Where to get started with TFS and VSTS...
On a regular basis, I get the question, where do I even begin looking at Visual Studio Team System? Well, the Team Suite, and it's 4 included roles is a good start. But don't neglect TFS. The Team Foundation Server component when used in conjunction with the Suite or any of the role based editions adds so muich bang for the buck that it seems crazy to use one and not the other. Here are some good starting points if you want to get ramped up FAST!
