Virtualization has quickly become one of the most pressing issues for IT investment. The rapid adoption of virtualization can be attributed to both its short and long-term advantages which will allow organizations to reduce costs while making their infrastructures more flexible over time. Virtualization allows organizations to easily encapsulate existing applications into silos that can be moved between physical servers. All of the leading independent research firms agree that server and other forms of infrastructure virtualization have become a significant component of any successful organizations' competitive IT strategy. Virtual machines can be used to consolidate the workloads of several under-utilized servers to fewer machines, even a single machine. The real benefits of such a process are overall savings on hardware, environmental costs, management, and administration of the server infrastructure. Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute. Top 5 Reasons to Adopt Virtualization 1. Server Consolidation and Infrastructure Optimization: Virtualization makes it possible to achieve significantly higher resource utilization by pooling common infrastructure resources and breaking the legacy “one application to one server” model. 2. Physical Infrastructure Cost Reduction: With virtualization, you can reduce the number of servers and related IT hardware in the data center. This leads to reductions in real estate, power and cooling requirements, resulting in significantly lower IT costs. 3. Improved Operational Flexibility & Responsiveness: Virtualization offers a new way of managing IT infrastructure and can help IT administrators spend less time on repetitive tasks such as provisioning, configuration, monitoring and maintenance. 4. Increased Application Availability & Improved Business Continuity: Eliminate planned downtime and recover quickly from unplanned outages with the ability to securely backup and migrate entire virtual environments with no interruption in service. 5. Improved Desktop Manageability & Security: Deploy, manage and monitor secure desktop environments that end users can access locally or remotely, with or without a network connection, on almost any standard desktop, laptop or tablet PC. Server Virtualization Server virtualization is the masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users. The server administrator uses a software application to divide one physical server into multiple isolated virtual environments. The virtual environments are sometimes called virtual private servers, but they are also known as partitions, guests, instances, containers or emulations. Server virtualization can be viewed as part of an overall virtualization trend in enterprise IT that includes storage virtualization, network virtualization, and workload management Application Virtualization Application virtualization is an umbrella term that describes software technologies that improve portability, manageability and compatibility of applications by encapsulating them from the underlying operating system on which they are executed. Application virtualization separates the application configuration layer from the OS. It enables applications to run on clients – including desktops, servers and laptops – without being installed, and to be administered from a central location. This has huge implications for everything from patch and upgrade management to deploying and terminating applications. Desktop Virtualization Desktop virtualization (or Virtual Desktop Infrastructure) is a server-centric computing model that borrows from the traditional thin-client model but is designed to give system administrators and end-users the best of both worlds: the ability to host and centrally manage desktop virtual machines in the data center while giving end users a full PC desktop experience. Many commercial solutions also add the ability to switch some incoming client sessions (using connection broker software) towards traditional shared desktop systems such as Microsoft's Terminal Services or Citrix's application servers, blade servers or even to individual unused physical desktop computers. Employing the same approach as server virtualization, desktop virtualization lets you create separate virtual machines on your Windows desktop, each of which virtualizes the hardware of a complete physical computer. You can use Virtual Machines to run operating systems such as MS-DOS, Windows, and OS/2. You can also run multiple operating systems at once on a single physical desktop and switch between them as easily as switching applications - instantly, with a mouse click. The SparX approach :
