  • In computing, a virtualization is the facility that allows multiple operating systems (VMs) to run simultaneously on a computer in a safe and efficient manner.



  • Virtualization purposes:
    - Application development and testing on a separate system,
    - Server consolidation on one platform,
    - Virtual appliances (download a VM applience for specific application or service)
    - Prototyping and setting VMs to run on a remote server or/and cloud.
    - Multiple Operating systems on a desktop.
