- VIRTUALIZATION -
In computing, virtualization refers to the act of creating a virtual (rather than actual) version of something, including virtual computer hardware platforms, operating systems, storage devices, and computer network resources.
Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute. Virtualization lets you run multiple virtual servers or desktops on a single physical machine (host), sharing the resources of that single computer across multiple environments.
So why virtualization? Why virtualization has emerged as the most dramatic market inflection of the decade and has resulted in millions of dollars of savings.
Simply put, it’s the process of creating a virtual, rather than physical, version of something. Virtualization can apply to computers, operating systems, storage devices, applications, or networks. However, server virtualization is at the heart of it.
IT organizations are challenged by the limitations of today’s x86 servers, which are designed to run just one operating system and application at a time. As a result, even small data centers have to deploy many servers, each operating at just 5 to 15 percent of capacity—highly inefficient by any standard.
Virtualization uses software to simulate the existence of hardware and create a virtual computer system. Doing this allows businesses to run more than one virtual system – and multiple operating systems and applications -- on a single server. This can provide economies of scale and greater efficiency.
