Today's episode examines several resilience patterns crucial for building robust microservices architectures. It begins by emphasizing that failures are expected in distributed systems and introduces the core principles of resilience and reliability, such as designing for failure and observability. The document then focuses on three specific patterns: the Retry Pattern for handling transient errors, detailing its benefits, trade-offs, and implementations; the Circuit Breaker Pattern for preventing cascading failures by stopping calls to unhealthy services, explaining its states and operational considerations; and the Bulkhead Pattern for isolating components to limit the impact of failures, discussing its uses and implementation strategies across various platforms.
