What is the difference between Microsoft Team Foundation Server and Microsoft Team Services?
Are Team Services also made for continuous integration and can it be used together with a self hosted git service?
Hope this is not off topic, thank a lot if some one could clearify this!
They are basically the same product, except one is cloud-hosted by Microsoft and the other is an on-premise installation.
VSTS gets features first, because it's on a 3-week release cycle. TFS is on the same release/update timeframe as Visual Studio for the most part.
The continuous integration piece allows you to use TFVC, TFS/VSTS-hosted Git, GitHub, Subversion (VSTS only at the moment), or any external Git provider.
