Understanding Remote Desktop Services (RDS)

In Windows Server 2008 R2 (WS2008R2), Terminal Services (TS) has been expanded and renamed to Remote Desktop Services (RDS). RDS is the backbone of Microsoft's VDI solutions. And in Windows Server 2012, RDS is further enhanced and with a scenario-based configuration wizard. Still the concept and architecture remain very much the same since WS2008R2. The new and enhanced architecture takes advantage of virtualization and makes remote access a much flexible solution with new deployment scenarios. To realize the capabilities of RDS, it is essential to understand the functions of key... (more)
