It was called Remote Desktop before, but some security problems, and the fact you can connect to a program running on a server (rather than the whole OS interface) .. Made them rename it, most of the tech is still the same though and most guides still apply to it.
Come to think of it, I seem to remember that the connect to an app, rather than desktop functionality was available in Windows Server 2012, so renaming it now is a delayed response at best.
