    Virtualization is the process of running a virtual instance of a computer system in an abstract layer of the physical hardware.     It ensures efficient utilization of physical computer hardware and is the foundation of cloud computing.     Virtualization uses a software to create an abstraction layer over computer hardware that allows the hardware  elements of a single computer  such as processor, memory , storage and more to be divided into multiple virtual computers , commonly called virtual machines(VMs)     Each VM  runs its own operating system and behaves like an independent computer, even though it is running on just a portion of the actual underlying hardware.     This is the technology that drives the cloud computing economics. This enables cloud providers to serve users with their existing physical computer hardware; it enables cloud users to purchase only the computer in resources they need when ...
