Introduction

Virtualizations come in many different forms, shapes and usages. The objective of this report is to shine a light on virtualization as a whole as well as explain the different types of virtualization. Virtualization touches almost all the aspect of computing techniques. Virtualization came into practice use when virtual machines were used for various computing environment. There are significant differences and quite a few similarities about the different virtualizations we are going to get into details. ‘Hardware Virtualization’, a most prominent virtualization is a completely different beast compared to the ‘Operating System-Level Virtualization’, although both utilize the basic concept of a software technology.

“Virtualization is software technology which uses a physical resource such as a server and divides it up into virtual resources called virtual machines (VM's).  Virtualization allows users to consolidate physical resources, simplify deployment and administration, and reduce power and cooling requirements (Wikipedia)”. Virtualization has been very significant in the server world for a while now and at the same time it is taking over the date storage world with a momentous force.

Reasons for Virtualization

Before we get into the details about reasons for virtualization, we can say with an assurance that virtualization has completely changed the computing world forever. The computing world that started with...
