Curriculum Highlights
-
Key Topics Covered:
- Resilience in microservice architecture (theory & importance)
- Resilience4j setup & Spring Boot integration
- Circuit breakers (preventing cascading failures)
- Retry mechanisms (recovering from transient errors)
- Rate limiting (API protection from overload/abuse)
- Time limiters (avoiding slow responses/hangs)
- Bulkhead patterns (failure containment via resource isolation)
- Fallback strategies (graceful degradation)
- Configuration via
application.properties - Monitoring with Spring Boot Actuator
- Integration testing for fault-tolerant endpoints
- Chaining Resilience4j decorators (e.g., retry + circuit breaker)
