Desktop Virtualization

Hypervisor

Physical Server

▲ Ability to use your desktop environment from any PC with network or Internet access.

▲ Access to typical desktop features, such as multiple monitors, USB devices, and so on.

▲ Disaster recovery at the desktop is simplified, as a new device can be quickly installed to use the virtualized image on the server. Backups can be managed at the server level.

Virtualization of the desktop also creates the opportunity to have desktops provided through the Internet, much as many vendors are doing with applications using the "software as a service" (SaaS) model. For desktops, one term being used is "desktop as a service" (DaaS), while others use the term Virtual Desktop Infrastructure as a Service (VDI).

Some issues to be aware of when considering desktop virtualization:

▲ Your "per seat" cost may be initially higher because of the cost of the servers, virtualization software, and Windows licenses.

▲ The OEM version of Windows that comes with most new PCs cannot be used in a virtual environment; new licenses must be purchased.

▲ User resistance to giving up their full client PCs.
