Distributed systems offer scalability and high availability but come with complexity and risks. Ensuring resiliency is crucial and involves employing downstream and upstream strategies. Downstream patterns include timeouts, circuit breakers, and retries with exponential backoff to handle service failures gracefully. Upstream patterns like load shedding, rate limiting, bulkheads, and health checks with load balancers protect services from overload and ensure stability. Implementing these patterns can significantly enhance the robustness and reliability of distributed systems.
