SQL Azure
The Windows Azure platform offers the optional SQL Azure database as a supplement to the rudimentary data storage provided by the Storage AppFabric. Unlike the storage appFabric, SQL Azure is a cloud-based relational database that is an extension of Microsoft SQL Server. This multi-tenant, highly scalable database runs in the Azure cloud. This cloud-based database supports the same T-SQL version of SQL as existing SQL Server databases. In addition, SQL Azure offers standard relational database features such as triggers, views, stored procedures, and indexes.
