Objectives
- Understand the core resilience patterns used in modern microservices
- Implement circuit breakers using Resilience4j in Spring Boot
- Apply retry logic to recover from transient service failures
- Use time limiter patterns to prevent backend hangs and long response times
- Protect APIs with rate limiting using Bucket4j and Resilience4j
- Isolate failures with the bulkhead pattern (thread-pool and semaphore isolation)
- Build load-balanced microservices with Spring Cloud LoadBalancer
- Set up routing and edge protection with Spring Cloud Gateway
- Secure endpoints using OAuth2, JWT, and Spring Security
- Configure identity providers (like Auth0) for real-world authentication
- Monitor service health using Spring Boot Actuator
- Create fault-tolerant asynchronous flows using CompletableFuture and TimeLimiter
- Compare different resilience libraries (Resilience4j vs. Bucket4j) and know when to use each
- Write integration tests for resilient endpoints in Spring Boot
- Design backend systems that stay reliable under pressure and traffic spikes
Pre Requisites
- Basic knowledge of Java programming
- Familiarity with object-oriented programming concepts
- Some experience with Spring Boot (recommended but not mandatory)
- Understanding of RESTful APIs and HTTP methods
- Ability to run Java applications using an IDE like IntelliJ or Eclipse
- Basic familiarity with Maven or Gradle for dependency management
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
