What is Circuit Breaker?
A pattern that stops calling a failing service temporarily to prevent cascading failures.
Why It Matters
Circuit breakers prevent a single failing service from taking down your entire application.
Real-World Example
If the payment service fails 10 times in a row, the circuit breaker stops calling it for 30 seconds and returns a friendly error.
“Understanding terms like Circuit Breaker matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
