What is Virtualization?
Virtualization refers to a set of techniques and tools to create a virtual (i.e., software-based) solution for processes that would typically require a physical platform. It is a very broad discipline that spreads into many different computing branches, including servers, personal workstations, and everything in between. Virtualization allows the same host/computer/server to run multiple guest operating systems using virtualization software known as a hypervisor and easily move virtual machines (VMs) between hosts.
