I don't know, but as NKCSS says, you could do probably that in AWS and being a client like Netflix.

But stressing instances regularly to test them to find a better one is something that you could probably do on your own, but as a service I have serious doubts if the providers would like that from a given scale. I'm not sure, but I don't think that would be something rare to have you account suspended. Perhaps, if you arrive a some type of agreement with them and their "business model" is compatible wit that, maybe. But, don't give me too much credit in this, I'm only speculating.

I can't see it being that much of a problem for the providers, as long as running short-term machines isn't already an issue. You always run the risk that the performance of the machine will degrade over time as the host fills up anyway.
