Application virtualization is an umbrella term that describes software technologies that improve portability, manageability and compatibility of applications by encapsulating them from the underlying operating system on which they are executed. A fully virtualized application is not installed in the traditional sense[1], although it is still executed as if it is. The application is fooled at runtime into believing that it is directly interfacing with the original operating system and all the resources managed by it, when in reality it is not. Application virtualization differs from operating system virtualization in that in the latter case, the whole operating system is virtualized rather than only specific applications.
What's App-V?
Application virtualization is at the heart of Microsoft Application Virtualization (App-V). It decouples applications from the operating system and enables them to run as network services. Application virtualization can be layered on top of other virtualization technologies—network, storage, machine—to create a fully virtual IT environment where computing resources can be dynamically allocated in real-time based on real-time needs. App-V's patented application virtualization, dynamic streaming delivery, and centralized management technologies make everything from deployments and upgrades to migrations and business continuity initiatives easier and faster with better agility.
Virtualized application environments enable each application to bring its own set of configurations and run without any installation within a virtual run-time abstraction layer on the client, so dependencies or effects on the configuration of the operating system are minimized. However, since applications execute locally, they run with full performance, functionality, and access to local services - including cut and paste, OLE, printing, network drives, and attached devices.
