Circuit breakers and retries are resilience patterns that prevent cascading failures in microservices. Circuit breakers stop requests to failing services temporarily, while exponential backoff retries gradually re-attempt calls. Together they isolate faults and allow services to recover without overwhelming downstream dependencies.

The twelve-factor app is a methodology for building scalable, maintainable cloud applications. It enforces separation of codebase, config, and backing services; treats logs as event streams; and ensures stateless processes. This approach enables reliable deployments across containerized and distributed environments.

Design scalable microservices by applying resilience patterns, enforcing configuration management, implementing health checks, and ensuring observability across services. Use bulkheads to isolate failures, circuit breakers to prevent cascades, and structured logging to track system behavior in production.

Yes. Cloud-native patterns apply across containerized applications and distributed systems. Key practices include one process per container, non-root execution, multi-stage builds, and small images. These enforce service isolation, security, and efficient deployments in production environments.

Bulkheads isolate resources to prevent one failure from affecting others. Circuit breakers stop requests to failing services and allow recovery. Retries with exponential backoff re-attempt failed calls gradually. Each addresses different fault-tolerance needs: isolation, fast-fail signaling, and transient error recovery respectively.

Observability and health checks enable early detection of service degradation in distributed systems. Health checks guide load balancing and auto-recovery; structured logging and metrics provide visibility into system behavior. Together they reduce mean-time-to-detection and support automated remediation in production.
