Also DynamoDB (vs MongoDB)

Instead of DynamoDB, perhaps you meant DocumentDB which is AWS's managed MongoDB compatible database service.

Whoops, right! Hard to keep track of all those AWS services

I think you mean DocumentDB, not DynamoDB.

Not quite the same situation. Amazon published the original Dynamo whitepaper with DynamoDB being a non-opensource implementation. Many other NoSQL datastores were built since the whitepaper's publication in 2007.
