Bulkhead pattern is one of my favorites.

Even with a monolith, often one can spin up multiple copies, and assign different routes in a front end http proxy to different copies of the monolith.

It makes it extremely clear which endpoints are consuming how much resources. And if one copy goes down, the others are ok.

Absolutely one of the best things you can do, not just for protecting against faults, buy also for understanding the cost of different endpoints.
