Virtual desktop integration is the practical use of a hosted operating system instance via browser access. VDI apps and operating system sessions execute on a remote host, often in a data center VDI farm. VDI has benefits but also potential problems as the hosts for VDI sessions migrate to the cloud.
As VDI sessions execute in a farm, sessions can be tightly controlled. Users tend to be highly mobile, and the machines they use can be difficult to keep updated and typically vary in configuration. VDI sessions are often highly homogenized–that is, similar in appearance, patch level, and so on (even generically so). Applications can also be virtualized, in a form called by varying names, but this article covers security with full sessions.
