Microservices have become a popular architectural approach for building large-scale, complex systems. While asynchronous communication is often preferred in microservices, there are cases where synchronous communication is necessary. However, relying on synchronous communication introduces challenges related to resilience. This blog post will explore patterns that help make synchronous communication in microservices more resilient, ensuring system stability and fault tolerance.
The Circuit Breaker pattern is a crucial pattern in making synchronous communication in microservices more resilient. It acts as a safety mechanism that monitors the availability and responsiveness of dependent services. The Circuit Breaker maintains a state based on the success or failure of previous requests.
