VIRTUALIZATION
Definition

Cloud Computing Is A Set Of Principles And Approaches To Deliver Compute, Network, And Storage Infrastructure Resources, Services, Platforms, And Applications To Users On-Demand Across Any Network

Virtualization Is A Software Which Creates “Separated” Multiple Images Of The Hardware And Software On The Same Machine. This Makes Possible To Install Multiple OS, Multiple Software And Multiple Applications On The Same Physical Machine
