Slightly OT, but Can you move your business from your current cloud provider, to another one? I have a simple life, simple requirements, I roll all my own services, I hope I can. I went to an AWS seminar targeting start ups in my City and I was reminded of Tom Lehrer: "He gives the kids free samples because he knows full well that today's young, innocent faces will be tomorrow's clientele" They were very keen for us to build businesses on their proprietary systems, which would be "free". Once you have built your business on the proprietary services and APIs of AWS, Azue, or whomsoever, they have a lot of power over you. In my experience the mistake that costs a lot and is most often made is to ignore portability.
