  • An iterative approach to Desktop VirtualizationBy Mike Cave, Acting Chief Information OfficerCA Department of Toxic Substances Control

  • 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 desktopsReduced downtime in the event of server or client hardware failuresLower cost of new application deploymentDesktop image management capabilitiesLonger refresh cycle for client desktop infrastructureSecure remote access to the enterprise desktop environment

  • Limitations of desktop virtualization include:potential security risks if the network is not properly managedsome loss of user autonomy and privacychallenges in setting up and maintaining drivers for printers and other peripheralsdifficulty 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
