A technique that uses software called Hypervisor (virtual machine manager or VMM) to create abstraction of hardware.
- Hardware is divided into multiple virtual computers, called Virtual Machines (VMs)
- Each VM runs its own OS, called Guest OS, and behaves like an independent computer! Application processes can run on the guest OS as if it is an independent computer
- Each VM is using only a portion of the actual hardware
More efficient utilisation of hardware
- Cost effective hardware deployment and sharing
- Low latency and agile execution environments
- Failure mitigation (VM independence and migrations) Enables cloud computing
Software layer required for managing the virtualization
