What gave me the idea that SimpleDB was powered by Dynamo technology: High-availability Key-value store, eventual consistency, targets small objects (< 1MB) that fits SimpleDB item restrictions (max 256 attribute/value pairs and each value < 1KB), and made by the same company. The web service would have to add authentication, enhanced querying, etc. I'm not on a first name basis with Mr. Vogels, so all I can see is the paper and his blog :) On Oct 2, he said Dynamo wasn't directly exposed as a web service. That doesn't preclude Dynamo technology (or related, tweaked-for-web-service software) from being used today for SimpleDB. I think all the Amazon web services have an internal version that's separated from us riff-raff. (I believe that after talking with some Amazon folks at an AWS meeting.) But you are right that it's speculation on my part that the Dynamo paper describes any aspect of SimpleDB.
