Detailed explanation-2: -Infrastructure as a Service (IaaS) is a cloud computing service where enterprises rent or lease servers for compute and storage in the cloud.

Detailed explanation-5: -Indeed, IaaS/PaaS/SaaS are in fact, just that. They are all virtualization solutions, just at different levels of the computing stack. IaaS, for example, is aimed at virtualizing the hardware from the operating system. SaaS, however, is virtualizing the application from the operating system.
