Virtual desktop infrastructure (VDI) separates the operating system and applications from the client device, providing a model of desktop computing that is much more flexible and efficient than traditional solutions. Virtual desktop instances can be built, deployed, patched, and managed from one central location rather than having to do this in each individual classroom, lab, or office. VDI also increases mobility and provides a more secure computing environment in several ways. Successful implementations require a robust infrastructure to deliver a typical desktop image. With VDI, the cost structure for providing desktop computing changes, saving money for most institutions, and many colleges and universities are expected to begin using VDI over the next few years.
