There are two types of virtual desktop infrastructure (VDI) deployment methods: persistent VDI and nonpersistent VDI:

Persistent VDI deployment

Persistent VDI deployments are remote desktops that are saved for individual end users. Multiple users have persistent desktops that they can customize and reuse repeatedly.

Nonpersistent VDI deployment

Nonpersistent VDI deployments are single-use desktop instances. The centralized server creates a new generic desktop for every user and then destroys the desktop after use. Nonpersistent desktops are cost effective when organizations have a large workforce using business applications for repetitive administrative tasks. For example, call center employees require a standard set of applications for their work. Any data they create is stored remotely in the business application. You can set up a new nonpersistent VDI for them in every session, and it will not cause them to lose any work.
