How to separate hosting of Backendless app content from static web content?

Thank you. The “Tiered Pricing” page is very informative.

Is there a safety feature I can enable to deny requests beyond a certain tier?
By “deny” I mean - throttle, queue, or stagger timing of API requests,
in order to safeguard against unexpectedly high fees.

Without such a feature I think it will be difficult to anticipate how high the cost of running the app will be.

Since I don’t see any mention of such a safety cap, I’m going to make a separate post about it as a suggestion.
(The reply I was drafting grew longer than I expected, and has become a topic of its own.)
If it turns out that such a feature already exists, feel free to disregard my suggestion.

Here is the feature suggestion post:
