The cloud service is backed by Microsoft’s cloud platform, Microsoft Azure.
It uses the same code as the on-premises version of TFS, with minor modifications, and implements the most recent features. A user signs in using a Microsoft account to set up an environment, creating projects and adding team members.
New features developed in short development cycles are added to the cloud version first.
These features migrate to the on-premises version as updates, at approximately three-month intervals.
If using Microsoft SQL Server 2012, Always On SQL Server Failover Clusters and Availability Groups are supported which allows for geographic replication of data. A project collection is a database that contains a group of Team Projects.
