Microsoft Application Virtualization (App-V) 4.5
App-V 4.5 is the first Microsoft-branded release of the product formerly known as SoftGrid. It includes new capabilities designed to help IT support large-scale virtualization implementations across many sites and provides multiple delivery options, including over-the-Internet application availability to meet your business needs.
App-V has several advantages. Because App-V applications are isolated from each other, different versions of the same application can run concurrently. This approach enables any application to be delivered without making any changes to its code. The App-V client presents the user with a list of applications, to which the user has access. The user can then launch a virtualized instance of the application. Depending on the configuration, the systems administrator can be either notified of the action via email or it can require an explicit confirmation from the administrator for the application to start streaming and initialize or it can just simply check the Active Directory for the user’s rights and stream the application to the user if it is authorized to run the application.
Microsoft Application Virtualization for Terminal Services supports Windows Server 2008 Terminal Services and its available as part of the Microsoft Desktop Optimization Pack and Microsoft Application Virtualization for Terminal Services.
