Explanation: Virtualization in Cloud Computing
Virtualization is the "creation of a virtual (rather than actual) version of something, such as a server, a desktop, a storage device, an operating system or network resources".
In other words, Virtualization is a technique, which allows to share a single physical instance of a resource or an application among multiple customers and organizations. It does
by assigning a logical name to a physical storage and providing a pointer to that physical resource when demanded.
What is the concept behind the Virtualization?
Creation of a virtual machine over existing operating system and hardware is known as Hardware Virtualization. A Virtual machine provides an environment that is logically separated
from the underlying hardware.
The machine on which the virtual machine is going to create is known as Host Machine and that virtual machine is referred as a Guest Machine
In a nutshell, virtualization is software that separates physical infrastructures to create various dedicated resources. It is the fundamental technology that powers cloud computing.
