Designing Resilient Systems with the Circuit Breaker Pattern
Introduction to Circuit Breaker Pattern The Circuit Breaker pattern is a crucial mechanism for ensuring resilience in distributed systems, particularly in microservices architecture. Inspired by the concept of electrical circuit breakers, this pattern helps prevent cascading failures by detecting when a service is not responding and preventing further requests from reaching it until it becomes available again. Why Use Circuit Breaker? In a typical microservices architecture, multiple services interact with each other. When one service encounters issues such as unavailability or high latency, dependent services may also experience delays or stop responding to requests. This is where the Circuit Breaker pattern comes into play. It detects when a service is in a problematic state and redirects traffic away from it, maintaining system stability. ...
