Microservices: Resilience & Observability

Implement the Circuit Breaker pattern using Resilience4j to prevent cascading failures.

Implement fallback strategies and retry mechanisms with exponential backoff.

Implement client-side service discovery and load balancing using Spring Cloud.

Implement centralized configuration for microservices using Spring Cloud Config.

Explain the three pillars of observability (logs, metrics, traces) and the concept of distributed tracing.

Implement distributed tracing in a multi-service application using Micrometer Tracing and Zipkin.

Implement custom application metrics (e.g., counters, timers) using Micrometer and expose them for Prometheus.

Implement structured, correlated logging (including trace IDs) for effective debugging.
