Desktop virtualization is the concept of separating the logical desktop from the physical machine.
One form of desktop virtualization, virtual desktop infrastructure (VDI), can be thought of as a more advanced form of hardware virtualization. Rather than interacting with a host computer directly via a keyboard, mouse, and monitor, the user interacts with the host computer using another desktop computer or a mobile device by means of a network connection, such as a LAN, Wireless LAN or even the Internet. In addition, the host computer in this scenario becomes a server computer capable of hosting multiple virtual machines at the same time for multiple users.
Deploying desktops as a managed service lets you respond more quickly to changing needs and opportunities. You can reduce costs and speed service by quickly and easily delivering virtualized desktops and applications to branch offices, outsourced and offshore employees, and mobile workers on iPad and Android tablets.
