Virtualisation is the process of creating a virtual version of something, rather than an actual, physical version. Examples of virtualisation systems are virtual computer hardware platforms, storage devices, and computer network resources. Things that can be virtualised include memory, desktop infrastructure, storage and networks.

Fewer server and storage resources mean that virtualisation is more environmentally friendly, and it can also help with disaster recovery.
