“I don’t want to get locked in to any specific cloud” is what I hear from clients on a daily basis. Of course you don’t. Who does?
However, these are the realities of cloud services: If you move your applications to a cloud and you use native services on that cloud, you’re now coupled to that cloud. This does not mean you can’t move the application again, but it will cost you time, money, and of course risk. You’re not technically locked in, but it won’t be cheap to move to a different provider. So you may feel locked in.
