Desktop virtualisation leverages the benefits of centralised computing while allowing users to retain their own virtual workspace instance. Each desktop resource runs as a virtual machine on a server which, unbeknown to the user, is shared with many others, reducing costs substantially.
Within organisations, different types of users require different types of desktops. Some require simplicity and standardisation, while others need performance and personalisation. Centralising the management and delivery of virtual desktops that are tailored to the needs of the users can be delivered seamlessly to their desktop PC, laptop or mobile devices regardless of what applications or operating system is required.

These virtual machines are spawned from a single, or collection of base images.
There are various types of desktops that can be deployed to users, the three main scenarios are:
