According to Charles Ying, SimpleDB runs Erlang (see http://www.satine.org/archives/2007/12/13/amazon-simpledb/).

@Jon,

For a different approach to a SSDS client that runs REST and SOAP (and compares performance), see http://oakleafblog.blogspot.com/2008/07/updated-sql-server-data-services-ssds.html.

While I think “eventual consistency” will surprise a lot of developers as they build applications, I understand the trade-offs. Question is whether most developers understand the differences and the trade-offs between “consistent” and “eventually consistent”. I think there is place for both but until I hear from actual developers writing real applications, I remain interested to see how this issue evolves.

There is another subtle on as the services are exposed today. SQL Server Data Services (SSDS) supports a few primitive types while string seems to be the only type supported by SimpleDB. It has implications in how predicates are evaluated during filtering and semantics of sort.

BTW,does anyone know what Amazon is using as the underlying engine for SimpleDB? First rumors were that it was Dynamo but I have also heard rumors that it is Berkeley DB.

SSDS is also “actually consistent” instead of “eventually consistent” (like SimpleDB/S3) which makes it applicable to radically different use cases. I’d imagine this was an explicit decision, acknowledging the corresponding tradeoffs, and it will be interesting to see which approach gains more traction.

Correct. And other emerging pieces, notably Live Mesh.

The “continuum of access styles” also applies to ADO.NET Data Services (a.k.a. Astoria) which supports REST queries and JSON or AtomPub wire formats. SSDS’s Web-facing head-end is scheduled to be updated to Astoria standards in a future update.
