Anything can happen. AWS gives you tools to manage costs, and bill shock stories are usually told by people that didn’t know about those tools. AWS unofficially gives their customers a once-off bill amnesty (within certain not publicly defined parameters) on the proviso that you set up cost alerting properly. I had to play this card at my current employer when I forgot to scale down an RDS instance. They’re very nice about it.
