I think you may be confusing the issues here, especially if the "well known backend type service" you are referring to is AWS.

I got bit by some undocumented (or at least very poorly documented) hard limits in AWS when our app went viral. It was extremely difficult to just find out what these hard limits actually were. And most importantly, we never explicitly set them, they were just hidden defaults in AWS.

That's very different from having an easy to use, visual dashboard of where and what all your hard limits actually are, and make it it extremely easy to turn them off or on at a moments notice.
