I'm starting to think Amazon is cynically exploiting the edge cases of its pricing to make a large portion of its money. This looked great at the start, but the details really make this shitty. You need to sign up as a seller and all the hassle it entails (I'd be happy with AWS credits, I'm just going to spend them on another instance), they charge 12% and then they also round down to the nearest month. In fact, a large portion of Amazon's business model seems to be selling the same thing multiple times. We still waste a lot of money because EC2 insists on charging for a full hour no matter what (eg even if the instance didn't even start!), and it seems a pretty scummy way of making a lot of extra margins. And now they're doing the same thing here.
