What is Circuit Breaker Design Pattern in Microservices? Spring Cloud Netflix Hystrix Example in Java?

Learn how to use Netflix Hystrix to create a circuit breaker in Java Microservices and prevent cascading failures.

In today’s world of Microservices architecture, ensuring the resilience and fault tolerance of your system is critical. One way to achieve this is through the Circuit Breaker design pattern, one of the 10 essential Microservice design pattern, which allows you to detect and recover from failures in external services.

In the past, I have shared Microservices design principles and best practices as well as explained SAGA, CQRS, Load Balancer, and API Gateway pattern in detail and in this article, I will explain what is Circuit breaker design pattern and what problem does it solve.

We’ll take a closer look at the Circuit Breaker pattern and explore how to implement it in Java using Spring Cloud Netflix Hystrix. By the end of this article, you’ll have a better understanding of how to improve the resilience of your microservices architecture using the Circuit Breaker pattern.

The Circuit Breaker pattern is a design pattern used in distributed systems to prevent cascading failures when one or more services fail. The…
