- 1. Common Failure Modes in Microservices Architecture Identifying and Mitigating System Weaknesses +91-7032290546
- 2. Introduction to Microservices Definition: Microservices is an architectural style that structures an application as a collection of loosely coupled services. Benefits: Scalability, independent deployment, faster time to market. • Challenge: While flexible, microservices introduce new types of failure modes. www.visualpath.in +91-7032290546
- 3. Service-to-Service Communication Failures Description: Microservices often rely on synchronous or asynchronous communication. Failures: o Network latency or timeout o Service unavailability o Misconfigured endpoints Impact: Cascading failures, poor performance • Mitigation: Timeouts, retries, circuit breakers (e.g., Hystrix) www.visualpath.in +91-7032290546
- 4. Data Inconsistency & Distributed Transactions Issue: Each service may manage its own database, making global consistency hard. Failures: o Partial updates o Lost or duplicated messages o Dirty reads/writes • Mitigation: Saga patterns, eventual consistency, idempotent operations www.visualpath.in +91-7032290546
- 5. Dependency Failures Cause: One service depends on another (e.g., payment -> inventory -> shipping). Failures: o Downstream service crashes o Version mismatch Mitigation: o Graceful degradation o API versioning • Fallback strategies www.visualpath.in +91-7032290546
- 6. Service Discovery & Load Balancing Failures Issue: Microservices require dynamic discovery and load distribution. Failures: o Stale service registry o DNS misconfiguration o Load balancer bottlenecks Mitigation: o Health checks • Self-healing service registries (e.g., Consul, Eureka) www.visualpath.in +91-7032290546
- 7. Configuration & Deployment Failures Cause: Each service has its own configuration, often stored centrally. Failures: o Incorrect config values o Misconfigured secrets or credentials o Inconsistent deployment pipelines Mitigation: o Configuration management tools (e.g., Spring Cloud Config) o Canary deployments • CI/CD with automated rollback www.visualpath.in +91-7032290546
- 8. Observability & Debugging Challenges Issue: With many services, tracing the source of a failure is difficult. Failures: o Lack of centralized logging o No correlation IDs o Poor metrics/alerts Mitigation: o Distributed tracing (e.g., OpenTelemetry, Jaeger) o Centralized logging (e.g., ELK Stack) • Monitoring dashboards (e.g., Prometheus, Grafana) www.visualpath.in +91-7032290546
- 9. Conclusion & Best Practices Summary: o Microservices offer flexibility but introduce new failure modes. o Resilience patterns and observability are key to success. Best Practices: o Design for failure o Automate monitoring and recovery o Regularly test failure scenarios (chaos engineering) • Final Thought: "Build systems that fail gracefully, not ones that never fail." www.visualpath.in +91-7032290546
