Desktop virtualization separates a desktop operating system and its applications from the physical device you access them on. The desktop itself runs centrally, on servers, in a datacenter, or in the cloud, and gets presented to you over a remoting protocol. The device becomes a viewer. The desktop becomes a service.
The desktop OS runs centrally, decoupled from whatever physical device is used to view it.
Three families cover most of the market. VDI gives each user a full desktop VM on central infrastructure. Session-based virtualization (RDS) hosts many users as sessions on shared Windows Server instances instead, trading isolation for density. DaaS is either of those, just run by a provider on subscription. There is a fourth, local desktop virtualization, a VM running on the user's own machine, but that solves developer and lab problems, not enterprise delivery.
The reasons keep repeating. Data centralization, so files never live on a laptop that gets lost or stolen. Device independence, so any endpoint, BYOD included, becomes a viable workstation. Operational leverage, patching one image instead of a thousand PCs. Workforce flexibility, onboarding and remote work without shipping a single box of hardware. Security cuts both ways here: centralizing desktops also centralizes everything that now has to be protected, which is exactly why the access layer ends up deciding whether any of this was actually a good idea.
Session-based RDS wins on density and cost when users are just running standard business apps. VDI wins when isolation, OS-level compatibility, or per-user customization actually matter. DaaS wins when you want no platform operations at all. Most real environments end up blending them anyway. The detailed decision lives in the VDI vs RDS comparison →
VDI is one form of it; the umbrella also covers RDS sessions and DaaS.
No. Plenty of it runs in on-premises datacenters. Cloud is just a location choice, not a requirement.
