Windows Server 2012 includes a Hyper-V module, which provides command-line access to all the functionality available in the GUI, as well functionality not available through the GUI. For more information about the Hyper-V module, see Hyper-V Module for Windows PowerShell.\r\nIf you use Server Manager to install the Hyper-V role, the management tools are included unless you specifically exclude them. If you use Windows PowerShell to install the Hyper-V role, the management tools are not included by default. To install the tools, use the parameter –IncludeManagementTools. For instructions about installing the Hyper-V role, see Install Hyper-V and create a virtual machine.\r\n\r\nOverview of Hyper-V\r\nApplies To: Windows Server 2008 R2\r\nHyper-V provides software infrastructure and basic management tools that you can use to create and manage a virtualized server computing environment. This virtualized environment can be used to address a variety of business goals aimed at improving efficiency and reducing costs. For example, a virtualized server environment can help you:\r\nReduce the costs of operating and maintaining physical servers by increasing your hardware utilization. You can reduce the amount of hardware needed to run your server workloads.\r\nIncrease development and test efficiency by reducing the amount of time it takes to set up hardware and software and reproduce test environments.\r\nImprove server availability without using as many physical computers as you would need in a failover configuration that uses only physical computers.\r\nSome ways Hyper-V can help you\r\nHyper-V can help you:\r\nEstablish or expand a private cloud environment. Provide more flexible, on-demand IT services by moving to or expanding your use of shared resources and adjust utilization as demand changes.\r\nUse your hardware more effectively. Consolidate servers and workloads onto fewer, more powerful physical computers to use less power and physical space.\r\nImprove business continuity. Minimize the impact of both scheduled and unscheduled downtime of your workloads.\r\nEstablish or expand a virtual desktop infrastructure (VDI). Use a centralized desktop strategy with VDI can help you increase business agility and data security, as well as simplify regulatory compliance and manage desktop operating systems and applications. Deploy Hyper-V and Remote Desktop Virtualization Host (RD Virtualization Host) on the same server to make personal virtual desktops or virtual desktop pools available to your users.\r\nMake development and test more efficient. Reproduce different computing environments without having to buy or maintain all the hardware you'd need if you only used physical systems.\r\nHyper-V and other virtualization products\r\nHyper-V in Windows and Windows Server replaces older hardware virtualization products, such as Microsoft Virtual PC, Microsoft Virtual Server, and Windows Virtual PC. Hyper-V offers networking, performance, storage and security features not available in these older products.\r\nHyper-V and most third-party virtualization applications that require the same processor features aren't compatible. That's because the processor features, known as hardware virtualization extensions, are designed to not be shared. For details, see Virtualization applications do not work together with Hyper-V, Device Guard, and Credential Guard.","shortDescription":"The Hyper-V role enables you to create and manage a virtualized computing environment by using virtualization technology that is built in to Windows Server.

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.

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":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. 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.

These core characteristics are volatility, mutability, accessibility, and addressability. For any particular implementation of any storage technology, the characteristics worth measuring are capacity and performance.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Volatility</span></span>\r\nNon-volatile memory retains the stored information even if not constantly supplied with electric power. It is suitable for long-term storage of information. Volatile memory requires constant power to maintain the stored information. The fastest memory technologies are volatile ones, although that is not a universal rule. Since the primary storage is required to be very fast, it predominantly uses volatile memory.\r\nDynamic random-access memory is a form of volatile memory that also requires the stored information to be periodically reread and rewritten, or refreshed, otherwise it would vanish. Static random-access memory is a form of volatile memory similar to DRAM with the exception that it never needs to be refreshed as long as power is applied; it loses its content when the power supply is lost.\r\nAn uninterruptible power supply (UPS) can be used to give a computer a brief window of time to move information from primary volatile storage into non-volatile storage before the batteries are exhausted. Some systems, for example EMC Symmetrix, have integrated batteries that maintain volatile storage for several minutes.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Mutability</span></span>\r\n<span style=\"font-weight: bold;\">Read/write storage or mutable storage</span>\r\n<div class=\"indent\">Allows information to be overwritten at any time. A computer without some amount of read/write storage for primary storage purposes would be useless for many tasks. Modern computers typically use read/write storage also for secondary storage.</div>\r\n<span style=\"font-weight: bold;\">Slow write, fast read storage</span>\r\n<div class=\"indent\">Read/write storage which allows information to be overwritten multiple times, but with the write operation being much slower than the read operation. Examples include CD-RW and SSD.</div>\r\n<span style=\"font-weight: bold;\">Write once storage</span>\r\n<div class=\"indent\">Write Once Read Many (WORM) allows the information to be written only once at some point after manufacture. Examples include semiconductor programmable read-only memory and CD-R.</div>\r\n<span style=\"font-weight: bold;\">Read only storage</span>\r\n<div class=\"indent\">Retains the information stored at the time of manufacture. Examples include mask ROM ICs and CD-ROM.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Accessibility</span></span>\r\n<span style=\"font-weight: bold;\">Random access</span>\r\n<div class=\"indent\">Any location in storage can be accessed at any moment in approximately the same amount of time. Such characteristic is well suited for primary and secondary storage. Most semiconductor memories and disk drives provide random access.</div>\r\n<span style=\"font-weight: bold;\">Sequential access</span>\r\n<div class=\"indent\">The accessing of pieces of information will be in a serial order, one after the other; therefore the time to access a particular piece of information depends upon which piece of information was last accessed. Such characteristic is typical of off-line storage.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Addressability</span></span>\r\n<span style=\"font-weight: bold;\">Location-addressable</span>\r\n<div class=\"indent\">Each individually accessible unit of information in storage is selected with its numerical memory address. In modern computers, location-addressable storage usually limits to primary storage, accessed internally by computer programs, since location-addressability is very efficient, but burdensome for humans.</div>\r\n<span style=\"font-weight: bold;\">File addressable</span>\r\n<div class=\"indent\">Information is divided into files of variable length, and a particular file is selected with human-readable directory and file names. The underlying device is still location-addressable, but the operating system of a computer provides the file system abstraction to make the operation more understandable. In modern computers, secondary, tertiary and off-line storage use file systems.</div>\r\n<span style=\"font-weight: bold;\">Content-addressable</span>\r\n<div class=\"indent\">Each individually accessible unit of information is selected based on the basis of (part of) the contents stored there. Content-addressable storage can be implemented using software (computer program) or hardware (computer device), with hardware being faster but more expensive option. Hardware content addressable memory is often used in a computer's CPU cache.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Capacity</span></span>\r\n<span style=\"font-weight: bold;\">Raw capacity</span>\r\n<div class=\"indent\">The total amount of stored information that a storage device or medium can hold. It is expressed as a quantity of bits or bytes (e.g. 10.4 megabytes).</div>\r\n<span style=\"font-weight: bold;\">Memory storage density</span>\r\n<div class=\"indent\">The compactness of stored information. It is the storage capacity of a medium divided with a unit of length, area or volume (e.g. 1.2 megabytes per square inch).</div>\r\n\r\n<span style=\"font-weight: bold;\"><span style=\"font-style: italic;\">Performance</span></span>\r\n<span style=\"font-weight: bold;\">Latency</span>\r\n<div class=\"indent\">The time it takes to access a particular location in storage. The relevant unit of measurement is typically nanosecond for primary storage, millisecond for secondary storage, and second for tertiary storage. It may make sense to separate read latency and write latency (especially for non-volatile memory[8]) and in case of sequential access storage, minimum, maximum and average latency.</div>\r\n<span style=\"font-weight: bold;\">Throughput</span>\r\n<div class=\"indent\">The rate at which information can be read from or written to the storage. In computer data storage, throughput is usually expressed in terms of megabytes per second (MB/s), though bit rate may also be used. As with latency, read rate and write rate may need to be differentiated. Also accessing media sequentially, as opposed to randomly, typically yields maximum throughput.</div>\r\n<span style=\"font-weight: bold;\">Granularity</span>\r\n<div class=\"indent\">The size of the largest &quot;chunk&quot; of data that can be efficiently accessed as a single unit, e.g. without introducing additional latency.</div>\r\n<span style=\"font-weight: bold;\">Reliability</span>\r\n<div class=\"indent\">The probability of spontaneous bit value change under various conditions, or overall failure rate.</div>\r\nUtilities such as hdparm and sar can be used to measure IO performance in Linux.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Energy use</span></span>\r\n<ul><li>Storage devices that reduce fan usage, automatically shut-down during inactivity, and low power hard drives can reduce energy consumption by 90 percent.</li><li>2.5-inch hard disk drives often consume less power than larger ones. Low capacity solid-state drives have no moving parts and consume less power than hard disks. Also, memory may use more power than hard disks. Large caches, which are used to avoid hitting the memory wall, may also consume a large amount of power.</li></ul>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Security</span></span>\r\nFull disk encryption, volume and virtual disk encryption, andor file/folder encryption is readily available for most storage devices.\r\nHardware memory encryption is available in Intel Architecture, supporting Total Memory Encryption (TME) and page granular memory encryption with multiple keys (MKTME) and in SPARC M7 generation since October 2015.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Storage_General_Purpose_Disk_Arrays.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":788,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/denovo.jpg","logo":true,"scheme":false,"title":"Cloud Datacenter","vendorVerified":0,"rating":"1.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":0,"alias":"cloud-datacenter","companyTitle":"De Novo","companyTypes":["supplier","vendor"],"companyId":237,"companyAlias":"de-novo","description":"Varied in backup policy and SLA terms, service classes allow for optimal choice for any business needs – EXPRESS (Express / Silver), ENTERPRISE (Silver / Gold / Platinum), TURBO (Turbo-Silver / Gold).\r\nWith De Novo Cloud Datacenter (Infrastructure as a Service, IaaS) you’re leveraging all the benefits of the cloud-based IT model:\r\nHigh performance.

A business typically relies heavily upon the applications, services and data contained within a data center, making it a focal point and critical asset for everyday operations.\r\nData centers are not a single thing, but rather, a conglomeration of elements. 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. 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).

These core characteristics are volatility, mutability, accessibility, and addressability. For any particular implementation of any storage technology, the characteristics worth measuring are capacity and performance.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Volatility</span></span>\r\nNon-volatile memory retains the stored information even if not constantly supplied with electric power. It is suitable for long-term storage of information. Volatile memory requires constant power to maintain the stored information. The fastest memory technologies are volatile ones, although that is not a universal rule. Since the primary storage is required to be very fast, it predominantly uses volatile memory.\r\nDynamic random-access memory is a form of volatile memory that also requires the stored information to be periodically reread and rewritten, or refreshed, otherwise it would vanish. Static random-access memory is a form of volatile memory similar to DRAM with the exception that it never needs to be refreshed as long as power is applied; it loses its content when the power supply is lost.\r\nAn uninterruptible power supply (UPS) can be used to give a computer a brief window of time to move information from primary volatile storage into non-volatile storage before the batteries are exhausted. Some systems, for example EMC Symmetrix, have integrated batteries that maintain volatile storage for several minutes.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Mutability</span></span>\r\n<span style=\"font-weight: bold;\">Read/write storage or mutable storage</span>\r\n<div class=\"indent\">Allows information to be overwritten at any time. A computer without some amount of read/write storage for primary storage purposes would be useless for many tasks. Modern computers typically use read/write storage also for secondary storage.</div>\r\n<span style=\"font-weight: bold;\">Slow write, fast read storage</span>\r\n<div class=\"indent\">Read/write storage which allows information to be overwritten multiple times, but with the write operation being much slower than the read operation. Examples include CD-RW and SSD.</div>\r\n<span style=\"font-weight: bold;\">Write once storage</span>\r\n<div class=\"indent\">Write Once Read Many (WORM) allows the information to be written only once at some point after manufacture. Examples include semiconductor programmable read-only memory and CD-R.</div>\r\n<span style=\"font-weight: bold;\">Read only storage</span>\r\n<div class=\"indent\">Retains the information stored at the time of manufacture. Examples include mask ROM ICs and CD-ROM.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Accessibility</span></span>\r\n<span style=\"font-weight: bold;\">Random access</span>\r\n<div class=\"indent\">Any location in storage can be accessed at any moment in approximately the same amount of time. Such characteristic is well suited for primary and secondary storage. Most semiconductor memories and disk drives provide random access.</div>\r\n<span style=\"font-weight: bold;\">Sequential access</span>\r\n<div class=\"indent\">The accessing of pieces of information will be in a serial order, one after the other; therefore the time to access a particular piece of information depends upon which piece of information was last accessed. Such characteristic is typical of off-line storage.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Addressability</span></span>\r\n<span style=\"font-weight: bold;\">Location-addressable</span>\r\n<div class=\"indent\">Each individually accessible unit of information in storage is selected with its numerical memory address. In modern computers, location-addressable storage usually limits to primary storage, accessed internally by computer programs, since location-addressability is very efficient, but burdensome for humans.</div>\r\n<span style=\"font-weight: bold;\">File addressable</span>\r\n<div class=\"indent\">Information is divided into files of variable length, and a particular file is selected with human-readable directory and file names. The underlying device is still location-addressable, but the operating system of a computer provides the file system abstraction to make the operation more understandable. In modern computers, secondary, tertiary and off-line storage use file systems.</div>\r\n<span style=\"font-weight: bold;\">Content-addressable</span>\r\n<div class=\"indent\">Each individually accessible unit of information is selected based on the basis of (part of) the contents stored there. Content-addressable storage can be implemented using software (computer program) or hardware (computer device), with hardware being faster but more expensive option. Hardware content addressable memory is often used in a computer's CPU cache.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Capacity</span></span>\r\n<span style=\"font-weight: bold;\">Raw capacity</span>\r\n<div class=\"indent\">The total amount of stored information that a storage device or medium can hold. It is expressed as a quantity of bits or bytes (e.g. 10.4 megabytes).</div>\r\n<span style=\"font-weight: bold;\">Memory storage density</span>\r\n<div class=\"indent\">The compactness of stored information. It is the storage capacity of a medium divided with a unit of length, area or volume (e.g. 1.2 megabytes per square inch).</div>\r\n\r\n<span style=\"font-weight: bold;\"><span style=\"font-style: italic;\">Performance</span></span>\r\n<span style=\"font-weight: bold;\">Latency</span>\r\n<div class=\"indent\">The time it takes to access a particular location in storage. The relevant unit of measurement is typically nanosecond for primary storage, millisecond for secondary storage, and second for tertiary storage. It may make sense to separate read latency and write latency (especially for non-volatile memory[8]) and in case of sequential access storage, minimum, maximum and average latency.</div>\r\n<span style=\"font-weight: bold;\">Throughput</span>\r\n<div class=\"indent\">The rate at which information can be read from or written to the storage. In computer data storage, throughput is usually expressed in terms of megabytes per second (MB/s), though bit rate may also be used. As with latency, read rate and write rate may need to be differentiated. Also accessing media sequentially, as opposed to randomly, typically yields maximum throughput.</div>\r\n<span style=\"font-weight: bold;\">Granularity</span>\r\n<div class=\"indent\">The size of the largest &quot;chunk&quot; of data that can be efficiently accessed as a single unit, e.g. without introducing additional latency.</div>\r\n<span style=\"font-weight: bold;\">Reliability</span>\r\n<div class=\"indent\">The probability of spontaneous bit value change under various conditions, or overall failure rate.</div>\r\nUtilities such as hdparm and sar can be used to measure IO performance in Linux.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Energy use</span></span>\r\n<ul><li>Storage devices that reduce fan usage, automatically shut-down during inactivity, and low power hard drives can reduce energy consumption by 90 percent.</li><li>2.5-inch hard disk drives often consume less power than larger ones.

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.

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":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.

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 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.

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.

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.

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":293,"title":"System Software","alias":"system-software","description":" System software is a type of computer program that is designed to run a computer’s hardware and application programs. If we think of the computer system as a layered model, the system software is the interface between the hardware and user applications. The operating system (OS) is the best-known example of system software. The OS manages all the other programs on a computer.\r\nOther examples of system software include:\r\n<ul><li>The BIOS (basic input/output system) gets the computer system started after you turn it on and manages the data flow between the operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.</li><li>The boot program loads the operating system into the computer's main memory or random access memory (RAM).</li><li>An assembler takes basic computer instructions and converts them into a pattern of bits that the computer's processor can use to perform its basic operations.</li><li>A device driver controls a particular type of device that is attached to your computers, such as a keyboard or a mouse. The driver program converts the more general input/output instructions of the operating system to messages that the device type can understand.</li></ul>\r\nAdditionally, system software can also include system utilities, such as the disk defragmenter and System Restore, and development tools, such as compilers and debuggers.\r\nSystem software and application programs are the two main types of computer software. Unlike system software, an application program (often just called an application or app) performs a particular function for the user. Examples include browsers, email clients, word processors, and spreadsheets.","materialsDescription":" \r\n<span style=\"font-weight: bold; \">What is system software?</span>\r\nSystem software is software designed to provide a platform for other software. Examples of system software include operating systems like macOS, GNU/Linux and Microsoft Windows, computational science software, game engines, industrial automation, and software as a service applications.\r\nIn contrast to system software, software that allows users to do user-oriented tasks such as create text documents, play games, listen to music, or browse the web are collectively referred to as application software.\r\nIn the early days of computing most application software was custom-written by computer users to fit their specific hardware and requirements. In contrast, system software was usually supplied by the manufacturer of the computer hardware and was intended to be used by most or all users of that system.\r\nThe line where the distinction should be drawn is not always clear. Many operating systems bundle[jargon] application software. Such software is not considered system software when it can be uninstalled usually without affecting the functioning of other software. Exceptions could be e.g. web browsers such as Internet Explorer where Microsoft argued in court that it was system software that could not be uninstalled. Later examples are Chrome OS and Firefox OS where the browser functions as the only user interface and the only way to run programs (and other web browsers can not be installed in their place), then they can well be argued to be (part of) the operating system and hence system software.\r\nAnother borderline example is cloud-based software. This software provides services to a software client (usually a web browser or a JavaScript application running in the web browser), not to the user directly, and is therefore systems software. It is also developed using system programming methodologies and systems programming languages. Yet from the perspective of functionality there is little difference between a word processing application and word processing web application.\r\n<span style=\"font-weight: bold; \">Operating systems or system control program</span>\r\nThe operating system (prominent examples being Microsoft Windows, macOS, Linux, and z/OS), allows the parts of a computer to work together by performing tasks like transferring data between memory and disks or rendering output onto a display device. It provides a platform (hardware abstraction layer) to run high-level system software and application software.\r\nA kernel is the core part of the operating system that defines an API for applications programs (including some system software) and an interface to device drivers.\r\nDevice drivers, including also computer BIOS and device firmware, provide basic functionality to operate and control the hardware connected to or built into the computer.\r\nA user interface &quot;allows users to interact with a computer.&quot; Either a command-line interface (CLI) or, since the 1980s a graphical user interface (GUI). Since this is the part of the operating system the user directly interacts with, it may be considered an application and therefore not system software.\r\n<span style=\"font-weight: bold;\">Utility software or system support programs</span>\r\nFor historical reasons, some organizations use the term systems programmer to describe a job function which is more accurately termed systems administrator. Software tools these employees use are then called system software. This so-called Utility software helps to analyze, configure, optimize and maintain the computer, such as virus protection. In some publications, the term system software also includes software development tools (like a compiler, linker or debugger).","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_System_and_Network_Management_Software.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":1044,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/microsoft.png","logo":true,"scheme":false,"title":"Microsoft System Center Virtual Machine Manager Analytics solution","vendorVerified":0,"rating":"2.00","implementationsCount":2,"suppliersCount":0,"supplierPartnersCount":272,"alias":"microsoft-system-center-virtual-machine-manager-analytics-solution","companyTitle":"Microsoft","companyTypes":["vendor"],"companyId":163,"companyAlias":"microsoft","description":"The Virtual Machine Manager Analytics solution comes with some built-in reports with preconfigured data visualizations so you can easily get started with frequently used queries, such as:\r\n\r\n<ul><li>Distribution of failed jobs across VMM instances to easily scope down the broken instances.</li><li>Distribution of failures over time to find sudden spikes, and to help with correlating the cause and failures.</li><li>Distribution of failed jobs and errors to help with identifying the most error-prone jobs and the cause.</li><li>Distribution of the job runtime across different runs to identify the sluggish and error-prone jobs.</li></ul>\r\nThese are just a few examples of the possibilities with Virtual Machine Manager Analytics.

While SAN products have been offering integrated hardware/software replication solutions for years, virtualization vendors have started integrating this feature into their newer products. VMware, for example, offers a storage replication feature in its newest version of vSphere. If you already have a SAN that supports replication you can choose how you want to replicate. Not a bad idea since VMware’s solution is version 1.0. One of the replication chief benefits is its ability to automate the process of data backup and redundancy.\r\nRestoring your data is as simple as the original storage replication process. You just go online and switch over to the replicated server. Depending on your provider, the complexity of your infrastructure and your comfort level with technology, it may also be possible to set an automatic failover to prevent any customer-facing outage at all. But recovery is as simple as getting online and synchronizing the replicated data to the original server, restoring it to the state of its last backup. You will still have some data loss, the transactions, and records from the intervening period. But if that backup was recent, within the last day or two, the effort required to reconstruct lost transactions and records will be relatively minor.\r\nIt's important to understand that storage replication only insures you against hardware failures, and does nothing about the risk of accidental deletion or of your virtualization provider failing to follow best practices. If you have replicated your data, you have a copy of it as it existed at the moment you replicated it.

Different from backups, data replicas update frequently rather than retain one unchanged copy for an extended period.\r\nData replication software ensures consistency for end-users accessing multiple data stores in the normal course of business. Other potential uses are zero-downtime data migration and multi-site replication for business continuity in case of site disaster.

This type of software is sometimes called “event success software” or an “events cloud.”\r\n<p class=\"align-left\"><span style=\"color: rgb(97, 97, 97); \">Events are becoming more prevalent than ever and event management software is what is allowing them to do so. <span style=\"font-weight: bold; \">Today’s event management platform:</span></span></p>\r\n<ul><li><span style=\"color: rgb(97, 97, 97); \">Fulfills a wide range of functions such as event registration, event marketing and reporting.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Drives event success for a variety of B2B and B2C events.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Helps event organizers save time, save money, increase security and reduce event headaches thanks to a structure that is seamlessly integrated from end-to-end.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Should be reliable easy-to-use, come with a dedicated customer success team and should measurably impact your event goals.</span></li><li><span style=\"color: rgb(97, 97, 97); \">And should be sold as a complete product, not a series of add-ons.</span></li></ul>\r\nThe most common event management applications are event schedule planning; customized event website creation; online event registration platforms; ticketing and delegate management including online payment; event budgeting; lead retrieval; event venue booking software; procurement, sourcing, and RFPs event marketing; event networking for attendee engagement; content management including abstract and/or paper management, reviewing, program development and publishing; exhibition management including floor planning, booking and billing; on-site operations including registration, badges, and networking; audience response solutions, live slide sharing and second-screen tools as live polls, Q+A, etc. \r\n\r\n","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: bold; \">Why Use Event Management Software?</span></h1>\r\n<p class=\"align-left\">What are the benefits of an event management software? These solutions can streamline or automate the back office processes in running an event. From pre-event, event and to post-event, these solutions provide efficiency, accuracy and cost savings. Here are the main benefits:</p>\r\n<ul><li><span style=\"font-weight: bold; \">Consolidate different teams</span></li></ul>\r\nEvents software systems provide a single platform that coordinates the tasks and activities, not just of the event team, but of your various teams, including sales &amp; marketing, logistics, accounting and travel management. It makes it easy to associate the different but connected items across your organization. A change in one item, for example, can trigger alerts on related items ensuring everyone has the latest information. A shift in venue, increase in attendance, change in menu, etc. are cases that require quick coordination among teams.\r\n<ul><li><span style=\"font-weight: bold; \">Lower overheads</span></li></ul>\r\nWith across and top-down visibility on your event operations, it is easy to control expenses and keep to budget caps leading to savings and higher returns. Likewise, event management services are good at automating certain event management processes, thereby, you cut down on time spent in completing tasks. This can translate to reduced staff time. Moreover, a small team can perform multiple tasks with the aid of a good event solution. Tools like coding-free event web builder, self-service online registration, autoresponders and data management perform some of the most time-consuming back office processes in organizing events, freeing you from soliciting additional contractors.\r\n<ul><li><span style=\"font-weight: bold; \">Smooth workflows in the entire event lifecycle</span></li></ul>\r\nSome event software programs solutions help you from planning to promotion to on-site operation and to post-event evaluation. They feature tools for event management, event marketing and post-analytics reporting and survey mechanism. Many of these tools ease out off your shoulder the traditional burden of building your database. Online registration, for example, allows participants enter their details instead of you. The database can be sorted differently, too, for targeted email marketing.\r\n<ul><li><span style=\"font-weight: bold; \">More focused event marketing</span></li></ul>\r\nCritical to the success of your event is a long-term promotion. Months (or even years) before the event, the solution, depending on its sophistication, can help you aggregate social media mentions, online communities, mailing lists, media and blog placements, etc. so you can start engaging potential participants. Some event management packages provide communication channels to get prospects’ feedback or questions or build a mailing list for staggered and targeted email marketing stages leading to the event date.\r\n<ul><li><span style=\"font-weight: bold; \">Efficient data management</span></li></ul>\r\nWith a single database event management software solutions can collate online registration details, sort them for various email marketing campaigns and run real-time and post-event analytics for insights. A centralized database also means various users are accessing the same latest data, eliminating misinformation. Different parties are quickly notified of changes in the database like number of participant, venue, programme, etc. Documents and reports are likewise updated and consistent throughout the organization.

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"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":386,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/vmware_vSphere.jpg","logo":true,"scheme":false,"title":"VMware vSphere","vendorVerified":0,"rating":"2.40","implementationsCount":6,"suppliersCount":0,"supplierPartnersCount":97,"alias":"vmware-vsphere","companyTitle":"VMware","companyTypes":["vendor"],"companyId":168,"companyAlias":"vmware","description":"<span style=\"font-weight: bold; \">VMware vSphere</span> is a cloud computing platform for virtualization.

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"},{"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":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.

A business typically relies heavily upon the applications, services and data contained within a data center, making it a focal point and critical asset for everyday operations.\r\nData centers are not a single thing, but rather, a conglomeration of elements. 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. 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.

A business typically relies heavily upon the applications, services and data contained within a data center, making it a focal point and critical asset for everyday operations.\r\nData centers are not a single thing, but rather, a conglomeration of elements. 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. 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.

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":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.

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,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/vmware_logo.png","logo":true,"scheme":false,"title":"VMWARE vRealize Network Insight","vendorVerified":0,"rating":"2.40","implementationsCount":1,"suppliersCount":0,"supplierPartnersCount":97,"alias":"vmware-vrealize-network-insight","companyTitle":"VMware","companyTypes":["vendor"],"companyId":168,"companyAlias":"vmware","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. 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. A business typically relies heavily upon the applications, services and data contained within a data center, making it a focal point and critical asset for everyday operations.\r\nData centers are not a single thing, but rather, a conglomeration of elements. 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. 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).

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.
