Microsoft Application Virtualization SAL - Licence & software assurance - SPLA - Win - All Languages

Microsoft Application Virtualization (App-V) transforms applications into centrally managed virtual services that are never installed and don't conflict with other applications. In a physical environment, every application depends on its OS for a range of services, including memory allocation, device drivers, and much more. Incompatibility between an application and its OS can be addressed by either server virtualization or presentation virtualization - but for incompatibility between two applications installed on the same instance of an OS, you need Application Virtualization.
