Desktop virtualization, often called client virtualization, is a virtualization technology used to separate a computer desktop environment from the physical computer. Desktop virtualization is considered a type of client-server computing model because the "virtualized" desktop is stored on a centralized, or remote, server and not the physical machine being virtualized.
Desktop virtualization "virtualizes desktop computers" and these virtual desktop environments are "served" to users on the network. You interact with a virtual desktop in the same way you would use a physical desktop. Another benefit of desktop virtualization is that is lets you remotely log in to access your desktop from any location.
VDI (Virtual Desktop Infrastructure -- or Interface) is a popular method of desktop virtualization. This type of desktop virtualization uses the server computing model, as the desktop virtualization in this scenario is enabled through hardware and software. VDI hosts the desktop environment in a virtual machine (VM) that runs on a centralized or remote server.
