In ten years ago, we started to use Visual Studio Team Foundation Server. That sounds only a source control system. Last night, I went .net user group meeting for the new version of Visual Studio Team Service. The presentation is great. The new version have on-premise and on the cloud. Moreover, that is more than a source control system. It is similar with JIRA, and it can handle the change request and user story, you can use it to do scrum meeting. In addition, it is not for Visual Studio, it got the plug-in for eclipse and Android Studio. Also, it got build agents for Android and Linux too, even you use the cloud version, you can install a build agent on your computer. The on-cloud service can trigger the agent. Lastly, it just supports TFS, it supports ZGit, and can link up any external git system. That is great!
