I wonder how much of the cloud provider revenue comes from situations like this. I suspect quite a lot.

I think that the cloud provider business model that allows for uncapped maximum costs is a bit of a commercial dark pattern. What makes it somewhat more nefarious is that it is relatively easy to blame the customer.

I’m not surprised that the cloud providers are quick to refund users as it’s likely that they only do it in a fraction of cases and it buys a lot of goodwill.

It would be interesting to try and design a cloud that supports OutOfMoneyException’s with gradual degradation and capped liability for costs built in.
