Explanation:
MS App-V thus allows centralized installation and management of deployed applications. It supports policy based access control; administrators can define and restrict access to the applications by certain users by defining policies governing the usage. App-V can require that applications not be run 'cached' from workstations, or require that 'cached' App-V applications routinely update license information from the App- V server, enforcing license compliance. These policies are centrally applied on the application repository.
App-V also allows copy of the applications across multiple application servers for better scalability and fault tolerance, and also features a tracking interface to track the usage of the virtualized application.
