This all being said, I'm a generally happy AWS admin... What happened really can't be blamed squarely on anyone... AWS can't show us a bill since they don't bill us.. the 3rd party probably could have helped with the bill alerts before the incident, but they did help after... Also couldn't really expect AWS to provide more credits to cover lost credits they already provided to help us get off the ground. Overall we really wouldn't be able to do what we do with any on prem solution.
