Virtualization is an abstraction layer that's breaks the hard connection between the physical hardware and the operating system. A virtual infrastructure is an enterprise wide solution that provides fluid, powerful computing that maximizes resource utilization and cost savings.
Virtual machines are the key element to a virtual infrastructure. Virtualization allows you to run multiple virtual machines with hetrogeneous operating systems an applications to run in isolation, side-by-side on the same physical machine. Using virtualization, you can dynamically move resources where they are needed, and move processin
where it makes most sense. This is possible because VMware detaches the operating system and its applications from the hardware they run on.
