Spring Boot & Resilience4j | Mastering Circuit Breakers with Prometheus and Grafana
A comprehensive guide to implementing resilient microservices: from basic circuit breaker patterns to advanced monitoring with Prometheus and Grafana
As app becomes more distributed, service — to — service communication failures are at a greater risk. In this, I will explain the circuit breaker pattern and how to put in place in your Spring Boot application.
Introduction
Imagine you’re building a microservice — based application where many services depend on each other. What happens when one service strt failing? Without proper error handling, failures can cascade through your system. They could bring down the entire application. This is where circuit breaker pattern comes in.
Understanding the circuit breaker pattern
Michael Nygard popularized the circuit breaker pattern in “Release It!”. It prevents cascading failures and provide a fallback when integrations fail. It works like an electrical circuit breaker — when it detects a problem, it stops the flow to protect the system.
