For example: 1. Eliminates server acquisition via virtual machines or VMs that offer transparent shared hardware. 2. Tightens the [disaster recovery] window by encapsulating large systems into single files the can be easily replicated and stored and then restored to minimize lost work time. 3. Secures end user PCs without reducing end user PCs by placing security software inside the Virtualization Layer.
Running multiple operating systems on shared hardware resource is know as partitioning the most common form of Virtualization. This approach is quickly being replaced by hypervisor architecture some time commonly referred to as the "bare metal approach" because the layer of Virtualization software is applied directly to the enterprise architecture.
Facts: The most common platform for Virtualization is the x86 Architecture The most common Virtualization layer is VMWare. The most recent release is VMware Infrastructure 3: v3.5
