Use real-world resilience patterns to build robust, scalable, and failure-resistant backend systems
What you will learn
‘;
}});
Understand the importance of resilience in microservice architecture
Set up and integrate Resilience4j in a Spring Boot application
Implement circuit breakers to prevent cascading service failures
Apply retry mechanisms to recover from transient errors
Use rate limiting to protect APIs from overload and abuse
Implement time limiter patterns to avoid slow responses and hangs
Isolate service calls using bulkhead patterns for failure containment
Create fallback strategies to ensure graceful degradation
Configure and tune resilience patterns via application properties file
Monitor resilience metrics using Spring Boot Actuator
Write integration tests for fault-tolerant endpoints
Chain multiple Resilience4j decorators (retry + circuit breaker, etc.)
Handle exceptions and fallbacks programmatically and declaratively
Build robust and production-ready Java microservices that can withstand real-world failure scenarios
