Yeah, there are trial accounts and things but as far as I know, none of the big cloud providers have a way to say "Under no circumstances are you to charge me for than $X per month even if it means shutting down services."

A lot of Chinese cloud providers like Aliyun will only allow pay and go, because there’s no way to recursively bill

My own instances go down all the time when I forget to ‘top up’ the account

Yeah I see that too I'll add that to my comment tbh I think what I said still stand it's been made hard or maybe said a different way is:

It's very easy to overspend on these big cloud providers

Oh I can't edit the comment now oh well sorry if I've confused anyone.
