Presentation virtualization is a method through which an application runs on one computer, but the graphical output of that application displays on another. Presentation virtualization includes technologies such as Remote Desktop Services (RDS), which had the name “Terminal Services” in Windows Server 2008 and Windows Server 2003. Microsoft Application Virtualization (App-V) allows administrators to deliver applications to computers without installing them directly. The application runs locally, but it is not installed locally. When App-V is configured properly, only those parts of the application that are required for successful execution are transmitted across the network. In this chapter, you will learn about presentation virtualization and App-V, including how to deploy applications so that clients will open virtualized applications automatically when a user double-clicks the appropriate document type.
