Microsoft Terminal Services has become Remote Desktop Services (RDS) in Windows Server 2008 R2. As such, the Client Access License (CAL) changed its name as well.
Not only did the CAL name change but, it costs more. Such is the way of things. However, for that increase not only are you able to access new functionality Microsoft have additionaly included a Microsoft Application Virtualization for Terminal Services (App-V for TS) license.
This does not only have a bearing on Presentation Virtualization deployments, but could well impact the growth of other vendor’s Application Virtualization solutions.
