I would not touch this with a 10-foot pole. A few weeks ago Larry Page was asked about "putting the user first" at TGIF. His solution to this problem is to go mobile only and dedicate 80% of the company's resources to mobile (at the expense of everything else)
Do you think Google is going to care about things like this with there new strategy? If you're business depends on any cloud provider do yourself a favor and go with AWS, you'll end up in a much better position then if you went with Google.
