Architecting the Virtual Application Infrastructure at Microsoft
Microsoft is evaluating Microsoft Application Virtualization 4.5 (App-V) as a method to lower application management life cycle costs. App-V 4.5, in conjunction with Microsoft System Center Configuration Manager 2007 R2, provides an infrastructure for deploying virtualized rich client applications within an enterprise environment. When planned carefully, the same tools can be used to deploy a virtualized application that would normally deploy a desktop application.
