There's also ones that aren't in active development like SimpleDb. It's not that it doesn't work, but you probably don't want to build anything new with it.
I don't get this attitude when applied to small things. Can't it just be considered complete and not in need of enhancements? If it's not supported to the point of not fixing security issues that's completely valid.
SimpleDB has some significant limitations which don't exist in its successor, DynamoDB. For example, SimpleDB tables are limited to a size of 10 GB; no such limitation exists in DynamoDB.
Well stated. It's very clear to say it has a 10 GB limit rather than a vague "don't use this". SimpleDB and DynamoDB are at opposite ends of the scaling spectrum.
I actually agree with this in general. One of the open questions in my mind is what's a single-product business supposed to do when its product is feature complete.
