In reference to the above article I would like some clarification
1) Remote Desktop Gateway - I am assuming this is not an essential requirement for what used to be the old Terminal Services - e.g. you log into a Terminal Server and get a desktop and away you go. My reading on Remote Desktop Gateway is that it is an 'add-on' that you can put into place for enhanced control of remote access - one secure, controllable channel to come through - but if you choose not to put it into place you still can have remote desktop services a la old TS. Am I on track?
2) VDI - My reading of this is that I could have a pile/pool of workstation VHD base images e.g. Vista, Windows 7 and that different users could access these shared images and would get their own customized configuration. Example: I have a single base Windows 7 VHD. When two different userss log on to their virtualized Windows 7 they are sharing a single VHD image but with different profiles/desktops as per their preferences so in effect they have a 'Terminal Services' type of experience - one TS Server but many desktops. Is that the gist of it?
Any assistance is appreciated in advance in particular any links to resources that someone might be aware of in regard to the new features of Remote Desktop.
