I have only good things to say about AWS. I once got $2500 of credit from them for a research grant, and left the servers running after the project ended and ran up about $600 extra. At this point, I was no longer in the lab, but still a student and had no way to pay an extra $600. AWS wrote off the entire cost, despite this being totally my mistake.
