If you haven't heard, Microsoft changed the name of SQL Server in the cloud again. I guess they don't want people thinking that they are paying for a SQL service but paying for a SQL Azure. Guys, come on. I know it's not marketed very well but changing the name again. SSDS, SDS, now what is it? MSA MSAD.
The reason why people haven't adopted it is because it's still CTP. Once you get the new version out to public CTP it would have gone off like a rocket. Sorry for the rant but I liked Microsoft SQL Data Services much better.
By the way, in case you are new to Azure, Azure is a color. It's kind of like a cyan-blue. Azure is also what Microsoft seems to be calling everything they put in the cloud nowadays.
