Abstract: Modern software systems increasingly rely on microservices architectures to deliver scalable, modular, and rapidly evolving applications. As these architectures grow in complexity, individual services and their downstream dependencies become more vulnerable to transient faults, network outages, slow responses, and partial failures. Ensuring system resiliency and the ability to gracefully handle and recover from failures is paramount for delivering a seamless user experience and meeting stringent Service Level Objectives (SLOs). This paper explores key resiliency patterns for microservices, focusing on circuit breakers, retry mechanisms, and backoff strategies. By applying these patterns in conjunction, teams can prevent cascading failures, improve fault isolation, and minimize the negative impact of transient errors. We review the theoretical foundations of these patterns, discuss their implementation details, and present best practices drawn from real-world scenarios. Through examples, pseudo-code, architecture diagrams, and code snippets, we aim to guide DevOps engineers, SREs, and architects in implementing robust failure-handling strategies, ultimately increasing the reliability and availability of complex, distributed microservices ecosystems.
