RemoteFX, a technology acquired with Callista acquisition in 2008, was first integrated into Windows Server 2008 R2 SP1 as a removing solution for high-end graphic applications.
“If you are familiar with Windows Server 2008 R2 SP1, we had introduced RemoteFX, but it was solving a very particular problem,” Daga said during the TechEd talk. “It was referencing primarily to the virtual graphics processor available on Windows Server for virtualizing inside your guest VM. There were a couple of other things like the codec and USB redirection that were tied in with that RemoteFX GPU, but now, in [Windows Server] 2012, RemoteFX is our umbrella brand that covers all our rich remoting experiences over both LAN or WAN conditions.”
