SQL Server Data Services (SSDS), previously codenamed “Sitka”, has been announced at MIX08.  SSDS is a web-facing, storage and data processing service exposed over HTTP (via REST or SOAP).  Built on top of the SQL platform, SSDS is a highly scalable, pay-as-you-grow cloud-based data storage service.

A public beta will begin soon. Those interested in participating can sign up on the Data Services site.
