Desktop virtualization is the concept of separating a personal computer desktop environment from the physical machine through a client-server computing model. The resulting "virtualized" desktop is stored on a remote central server, instead of on the local storage of remote client; this way, when users work from their remote desktop client, all of the programs, applications, processes, and data used are kept and run centrally, allowing users to access their desktops on any capable device, such as a traditional personal computer, notebook computer, smartphone, or thin client.

Simpler provisioning of new desktops Reduced downtime in the event of server

or client hardware failures Lower cost of new application

deployment Desktop image management capabilities Longer refresh cycle for client desktop

infrastructure Secure remote access to the enterprise

desktop environment

Limitations of desktop virtualization include: potential security risks if the network is

not properly managed some loss of user autonomy and privacy challenges in setting up and maintaining

drivers for printers and other peripherals difficulty in running certain complex

applications such as multimedia (GIS, Video).

According to a report by Gartner, hosted services accounted for more than 500,000 desktop units as of March 2009, but will grow to 49 million desktop units by 2013, and may make up as much as 40% of the worldwide professional personal computer market by revenue
