892,"title":"Ukrtelecom","logoURL":"https://old.roi4cio.com/uploads/roi/company/Ukrtelekom.jpg","alias":"ukrtelekom","address":"","roles":[],"description":"Ukrtelecom Joint Stock Company is one of the largest companies in Ukraine which provides a full range of telecommunication services in all regions of the country.\r\nThe company holds particularly strong position in the Internet and fixed telephony market.

To fully grasp how VMs work, it’s important to first understand how computer software and hardware are typically integrated by an operating system.\r\n&quot;The cloud&quot; refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies don't have to manage physical servers themselves or run software applications on their own machines.\r\nThe cloud enables users to access the same files and applications from almost any device, because the computing and storage take place on servers in a data center, instead of locally on the user device. This is why a user can log into their Instagram account on a new phone after their old phone breaks and still find their old account in place, with all their photos, videos, and conversation history. It works the same way with cloud email providers like Gmail or Microsoft Office 365, and with cloud storage providers like Dropbox or Google Drive.\r\nFor businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact on small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access the same files and applications from any location.\r\nSeveral cloud providers offer virtual machines to their customers. These virtual machines typically live on powerful servers that can act as a host to multiple VMs and can be used for a variety of reasons that wouldn’t be practical with a locally-hosted VM. These include:\r\n<ul><li>Running SaaS applications - Software-as-a-Service, or SaaS for short, is a cloud-based method of providing software to users. SaaS users subscribe to an application rather than purchasing it once and installing it. These applications are generally served to the user over the Internet. Often, it is virtual machines in the cloud that are doing the computation for SaaS applications as well as delivering them to users. If the cloud provider has a geographically distributed network edge, then the application will run closer to the user, resulting in faster performance.</li><li>Backing up data - Cloud-based VM services are very popular for backing up data because the data can be accessed from anywhere. Plus, cloud VMs provide better redundancy, require less maintenance, and generally scale better than physical data centers. (For example, it’s generally fairly easy to buy an extra gigabyte of storage space from a cloud VM provider, but much more difficult to build a new local data server for that extra gigabyte of data.)</li><li>Hosting services like email and access management - Hosting these services on cloud VMs is generally faster and more cost-effective, and helps minimize maintenance and offload security concerns as well.</li></ul>","materialsDescription":"What is an operating system?\r\nTraditional computers are built out of physical hardware, including hard disk drives, processor chips, RAM, etc. In order to utilize this hardware, computers rely on a type of software known as an operating system (OS). Some common examples of OSes are Mac OSX, Microsoft Windows, Linux, and Android.\r\nThe OS is what manages the computer’s hardware in ways that are useful to the user. For example, if the user wants to access the Internet, the OS directs the network interface card to make the connection. If the user wants to download a file, the OS will partition space on the hard drive for that file. The OS also runs and manages other pieces of software. For example, it can run a web browser and provide the browser with enough random access memory (RAM) to operate smoothly. Typically, operating systems exist within a physical computer at a one-to-one ratio; for each machine, there is a single OS managing its physical resources.\r\n<span style=\"font-weight: bold;\">Can you have two or more operating systems on one computer?</span>\r\nSome users want to be able to run multiple operating systems simultaneously on one computer, either for testing or one of the other reasons listed in the section below. This can be achieved through a process called virtualization. In virtualization, a piece of software behaves as if it were an independent computer. This piece of software is called a virtual machine, also known as a ‘guest’ computer. (The computer on which the VM is running is called the ‘host’.) The guest has an OS as well as its own virtual hardware.\r\n‘Virtual hardware’ may sound like a bit of an oxymoron, but it works by mapping to real hardware on the host computer. For example, the VM’s ‘hard drive’ is really just a file on the host computer’s hard drive. When the VM wants to save a new file, it actually has to communicate with the host OS, which will write this file to the host hard drive. Because virtual hardware must perform this added step of negotiating with the host to access hardware resources, virtual machines can’t run quite as fast as their host computers.\r\nWith virtualization, one computer can run two or more operating systems. The number of VMs that can run on one host is limited only by the host’s available resources. The user can run the OS of a VM in a window like any other program, or they can run it in fullscreen so that it looks and feels like a genuine host OS.\r\n <span style=\"font-weight: bold; \">What are virtual machines used for?</span>\r\nSome of the most popular reasons people run virtual machines include:\r\n<span style=\"font-weight: bold; \">Testing</span> - Oftentimes software developers want to be able to test their applications in different environments. They can use virtual machines to run their applications in various OSes on one computer. This is simpler and more cost-effective than having to test on several different physical machines.\r\n<span style=\"font-weight: bold; \">Running software designed for other OSes</span> - Although certain software applications are only available for a single platform, a VM can run software designed for a different OS. For example, a Mac user who wants to run software designed for Windows can run a Windows VM on their Mac host.\r\n<span style=\"font-weight: bold; \">Running outdated software</span> - Some pieces of older software can’t be run in modern OSes. Users who want to run these applications can run an old OS on a virtual machine.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Virtual_machine_and_cloud_system_software.png"},{"id":1,"title":"Desktop virtualization","alias":"desktop-virtualization","description":" Desktop virtualization is a virtualization technology that separates an individual's PC applications from his or her desktop. Virtualized desktops are generally hosted on a remote central server, rather than the hard drive of the personal computer. Because the client-server computing model is used in virtualizing desktops, desktop virtualization is also known as client virtualization.\r\nDesktop virtualization provides a way for users to maintain their individual desktops on a single, central server. The users may be connected to the central server through a LAN, WAN or over the Internet.\r\nDesktop virtualization has many benefits, including a lower total cost of ownership (TCO), increased security, reduced energy costs, reduced downtime and centralized management.\r\nLimitations of desktop virtualization include difficulty in maintenance and set up of printer drivers; increased downtime in case of network failures; complexity and costs involved in VDI deployment and security risks in the event of improper network management.<br /><br />","materialsDescription":" <span style=\"font-weight: bold; \">What are types of desktop virtualization technologies?</span>\r\nHost-based forms of desktop virtualization require that users view and interact with their virtual desktops over a network by using a remote display protocol. Because processing takes place in a data center, client devices can be traditional PCs, but also thin clients, zero clients, smartphones and tablets. Examples of host-based desktop virtualization technology include:\r\n<span style=\"font-weight: bold; \">Host-based virtual machines:</span> Each user connects to an individual VM that is hosted in a data center. The user may connect to the same VM every time, allowing for personalization (known as a persistent desktop), or be given a fresh VM at each login (a nonpersistent desktop).\r\n<span style=\"font-weight: bold; \">Shared hosted:</span> Users connect to a shared desktop that runs on a server.

This is useful for groups of desktops that use the same disk image. OS image streaming, also known as remote desktop virtualization, requires a constant network connection in order to function.\r\n<span style=\"font-weight: bold; \">Client-based virtual machines:</span> A VM runs on a fully functional PC, with a hypervisor in place.

As a result, public PaaS and IaaS (infrastructure as a service) run together, with PaaS operating on top of a vendor's IaaS infrastructure while leveraging the public cloud. \r\n<ul><li><span style=\"font-weight: bold; \">Private PaaS</span></li></ul>\r\nA private PaaS is usually delivered as an appliance or software within the user's firewall which is frequently maintained in the company's on-premises data center. A private PaaS software can be developed on any type of infrastructure and can work within the company's specific private cloud. Private PaaS allows an organization to better serve developers, improve the use of internal resources and reduce the costly cloud sprawl that many companies face.\r\n<ul><li><span style=\"font-weight: bold; \">Hybrid PaaS </span></li></ul>\r\nCombines public PaaS and private PaaS to provide companies with the flexibility of infinite capacity provided by a public PaaS model and the cost efficiencies of owning an internal infrastructure in private PaaS. Hybrid PaaS utilizes a hybrid cloud.\r\n<ul><li><span style=\"font-weight: bold; \">Communication PaaS </span></li></ul>\r\nCPaaS is a cloud-based platform that allows developers to add real-time communications to their apps without the need for back-end infrastructure and interfaces. Normally, real-time communications occur in apps that are built specifically for these functions. Examples include Skype, FaceTime, WhatsApp and the traditional phone. CPaaS provides a complete development framework for the creation of real-time communications features without the necessity of a developer building their own framework.\r\n<ul><li><span style=\"font-weight: bold; \">Mobile PaaS</span> </li></ul>\r\nMPaaS is the use of a paid integrated development environment for the configuration of mobile apps.

Pools of hypervisors within the cloud operational system can support large numbers of virtual machines and the ability to scale services up and down according to customers' varying requirements.\r\nTypically IaaS solutions involve the use of a cloud orchestration technology like Open Stack, Apache Cloudstack or Open Nebula. This manages the creation of a virtual machine and decides on which hypervisor (i.e. physical host) to start it, enables VM migration features between hosts, allocates storage volumes and attaches them to VMs, usage information for billing and lots more.\r\nAn alternative to hypervisors are Linux containers, which run in isolated partitions of a single Linux kernel running directly on the physical hardware. Linux cgroups and namespaces are the underlying Linux kernel technologies used to isolate, secure and manage the containers. Containerisation offers higher performance than virtualization, because there is no hypervisor overhead. Also, container capacity auto-scales dynamically with computing load, which eliminates the problem of over-provisioning and enables usage-based billing.\r\nIaaS clouds often offer additional resources such as a virtual-machine disk-image library, raw block storage, file or object storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles.\r\nAccording to the Internet Engineering Task Force (IETF), the most basic cloud-service model is that of providers offering IT infrastructure – virtual machines and other resources – as a service to subscribers.\r\nIaaS cloud providers supply these resources on-demand from their large pools of equipment installed in data centers. For wide-area connectivity, customers can use either the Internet or carrier clouds (dedicated virtual private networks). To deploy their applications, cloud users install operating-system images and their application software on the cloud infrastructure. In this model, the cloud user patches and maintains the operating systems and the application software. Cloud infrastructure providers typically bill IaaS services on a utility computing basis: cost reflects the amount of resources allocated and consumed.","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: bold; \">Infrastructure as a Service Benefits&nbsp;</span></h1>\r\n<span style=\"font-weight: bold; \">Cost savings:</span> An obvious benefit of moving to the managed IaaS model is lower infrastructure costs. No longer do organizations have the responsibility of ensuring uptime, maintaining hardware and networking equipment, or replacing old equipment. IaaS&nbsp; technology also saves enterprises from having to buy more capacity to deal with sudden business spikes. Organizations with a smaller IT infrastructure generally require a smaller IT staff as well. The pay-as-you-go model also provides significant cost savings. \r\n<span style=\"font-weight: bold; \">Scalability and flexibility:</span> One of the greatest benefits of IaaS is the ability to scale up and down quickly in response to an enterprise’s requirements. Infrastructure as a Service providers generally have the latest, most powerful storage, servers and networking technology to accommodate the needs of their customers. This on-demand scalability provides added flexibility and greater agility to respond to changing opportunities and requirements. \r\n<span style=\"font-weight: bold; \">Faster time to market:</span> Competition is strong in every sector, and time to market is one of the best ways to beat the competition. Because IaaS vendors elasticity and scalability, organizations can ramp up and get the job done (and the product or service to market) more rapidly.\r\n<span style=\"font-weight: bold; \">Support for DR, BC and high availability:</span> While every enterprise has some type of disaster recovery plan, the technology behind those plans is often expensive and unwieldy. Organizations with several disparate locations often have different disaster recovery and business continuity plans and technologies, making management virtually impossible.\r\n<span style=\"font-weight: bold; \">Focus on business growth:</span> Time, money and energy spent making technology decisions and hiring staff to manage and maintain the technology infrastructure is time not spent on growing the business. By moving infrastructure to a global infrastructure services, organizations can focus their time and resources where they belong, on developing innovations in applications and solutions.\r\n<h1 class=\"align-center\">IaaS, PaaS and SaaS: What’s the Difference?</h1>\r\nPlatform as a Service (PaaS) is the next step up from IaaS products, where the provider also supplies the operating environment including the operating system, application services, middleware and other ‘runtimes’ for cloud users. It’s used for development environments where the business can focus on creating an app but wants someone else to maintain the deployment platform. It means you have much simpler workloads but you can’t necessarily be as flexible as you want.\r\nAt the highest level of orchestration is Software as a Service. In SaaS infrastructure applications are accessed on demand. Here you just open your browser and go, consuming software rather than installing and running it. A user simply logs on to access the provider’s application. Users can decide how the app will work but pretty much everything else is the responsibility of the software provider.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_IaaS.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]}],"countries":[{"id":217,"title":"Ukraine","name":"UKR"}],"startDate":"0000-00-00","endDate":"0000-00-00","dealDate":"0000-00-00","price":0,"status":"finished","statusLabel":"Finished","isImplementation":true,"isAgreement":false,"confirmed":1,"implementationDetails":{"businessObjectives":{"id":14,"title":"Business objectives","translationKey":"businessObjectives","options":[{"id":4,"title":"Reduce Costs"},{"id":5,"title":"Enhance Staff Productivity"},{"id":6,"title":"Ensure Security and Business Continuity"},{"id":10,"title":"Ensure Compliance"},{"id":254,"title":"Centralize management"}]},"businessProcesses":{"id":11,"title":"Business process","translationKey":"businessProcesses","options":[{"id":177,"title":"Decentralized IT systems"},{"id":178,"title":"No control over data access"},{"id":400,"title":"High costs"},{"id":401,"title":"No control over implementation"},{"id":393,"title":"Complex and non-transparent business processes"},{"id":373,"title":"IT infrastructure does not meet business tasks"},{"id":370,"title":"No automated business processes"},{"id":348,"title":"No centralized control over IT systems"}]}},"categories":[{"id":2,"title":"Virtual machine and cloud system software","alias":"virtual-machine-and-cloud-system-software","description":" A virtual machine (VM) is a software-based computer that exists within another computer’s operating system, often used for the purposes of testing, backing up data, or running SaaS applications. To fully grasp how VMs work, it’s important to first understand how computer software and hardware are typically integrated by an operating system.\r\n&quot;The cloud&quot; refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies don't have to manage physical servers themselves or run software applications on their own machines.\r\nThe cloud enables users to access the same files and applications from almost any device, because the computing and storage take place on servers in a data center, instead of locally on the user device. This is why a user can log into their Instagram account on a new phone after their old phone breaks and still find their old account in place, with all their photos, videos, and conversation history. It works the same way with cloud email providers like Gmail or Microsoft Office 365, and with cloud storage providers like Dropbox or Google Drive.\r\nFor businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact on small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access the same files and applications from any location.\r\nSeveral cloud providers offer virtual machines to their customers. These virtual machines typically live on powerful servers that can act as a host to multiple VMs and can be used for a variety of reasons that wouldn’t be practical with a locally-hosted VM. These include:\r\n<ul><li>Running SaaS applications - Software-as-a-Service, or SaaS for short, is a cloud-based method of providing software to users. SaaS users subscribe to an application rather than purchasing it once and installing it. These applications are generally served to the user over the Internet. Often, it is virtual machines in the cloud that are doing the computation for SaaS applications as well as delivering them to users. If the cloud provider has a geographically distributed network edge, then the application will run closer to the user, resulting in faster performance.</li><li>Backing up data - Cloud-based VM services are very popular for backing up data because the data can be accessed from anywhere. Plus, cloud VMs provide better redundancy, require less maintenance, and generally scale better than physical data centers. (For example, it’s generally fairly easy to buy an extra gigabyte of storage space from a cloud VM provider, but much more difficult to build a new local data server for that extra gigabyte of data.)</li><li>Hosting services like email and access management - Hosting these services on cloud VMs is generally faster and more cost-effective, and helps minimize maintenance and offload security concerns as well.</li></ul>","materialsDescription":"What is an operating system?\r\nTraditional computers are built out of physical hardware, including hard disk drives, processor chips, RAM, etc. In order to utilize this hardware, computers rely on a type of software known as an operating system (OS). Some common examples of OSes are Mac OSX, Microsoft Windows, Linux, and Android.\r\nThe OS is what manages the computer’s hardware in ways that are useful to the user. For example, if the user wants to access the Internet, the OS directs the network interface card to make the connection. If the user wants to download a file, the OS will partition space on the hard drive for that file. The OS also runs and manages other pieces of software. For example, it can run a web browser and provide the browser with enough random access memory (RAM) to operate smoothly. Typically, operating systems exist within a physical computer at a one-to-one ratio; for each machine, there is a single OS managing its physical resources.\r\n<span style=\"font-weight: bold;\">Can you have two or more operating systems on one computer?</span>\r\nSome users want to be able to run multiple operating systems simultaneously on one computer, either for testing or one of the other reasons listed in the section below. This can be achieved through a process called virtualization. In virtualization, a piece of software behaves as if it were an independent computer. This piece of software is called a virtual machine, also known as a ‘guest’ computer. (The computer on which the VM is running is called the ‘host’.) The guest has an OS as well as its own virtual hardware.\r\n‘Virtual hardware’ may sound like a bit of an oxymoron, but it works by mapping to real hardware on the host computer. For example, the VM’s ‘hard drive’ is really just a file on the host computer’s hard drive. When the VM wants to save a new file, it actually has to communicate with the host OS, which will write this file to the host hard drive. Because virtual hardware must perform this added step of negotiating with the host to access hardware resources, virtual machines can’t run quite as fast as their host computers.\r\nWith virtualization, one computer can run two or more operating systems. The number of VMs that can run on one host is limited only by the host’s available resources. The user can run the OS of a VM in a window like any other program, or they can run it in fullscreen so that it looks and feels like a genuine host OS.\r\n <span style=\"font-weight: bold; \">What are virtual machines used for?</span>\r\nSome of the most popular reasons people run virtual machines include:\r\n<span style=\"font-weight: bold; \">Testing</span> - Oftentimes software developers want to be able to test their applications in different environments. They can use virtual machines to run their applications in various OSes on one computer. This is simpler and more cost-effective than having to test on several different physical machines.\r\n<span style=\"font-weight: bold; \">Running software designed for other OSes</span> - Although certain software applications are only available for a single platform, a VM can run software designed for a different OS. For example, a Mac user who wants to run software designed for Windows can run a Windows VM on their Mac host.\r\n<span style=\"font-weight: bold; \">Running outdated software</span> - Some pieces of older software can’t be run in modern OSes.

Because the client-server computing model is used in virtualizing desktops, desktop virtualization is also known as client virtualization.\r\nDesktop virtualization provides a way for users to maintain their individual desktops on a single, central server. The users may be connected to the central server through a LAN, WAN or over the Internet.\r\nDesktop virtualization has many benefits, including a lower total cost of ownership (TCO), increased security, reduced energy costs, reduced downtime and centralized management.\r\nLimitations of desktop virtualization include difficulty in maintenance and set up of printer drivers; increased downtime in case of network failures; complexity and costs involved in VDI deployment and security risks in the event of improper network management.<br /><br />","materialsDescription":" <span style=\"font-weight: bold; \">What are types of desktop virtualization technologies?</span>\r\nHost-based forms of desktop virtualization require that users view and interact with their virtual desktops over a network by using a remote display protocol. Because processing takes place in a data center, client devices can be traditional PCs, but also thin clients, zero clients, smartphones and tablets. Examples of host-based desktop virtualization technology include:\r\n<span style=\"font-weight: bold; \">Host-based virtual machines:</span> Each user connects to an individual VM that is hosted in a data center. The user may connect to the same VM every time, allowing for personalization (known as a persistent desktop), or be given a fresh VM at each login (a nonpersistent desktop).\r\n<span style=\"font-weight: bold; \">Shared hosted:</span> Users connect to a shared desktop that runs on a server. Microsoft Remote Desktop Services, formerly Terminal Services, takes this client-server approach. Users may also connect to individual applications running on a server; this technology is an example of application virtualization.\r\n<span style=\"font-weight: bold; \">Host-based physical machines:</span> The operating system runs directly on another device's physical hardware.\r\nClient virtualization requires processing to occur on local hardware; the use of thin clients, zero clients and mobile devices is not possible. These types of desktop virtualization include:\r\n<span style=\"font-weight: bold; \">OS image streaming:</span> The operating system runs on local hardware, but it boots to a remote disk image across the network. This is useful for groups of desktops that use the same disk image. OS image streaming, also known as remote desktop virtualization, requires a constant network connection in order to function.\r\n<span style=\"font-weight: bold; \">Client-based virtual machines:</span> A VM runs on a fully functional PC, with a hypervisor in place. Client-based virtual machines can be managed by regularly syncing the disk image with a server, but a constant network connection is not necessary in order for them to function.\r\n<span style=\"font-weight: bold;\">Desktop virtualization vs. virtual desktop infrastructure</span>\r\nThe terms <span style=\"font-style: italic;\">desktop virtualization</span> and virtual desktop infrastructure (VDI) are often used interchangeably, but they are not the same. While VDI is a type of desktop virtualization, not all desktop virtualization uses VDI.\r\nVDI refers to the use of host-based VMs to deliver virtual desktops, which emerged in 2006 as an alternative to Terminal Services and Citrix's client-server approach to desktop virtualization technology. Other types of desktop virtualization -- including the shared hosted model, host-based physical machines and all methods of client virtualization -- are not examples of VDI.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Desktop_virtualization.png"},{"id":51,"title":"PaaS - Platform as a service","alias":"paas-platform-as-a-service","description":"<span style=\"font-weight: bold; \">Platform as a Service (PaaS)</span> or <span style=\"font-weight: bold; \">Application Platform as a Service (aPaaS)</span> or <span style=\"font-weight: bold; \">platform-based service</span> is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.\r\n<span style=\"font-weight: bold; \">PaaS can be delivered in three ways:</span>\r\n<span style=\"font-weight: bold;\">As a public cloud service</span> from a provider, where the consumer controls software deployment with minimal configuration options, and the provider provides the networks, servers, storage, operating system (OS), middleware (e.g. Java runtime, .NET runtime, integration, etc.), database and other services to host the consumer's application.\r\n<span style=\"font-weight: bold;\">As a private service</span> (software or appliance) behind a firewall.\r\n<span style=\"font-weight: bold;\">As software</span> deployed on a public infrastructure as a service.\r\n<span style=\"color: rgb(97, 97, 97); \">The original intent of PaaS technology was to simplify the code-writing process for developers, with the infrastructure and operations handled by the PaaS provider. Originally, all PaaSes were in the public cloud. Because many companies did not want to have everything in the public cloud, private and hybrid PaaS options (managed by internal IT departments) were created.</span>\r\n<span style=\"color: rgb(97, 97, 97); \">PaaS provides an environment for developers and companies to create, host and deploy applications, saving developers from the complexities of the infrastructure side (setting up, configuring and managing elements such as servers and databases).</span>\r\n<span style=\"color: rgb(97, 97, 97); \">PaaS products can improve the speed of developing an app, and allow the consumer to focus on the application itself. With PaaS, the consumer manages applications and data, while the provider (in public PaaS) or IT department (in private PaaS) manages runtime, middleware, operating system, virtualization, servers, storage and networking.</span>\r\n<span style=\"color: rgb(97, 97, 97); \">PaaS offerings may also include facilities for application design, application development, testing and deployment, as well as services such as team collaboration, web service integration, and marshalling, database integration, security, scalability, storage, persistence, state management, application versioning, application instrumentation, and developer community facilitation. Besides the service engineering aspects, PaaS solutions include mechanisms for service management, such as monitoring, workflow management, discovery and reservation.</span>\r\nThere are various types of PaaS providers. All offer application hosting and a deployment environment, along with various integrated services. Services offer varying levels of scalability and maintenance. Developers can write an application and upload it to a PaaS platform that supports their software language of choice, and the application runs on that PaaS.","materialsDescription":"<h1 class=\"align-center\">How PaaS works</h1>\r\n<p class=\"align-left\">PaaS does not replace a company's entire IT infrastructure for software development. It is provided through a cloud service provider's hosted infrastructure with users most frequently accessing the offerings through a web browser. PaaS can be delivered through public, private and hybrid clouds to deliver services such as application hosting and Java development.</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold; \">Other PaaS services include:</span></p>\r\n<ul><li>Development team collaboration</li><li>Application design and development</li><li>Application testing and deployment</li><li>Web service integration</li><li>Information security</li><li>Database integration</li></ul>\r\n<p class=\"align-left\">Users pay for PaaS on a per-use basis. However, different platform as a service providers charge a flat monthly fee for access to the platform and its applications.</p>\r\n<h1 class=\"align-center\">What are the types of PaaS?</h1>\r\n<ul><li><span style=\"font-weight: bold; \">Public PaaS</span></li></ul>\r\nA public PaaS allows the user to control software deployment while the cloud provider manages the delivery of all other major IT components necessary to the hosting of applications, including operating systems, databases, servers and storage system networks. \r\nPublic PaaS vendors offer middleware that enables developers to set up, configure and control servers and databases without the necessity of setting up the infrastructure side of things. As a result, public PaaS and IaaS (infrastructure as a service) run together, with PaaS operating on top of a vendor's IaaS infrastructure while leveraging the public cloud. \r\n<ul><li><span style=\"font-weight: bold; \">Private PaaS</span></li></ul>\r\nA private PaaS is usually delivered as an appliance or software within the user's firewall which is frequently maintained in the company's on-premises data center. A private PaaS software can be developed on any type of infrastructure and can work within the company's specific private cloud. Private PaaS allows an organization to better serve developers, improve the use of internal resources and reduce the costly cloud sprawl that many companies face.\r\n<ul><li><span style=\"font-weight: bold; \">Hybrid PaaS </span></li></ul>\r\nCombines public PaaS and private PaaS to provide companies with the flexibility of infinite capacity provided by a public PaaS model and the cost efficiencies of owning an internal infrastructure in private PaaS. Hybrid PaaS utilizes a hybrid cloud.\r\n<ul><li><span style=\"font-weight: bold; \">Communication PaaS </span></li></ul>\r\nCPaaS is a cloud-based platform that allows developers to add real-time communications to their apps without the need for back-end infrastructure and interfaces. Normally, real-time communications occur in apps that are built specifically for these functions. Examples include Skype, FaceTime, WhatsApp and the traditional phone. CPaaS provides a complete development framework for the creation of real-time communications features without the necessity of a developer building their own framework.\r\n<ul><li><span style=\"font-weight: bold; \">Mobile PaaS</span> </li></ul>\r\nMPaaS is the use of a paid integrated development environment for the configuration of mobile apps. In an mPaaS, coding skills are not required. MPaaS is delivered through a web browser and typically supports public cloud, private cloud and on-premises storage. The service is usually leased with pricing per month, varying according to the number of included devices and supported features.\r\n<ul><li><span style=\"font-weight: bold; \">Open PaaS</span></li></ul>\r\nIt is a free, open source, business-oriented collaboration platform that is attractive on all devices and provides useful web apps, including calendar, contacts and mail applications. OpenPaaS was designed to allow users to quickly deploy new applications with the goal of developing a PaaS technology that is committed to enterprise collaborative applications, specifically those deployed on hybrid clouds.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/PaaS_-_Platform_as_a_service.png"},{"id":39,"title":"IaaS - Infrastructure as a Service","alias":"iaas-infrastructure-as-a-service","description":"<span style=\"font-weight: bold;\">Infrastructure as a service</span> (IaaS) are online services that provide high-level APIs used to dereference various low-level details of underlying network infrastructure like physical computing resources, location, data partitioning, scaling, security, backup etc. A hypervisor, such as Xen, Oracle VirtualBox, Oracle VM, KVM, VMware ESX/ESXi, or Hyper-V, LXD, runs the virtual machines as guests. Pools of hypervisors within the cloud operational system can support large numbers of virtual machines and the ability to scale services up and down according to customers' varying requirements.\r\nTypically IaaS solutions involve the use of a cloud orchestration technology like Open Stack, Apache Cloudstack or Open Nebula. This manages the creation of a virtual machine and decides on which hypervisor (i.e. physical host) to start it, enables VM migration features between hosts, allocates storage volumes and attaches them to VMs, usage information for billing and lots more.\r\nAn alternative to hypervisors are Linux containers, which run in isolated partitions of a single Linux kernel running directly on the physical hardware. Linux cgroups and namespaces are the underlying Linux kernel technologies used to isolate, secure and manage the containers. Containerisation offers higher performance than virtualization, because there is no hypervisor overhead. Also, container capacity auto-scales dynamically with computing load, which eliminates the problem of over-provisioning and enables usage-based billing.\r\nIaaS clouds often offer additional resources such as a virtual-machine disk-image library, raw block storage, file or object storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles.\r\nAccording to the Internet Engineering Task Force (IETF), the most basic cloud-service model is that of providers offering IT infrastructure – virtual machines and other resources – as a service to subscribers.\r\nIaaS cloud providers supply these resources on-demand from their large pools of equipment installed in data centers. For wide-area connectivity, customers can use either the Internet or carrier clouds (dedicated virtual private networks). To deploy their applications, cloud users install operating-system images and their application software on the cloud infrastructure. In this model, the cloud user patches and maintains the operating systems and the application software. Cloud infrastructure providers typically bill IaaS services on a utility computing basis: cost reflects the amount of resources allocated and consumed.","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: bold; \">Infrastructure as a Service Benefits&nbsp;</span></h1>\r\n<span style=\"font-weight: bold; \">Cost savings:</span> An obvious benefit of moving to the managed IaaS model is lower infrastructure costs. No longer do organizations have the responsibility of ensuring uptime, maintaining hardware and networking equipment, or replacing old equipment. IaaS&nbsp; technology also saves enterprises from having to buy more capacity to deal with sudden business spikes. Organizations with a smaller IT infrastructure generally require a smaller IT staff as well. The pay-as-you-go model also provides significant cost savings. \r\n<span style=\"font-weight: bold; \">Scalability and flexibility:</span> One of the greatest benefits of IaaS is the ability to scale up and down quickly in response to an enterprise’s requirements. Infrastructure as a Service providers generally have the latest, most powerful storage, servers and networking technology to accommodate the needs of their customers. This on-demand scalability provides added flexibility and greater agility to respond to changing opportunities and requirements. \r\n<span style=\"font-weight: bold; \">Faster time to market:</span> Competition is strong in every sector, and time to market is one of the best ways to beat the competition. Because IaaS vendors elasticity and scalability, organizations can ramp up and get the job done (and the product or service to market) more rapidly.\r\n<span style=\"font-weight: bold; \">Support for DR, BC and high availability:</span> While every enterprise has some type of disaster recovery plan, the technology behind those plans is often expensive and unwieldy. Organizations with several disparate locations often have different disaster recovery and business continuity plans and technologies, making management virtually impossible.\r\n<span style=\"font-weight: bold; \">Focus on business growth:</span> Time, money and energy spent making technology decisions and hiring staff to manage and maintain the technology infrastructure is time not spent on growing the business. By moving infrastructure to a global infrastructure services, organizations can focus their time and resources where they belong, on developing innovations in applications and solutions.\r\n<h1 class=\"align-center\">IaaS, PaaS and SaaS: What’s the Difference?</h1>\r\nPlatform as a Service (PaaS) is the next step up from IaaS products, where the provider also supplies the operating environment including the operating system, application services, middleware and other ‘runtimes’ for cloud users. It’s used for development environments where the business can focus on creating an app but wants someone else to maintain the deployment platform. It means you have much simpler workloads but you can’t necessarily be as flexible as you want.\r\nAt the highest level of orchestration is Software as a Service. In SaaS infrastructure applications are accessed on demand. Here you just open your browser and go, consuming software rather than installing and running it. A user simply logs on to access the provider’s application. Users can decide how the app will work but pretty much everything else is the responsibility of the software provider.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_IaaS.png"}],"additionalInfo":{"budgetNotExceeded":"-1","functionallyTaskAssignment":"-1","projectWasPut":"-1","price":0,"source":{"url":"https://www.sibis.com.ua/project/postroenie-chastnogo-oblaka-vychislitelnyh-resursov/","title":"Supplier's web site"}},"comments":[],"referencesCount":0},"vmware-vsphere-enterprise-for-ukrainian-insurance-company":{"id":1007,"title":"VMWare vSphere Enterprise for Ukrainian insurance company","description":"<span style=\"font-style: italic; \">Description is not ready yet</span>","alias":"vmware-vsphere-enterprise-for-ukrainian-insurance-company","roi":0,"seo":{"title":"VMWare vSphere Enterprise for Ukrainian insurance company","keywords":"","description":"<span style=\"font-style: italic; \">Description is not ready yet</span>","og:title":"VMWare vSphere Enterprise for Ukrainian insurance company","og:description":"<span style=\"font-style: italic; \">Description is not ready yet</span>"},"deal_info":"","user":{},"supplier":{"id":2701,"title":"VERNA","logoURL":"https://old.roi4cio.com/uploads/roi/company/VERNA.png","alias":"verna","address":"","roles":[],"description":"VERNA is one of the leading IT Integrators, specializing in design, implementation and support of technical solutions, aimed to improve the efficiency of corporate IT systems, - both on-site and on a remote basis. <br />VERNA has spent more than 15 successful years of dynamic development in the MSP area, having implemented 150 + projects for national-wide companies at Ukrainian market as well as outsourced projects for clients from USA and Western Europe.<br />The main customers are large geographically distributed enterprises: banks, retails, industrial enterprises (BNP Paribas Group, GlobalLogic, Volksbank, Kraft, ArcelorMittal, UniCredit Bank and others).<br />Technical expertise and skills of VERNA team are proven by certificates and partnership statuses with Cisco, Microsoft, HP, IBM, APC, Oracle, VMware, Citrix, Intel, Dell, Siemens, Systemax, etc.<br />VERNA specializes in planning, implementation and support of the following solutions:<br />- Virtualization (VMware,Hyper-V, Citrix, Dockers)<br />- Infrastructure (MS Active Directory, Office 365, Azure, AWS amazon)<br />- VoIP (Cisco, asterisk/FreePBX/Elastix)<br />- Unified Communications (Webex, Big Blue Button, Lync, Exchange, SharePoint)<br />- Networking (Cisco, FortiNet, OpenVPN, CheckPoint)<br />- Server &amp; Storage (SAN, NAS, FAS)<br />- Business applications and databases (Microsoft, Oracle, IBM)<br />- VDI and terminal access solutions (Microsoft, VMware, Citrix)<br />- Storage virtualization (DataCore)<br />- DLP and Information Security (Antivirus systems, websence, Fortinet, DeviceLock e t.c.)<br />Source: https://www.linkedin.com/company/verna","companyTypes":[],"products":{},"vendoredProductsCount":0,"suppliedProductsCount":205,"supplierImplementations":[],"vendorImplementations":[],"userImplementations":[],"userImplementationsCount":0,"supplierImplementationsCount":41,"vendorImplementationsCount":0,"vendorPartnersCount":9,"supplierPartnersCount":0,"b4r":0,"categories":{},"companyUrl":"http://www.verna.ua/","countryCodes":[],"certifications":[],"isSeller":false,"isSupplier":false,"isVendor":false,"presenterCodeLng":"","seo":{"title":"VERNA","keywords":"solutions, infrastructure, providing, distributed, geographically, with, core, services","description":"VERNA is one of the leading IT Integrators, specializing in design, implementation and support of technical solutions, aimed to improve the efficiency of corporate IT systems, - both on-site and on a remote basis. <br />VERNA has spent more than 15 successful ","og:title":"VERNA","og:description":"VERNA is one of the leading IT Integrators, specializing in design, implementation and support of technical solutions, aimed to improve the efficiency of corporate IT systems, - both on-site and on a remote basis. <br />VERNA has spent more than 15 successful ","og:image":"https://old.roi4cio.com/uploads/roi/company/VERNA.png"},"eventUrl":""},"vendors":[{"id":168,"title":"VMware","logoURL":"https://old.roi4cio.com/uploads/roi/company/vmware_logo.png","alias":"vmware","address":"","roles":[],"description":"<span style=\"color: rgb(97, 97, 97); \">VMware was founded in 1998 and initially focused on the development of virtual machine technologies for standard computers.

To fully grasp how VMs work, it’s important to first understand how computer software and hardware are typically integrated by an operating system.\r\n&quot;The cloud&quot; refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies don't have to manage physical servers themselves or run software applications on their own machines.\r\nThe cloud enables users to access the same files and applications from almost any device, because the computing and storage take place on servers in a data center, instead of locally on the user device. This is why a user can log into their Instagram account on a new phone after their old phone breaks and still find their old account in place, with all their photos, videos, and conversation history. It works the same way with cloud email providers like Gmail or Microsoft Office 365, and with cloud storage providers like Dropbox or Google Drive.\r\nFor businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact on small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access the same files and applications from any location.\r\nSeveral cloud providers offer virtual machines to their customers. These virtual machines typically live on powerful servers that can act as a host to multiple VMs and can be used for a variety of reasons that wouldn’t be practical with a locally-hosted VM. These include:\r\n<ul><li>Running SaaS applications - Software-as-a-Service, or SaaS for short, is a cloud-based method of providing software to users. SaaS users subscribe to an application rather than purchasing it once and installing it. These applications are generally served to the user over the Internet. Often, it is virtual machines in the cloud that are doing the computation for SaaS applications as well as delivering them to users.

Some common examples of OSes are Mac OSX, Microsoft Windows, Linux, and Android.\r\nThe OS is what manages the computer’s hardware in ways that are useful to the user. For example, if the user wants to access the Internet, the OS directs the network interface card to make the connection. If the user wants to download a file, the OS will partition space on the hard drive for that file. The OS also runs and manages other pieces of software. For example, it can run a web browser and provide the browser with enough random access memory (RAM) to operate smoothly. Typically, operating systems exist within a physical computer at a one-to-one ratio; for each machine, there is a single OS managing its physical resources.\r\n<span style=\"font-weight: bold;\">Can you have two or more operating systems on one computer?</span>\r\nSome users want to be able to run multiple operating systems simultaneously on one computer, either for testing or one of the other reasons listed in the section below. This can be achieved through a process called virtualization. In virtualization, a piece of software behaves as if it were an independent computer. This piece of software is called a virtual machine, also known as a ‘guest’ computer. (The computer on which the VM is running is called the ‘host’.) The guest has an OS as well as its own virtual hardware.\r\n‘Virtual hardware’ may sound like a bit of an oxymoron, but it works by mapping to real hardware on the host computer. For example, the VM’s ‘hard drive’ is really just a file on the host computer’s hard drive. When the VM wants to save a new file, it actually has to communicate with the host OS, which will write this file to the host hard drive. Because virtual hardware must perform this added step of negotiating with the host to access hardware resources, virtual machines can’t run quite as fast as their host computers.\r\nWith virtualization, one computer can run two or more operating systems. The number of VMs that can run on one host is limited only by the host’s available resources. The user can run the OS of a VM in a window like any other program, or they can run it in fullscreen so that it looks and feels like a genuine host OS.\r\n <span style=\"font-weight: bold; \">What are virtual machines used for?</span>\r\nSome of the most popular reasons people run virtual machines include:\r\n<span style=\"font-weight: bold; \">Testing</span> - Oftentimes software developers want to be able to test their applications in different environments.

To fully grasp how VMs work, it’s important to first understand how computer software and hardware are typically integrated by an operating system.\r\n&quot;The cloud&quot; refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies don't have to manage physical servers themselves or run software applications on their own machines.\r\nThe cloud enables users to access the same files and applications from almost any device, because the computing and storage take place on servers in a data center, instead of locally on the user device. This is why a user can log into their Instagram account on a new phone after their old phone breaks and still find their old account in place, with all their photos, videos, and conversation history. It works the same way with cloud email providers like Gmail or Microsoft Office 365, and with cloud storage providers like Dropbox or Google Drive.\r\nFor businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact on small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access the same files and applications from any location.\r\nSeveral cloud providers offer virtual machines to their customers. These virtual machines typically live on powerful servers that can act as a host to multiple VMs and can be used for a variety of reasons that wouldn’t be practical with a locally-hosted VM. These include:\r\n<ul><li>Running SaaS applications - Software-as-a-Service, or SaaS for short, is a cloud-based method of providing software to users. SaaS users subscribe to an application rather than purchasing it once and installing it. These applications are generally served to the user over the Internet. Often, it is virtual machines in the cloud that are doing the computation for SaaS applications as well as delivering them to users. If the cloud provider has a geographically distributed network edge, then the application will run closer to the user, resulting in faster performance.</li><li>Backing up data - Cloud-based VM services are very popular for backing up data because the data can be accessed from anywhere.

To fully grasp how VMs work, it’s important to first understand how computer software and hardware are typically integrated by an operating system.\r\n&quot;The cloud&quot; refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies don't have to manage physical servers themselves or run software applications on their own machines.\r\nThe cloud enables users to access the same files and applications from almost any device, because the computing and storage take place on servers in a data center, instead of locally on the user device. This is why a user can log into their Instagram account on a new phone after their old phone breaks and still find their old account in place, with all their photos, videos, and conversation history. It works the same way with cloud email providers like Gmail or Microsoft Office 365, and with cloud storage providers like Dropbox or Google Drive.\r\nFor businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact on small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access the same files and applications from any location.\r\nSeveral cloud providers offer virtual machines to their customers. These virtual machines typically live on powerful servers that can act as a host to multiple VMs and can be used for a variety of reasons that wouldn’t be practical with a locally-hosted VM. These include:\r\n<ul><li>Running SaaS applications - Software-as-a-Service, or SaaS for short, is a cloud-based method of providing software to users. SaaS users subscribe to an application rather than purchasing it once and installing it. These applications are generally served to the user over the Internet. Often, it is virtual machines in the cloud that are doing the computation for SaaS applications as well as delivering them to users. If the cloud provider has a geographically distributed network edge, then the application will run closer to the user, resulting in faster performance.</li><li>Backing up data - Cloud-based VM services are very popular for backing up data because the data can be accessed from anywhere. Plus, cloud VMs provide better redundancy, require less maintenance, and generally scale better than physical data centers. (For example, it’s generally fairly easy to buy an extra gigabyte of storage space from a cloud VM provider, but much more difficult to build a new local data server for that extra gigabyte of data.)</li><li>Hosting services like email and access management - Hosting these services on cloud VMs is generally faster and more cost-effective, and helps minimize maintenance and offload security concerns as well.</li></ul>","materialsDescription":"What is an operating system?\r\nTraditional computers are built out of physical hardware, including hard disk drives, processor chips, RAM, etc. In order to utilize this hardware, computers rely on a type of software known as an operating system (OS). Some common examples of OSes are Mac OSX, Microsoft Windows, Linux, and Android.\r\nThe OS is what manages the computer’s hardware in ways that are useful to the user. For example, if the user wants to access the Internet, the OS directs the network interface card to make the connection. If the user wants to download a file, the OS will partition space on the hard drive for that file. The OS also runs and manages other pieces of software. For example, it can run a web browser and provide the browser with enough random access memory (RAM) to operate smoothly. Typically, operating systems exist within a physical computer at a one-to-one ratio; for each machine, there is a single OS managing its physical resources.\r\n<span style=\"font-weight: bold;\">Can you have two or more operating systems on one computer?</span>\r\nSome users want to be able to run multiple operating systems simultaneously on one computer, either for testing or one of the other reasons listed in the section below. This can be achieved through a process called virtualization. In virtualization, a piece of software behaves as if it were an independent computer. This piece of software is called a virtual machine, also known as a ‘guest’ computer. (The computer on which the VM is running is called the ‘host’.) The guest has an OS as well as its own virtual hardware.\r\n‘Virtual hardware’ may sound like a bit of an oxymoron, but it works by mapping to real hardware on the host computer. For example, the VM’s ‘hard drive’ is really just a file on the host computer’s hard drive. When the VM wants to save a new file, it actually has to communicate with the host OS, which will write this file to the host hard drive. Because virtual hardware must perform this added step of negotiating with the host to access hardware resources, virtual machines can’t run quite as fast as their host computers.\r\nWith virtualization, one computer can run two or more operating systems. The number of VMs that can run on one host is limited only by the host’s available resources. The user can run the OS of a VM in a window like any other program, or they can run it in fullscreen so that it looks and feels like a genuine host OS.\r\n <span style=\"font-weight: bold; \">What are virtual machines used for?</span>\r\nSome of the most popular reasons people run virtual machines include:\r\n<span style=\"font-weight: bold; \">Testing</span> - Oftentimes software developers want to be able to test their applications in different environments. They can use virtual machines to run their applications in various OSes on one computer. This is simpler and more cost-effective than having to test on several different physical machines.\r\n<span style=\"font-weight: bold; \">Running software designed for other OSes</span> - Although certain software applications are only available for a single platform, a VM can run software designed for a different OS. For example, a Mac user who wants to run software designed for Windows can run a Windows VM on their Mac host.\r\n<span style=\"font-weight: bold; \">Running outdated software</span> - Some pieces of older software can’t be run in modern OSes. Users who want to run these applications can run an old OS on a virtual machine.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Virtual_machine_and_cloud_system_software.png"},{"id":1,"title":"Desktop virtualization","alias":"desktop-virtualization","description":" Desktop virtualization is a virtualization technology that separates an individual's PC applications from his or her desktop.

To fully grasp how VMs work, it’s important to first understand how computer software and hardware are typically integrated by an operating system.\r\n&quot;The cloud&quot; refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies don't have to manage physical servers themselves or run software applications on their own machines.\r\nThe cloud enables users to access the same files and applications from almost any device, because the computing and storage take place on servers in a data center, instead of locally on the user device. This is why a user can log into their Instagram account on a new phone after their old phone breaks and still find their old account in place, with all their photos, videos, and conversation history. It works the same way with cloud email providers like Gmail or Microsoft Office 365, and with cloud storage providers like Dropbox or Google Drive.\r\nFor businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact on small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access the same files and applications from any location.\r\nSeveral cloud providers offer virtual machines to their customers. These virtual machines typically live on powerful servers that can act as a host to multiple VMs and can be used for a variety of reasons that wouldn’t be practical with a locally-hosted VM. These include:\r\n<ul><li>Running SaaS applications - Software-as-a-Service, or SaaS for short, is a cloud-based method of providing software to users. SaaS users subscribe to an application rather than purchasing it once and installing it. These applications are generally served to the user over the Internet. Often, it is virtual machines in the cloud that are doing the computation for SaaS applications as well as delivering them to users. If the cloud provider has a geographically distributed network edge, then the application will run closer to the user, resulting in faster performance.</li><li>Backing up data - Cloud-based VM services are very popular for backing up data because the data can be accessed from anywhere. Plus, cloud VMs provide better redundancy, require less maintenance, and generally scale better than physical data centers. (For example, it’s generally fairly easy to buy an extra gigabyte of storage space from a cloud VM provider, but much more difficult to build a new local data server for that extra gigabyte of data.)</li><li>Hosting services like email and access management - Hosting these services on cloud VMs is generally faster and more cost-effective, and helps minimize maintenance and offload security concerns as well.</li></ul>","materialsDescription":"What is an operating system?\r\nTraditional computers are built out of physical hardware, including hard disk drives, processor chips, RAM, etc. In order to utilize this hardware, computers rely on a type of software known as an operating system (OS). Some common examples of OSes are Mac OSX, Microsoft Windows, Linux, and Android.\r\nThe OS is what manages the computer’s hardware in ways that are useful to the user. For example, if the user wants to access the Internet, the OS directs the network interface card to make the connection. If the user wants to download a file, the OS will partition space on the hard drive for that file. The OS also runs and manages other pieces of software. For example, it can run a web browser and provide the browser with enough random access memory (RAM) to operate smoothly. Typically, operating systems exist within a physical computer at a one-to-one ratio; for each machine, there is a single OS managing its physical resources.\r\n<span style=\"font-weight: bold;\">Can you have two or more operating systems on one computer?</span>\r\nSome users want to be able to run multiple operating systems simultaneously on one computer, either for testing or one of the other reasons listed in the section below. This can be achieved through a process called virtualization. In virtualization, a piece of software behaves as if it were an independent computer. This piece of software is called a virtual machine, also known as a ‘guest’ computer. (The computer on which the VM is running is called the ‘host’.) The guest has an OS as well as its own virtual hardware.\r\n‘Virtual hardware’ may sound like a bit of an oxymoron, but it works by mapping to real hardware on the host computer. For example, the VM’s ‘hard drive’ is really just a file on the host computer’s hard drive. When the VM wants to save a new file, it actually has to communicate with the host OS, which will write this file to the host hard drive. Because virtual hardware must perform this added step of negotiating with the host to access hardware resources, virtual machines can’t run quite as fast as their host computers.\r\nWith virtualization, one computer can run two or more operating systems. The number of VMs that can run on one host is limited only by the host’s available resources. The user can run the OS of a VM in a window like any other program, or they can run it in fullscreen so that it looks and feels like a genuine host OS.\r\n <span style=\"font-weight: bold; \">What are virtual machines used for?</span>\r\nSome of the most popular reasons people run virtual machines include:\r\n<span style=\"font-weight: bold; \">Testing</span> - Oftentimes software developers want to be able to test their applications in different environments. They can use virtual machines to run their applications in various OSes on one computer. This is simpler and more cost-effective than having to test on several different physical machines.\r\n<span style=\"font-weight: bold; \">Running software designed for other OSes</span> - Although certain software applications are only available for a single platform, a VM can run software designed for a different OS. For example, a Mac user who wants to run software designed for Windows can run a Windows VM on their Mac host.\r\n<span style=\"font-weight: bold; \">Running outdated software</span> - Some pieces of older software can’t be run in modern OSes.
