In today's complex, interconnected microservices architecture, network failures, resource constraints, and external system unavailability can interrupt seamless data flow, causing APIs to fail. API failures in microservices can hinder application performance and impact user experience. Understanding effective retry mechanisms becomes essential to ensure resilience and improve service reliability. But implementing retries requires careful thought; done incorrectly, retries can cause more harm than good. In this article, we’ll explore retry strategies, coding best practices, and considerations around their deployment, examining the entire retry process in detail.
