I Can't say for Azure, but I've used the other two. AWS has SimpleDB, which is in the same ballpark as GAE's datastore, but from personal experience trying to get anything that comes close to resembling transactions from AWS SimpleDB is like taking candy from your own kid, while it's possible, you'll probably regret it later.
In short the GAE datastore rocks in comparison, but offers similar features. Both are, as far as I know, their own unique implementations, though GAE provides the industry standard JDO/DataNucleus interface to it, whereas DataNucleus support for AWS is far less complete, thus you'll have to write data access components specifically for AWS whereas you can come away with fully or near-fully portable code under GAE's datastore.
