Saving Money and Increasing Security of Desktops: Forget "VDI"
At its most broad (and literal) definition, the "virtualization" of a desktop happens whenever that desktop's logical management has been separated from the physical device. In today's world, many people think "VDI" when they think of "desktop virtualization." While it's true that VDI is one type of desktop virtualization, it's not the only type of desktop virtualization. (For those who aren't clear on the terms, "VDI" literally means "Virtual Desktop Infrastructure." But in common use, "VDI" means the "flavor of desktop virtualization where users' desktop computers are replaced with thin client devices, and then they use the thin clients to connect to Windows desktops running as VMs on a server in a datacenter").
