Well, there are some very good comments in this thread, very little to add. All of those plans that I compare there use the same technology in the the end, KVM virtualization. The differences are in the "flexibility" and "services" that they offer in order to act more as a cloud or more as a classic VPS. But the lines are very blurred these days. You can almost achieve the same things with any of them in these kind of plans. IMHO I think that you can really start talking about clouds when you're playing in the same league as AWS, Google Cloud and Azure.
