What is Virtualization?

Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way people compute. Virtualization is a broad term that refers to the abstraction of computer resources. A single physical resource (such as a server, an operating system, an application, or storage device) appear to function as multiple logical resources or multiple physical resources (such as storage devices or servers) appear as a single logical resource.

Today’s powerful x86 computer hardware was originally designed to run only a single operating system and a single application, but virtualization breaks that bond, making it possible to run multiple operating systems and multiple applications on the same computer at the same time, increasing the utilization and flexibility of hardware.

The introduction of virtualization technology presents a number of opportunities for driving capital and operational efficiency above and beyond the simple benefits of safe partitioning.

Virtualization defined
Virtualization is loosely defined as a framework or methodology of dividing the resources of a computer into multiple execution environments, by applying one or more concepts or technologies such as hardware and software partitioning, time-sharing, partial or complete machine simulation, emulation, quality of service, and many others.

What is Virtual Infrastructure ?
Virtual infrastructure is a dynamic mapping of physical resources to business needs. While a virtual machine represents the physical resources of a single computer, a virtual infrastructure represents the physical resources of the entire IT environment, aggregating x86 computers and their attached network and storage into a unified pool of IT resources.

Why Virtualization ?
• Consolidate the workloads of several under-utilized servers
• Provide secure, isolated sandboxes for running un-trusted
    applications
• Physical infrastructure cost reduction
• Increased application availability & improved business continuity
• Improved desktop manageability & security
• Used to simulate networks of independent computers..
• Used to run multiple operating systems simultaneously
• Enable existing operating systems to run on shared memory     multiprocessors
• Used to retrofit new features in existing operating systems without "too much" work
