Google Cloud is the least geo-distributed provider around. Which is a major problem if your use case has requirements around (a) latency and (b) data locality due to legal requirements.

In 2017 they will finally have datacenters in Sydney, London, Singapore, Frankfurt etc.

This is one area where Azure is leading with both Azure SQL and DocumentDB supporting geo-replication.

nope since azure is extremly expensive and also you need several accounts for different regions. i.e. you can't create servers in germany with a whole new account / credits / support.

This is about capabilities, not price. Azure Germany is the only one that requires a different account due to German legal issues. The rest of the datacenters are all connected from the same account.

That's because Azure in Germany is not offered by Microsoft but T-Systems. Microsoft just supplies the tech. For the other regions one account suffices (I'm not sure about China where they also use a partner).
