Fault-Tolerant Systems with Resilience4j and Spring Boot

Modern software systems are increasingly reliant on complex dependencies where failures can cascade through services. This course is designed to equip you with the skills to build resilient applications using Resilience4j with Spring Boot. You’ll delve into essential fault tolerance principles and implement strategies that keep your applications available, even under duress.

Through live coding and real-world examples, you’ll acquire practical knowledge to effectively handle network latency, outages, and unexpected traffic spikes. Learn to utilize patterns such as circuit breakers, retries, and bulkheads to ensure your microservices can withstand failures gracefully. This isn’t just theory; it’s your chance to apply these concepts directly to your coding practice and prepare your applications for production-grade challenges.

By the end of the course, you’ll have built and tested robust systems that keep users served, even in adverse conditions. With a focus on hands-on learning, you will not only understand but also apply resilience patterns proficiently using Resilience4j and Spring Boot, preparing you for real-world scenarios where system reliability is paramount.

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
