You should think about using a circuit breaker pattern when you have a system with multiple services that talk to each

hey everyone, i've been thinking about system resilience lately. we've got a few critical services that depend on each other, and i'm worried about cascading failures if one of them hiccups. i've read about the circuit breaker pattern, but i'm not sure when it actually becomes a necessity versus just a nice-to-have. what are your experiences with implementing circuit breakers? when did you find them most valuable, and what were the biggest challenges
