Just one thing: credit card. Once they have all details, they can do whatever they want with you. They can let you go - but that's only their good will. Personally I'm in love with Hetzner cloud. It has less "features" (=proprietary complexity) than AWS/Azure, but I can understand everything perfectly and, most importantly, I have a guarantee I won't be charged over a limit.
