Many comments say it cant be done, but this is disingenious. As if we were bureaucrats with no imagination:

Eg just have 2 caps: First cap triggers a red alarm prohibiting provisioning, or storing, of new data. The second one (when you are like 50% above the first cap) is dark red, closing down everything except storage.

Sure, decisions have to be made for every single service, but you don’t need a perfect solution if it is optional.

Eg, you could start ONLY with EC2 and will have fixed 50% of the problem.
