Virtualisation is a form of machine abstraction that creates a simulated, or virtualised, instance of a machine using physical hardware. It provides a very high degree of isolation between multiple machines on the same host.
Virtualisation is a form of machine abstraction that creates a simulated, or virtualised, instance of a machine using physical hardware. It provides a very high degree of isolation between multiple machines on the same host.
By creating multiple machines on a single host, the density of applications or processes executing on a single host is increased, which increases the utilisation of the physical hardware.
Origins of Virtualisation can be traced back to the 1960s where mainframe computers were logically divided between different applications. VMWare popularised Virtualisation in 2009 with their VSphere and VMWare Workstation products.
