That sounds better to me than AWS billing, but for personal stuff I'd still prefer to pre-pay and then get cut off if I run out of money in my cloud provider account.
If the provider is worried about incurring costs that they then can't recover, then they could require me to have, e.g., a minimum $10 balance, and all but the simplest of things shut down if I dip below that. Then the remaining ~$10 would be used to pay for cost of storage/bookkeeping, and then if _that_ runs out, they delete all my stuff.
I'm happy to pay. I just can't tolerate much personal risk as an individual with a family.
