Guide: Data Center Virtualization for CompTIA Network+ Exam

What is Data Center Virtualization?
Data Center Virtualization is a process which involves the creation of a virtual version of a physical data center. It includes the abstraction of the various components like servers, storage devices, networks, etc. and allows multiple virtual environments to exist on a single physical environment.

Importance of Data Center Virtualization
Data Center Virtualization is important because it improves efficiency, reduces costs, allows quick deployment of resources and increases scalability. It is vital for cloud computing as it creates the foundation for the cloud.

How it Works
Virtualization operates by using a software, known as hypervisor, to divide one physical server into multiple isolated virtual environments. These environments are known as virtual machines that can run their own operating systems and applications just like a physical server.
