Cloud and Virtualization

Cloud

Cloud computing is computing model, not a technology. In this model of computing, all the servers, networks, applications and other elements related to data centers are made available to IT and end users via the Internet, in a way that allows IT to buy only the type and amount of computing services that they need.

Virtualization

virtualization is software that separates physical infrastructures to create various dedicated resources. It is the fundamental technology that powers cloud computing.
