Virtualization: Hypervisor
A hypervisor is software between the physical hardware and the virtual machines.
Virtualization: Cloud
Virtualization of IT resources makes cloud computing, as we know it, possible; it includes server virtualization, storage virtualization, and network virtualization.
Virtualization: Network
Virtual machines can be set up with virtual Network Interface Cards (NICs), which connect to virtual switches, creating a virtual network.
Virtualization
Virtualization is the abstraction of computing resources from the physical hardware, making it possible to run several operating systems on one computer.
