• 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

Your microservices are deployed. Your APIs are live. But will they survive?

Modern applications don’t fail because of bugs – they fail because they can’t handle traffic spikes, dependency timeouts, or unexpected downtime in connected services. That’s why top engineers today are turning to resilience patterns – to build systems that don’t just run, but endure.

In this hands-on course, you’ll master the core resilience patterns that protect real-world systems – including circuit breakers, retries, time limiters, rate limiters, bulkheads, and load balancing – all using Spring Boot, Resilience4j, and Spring Cloud.

You won’t just learn how to implement them – you’ll understand when, why, and where to use each pattern, with real coding demos, architectural reasoning, and battle-tested practices.

What You’ll Build:

• Secure, production-ready microservices

• Fault-tolerant APIs that gracefully recover from failures

• Scalable backends that handle real-world traffic and instability

• Rate-limited endpoints that protect your services from abuse

• Load-balanced systems with automatic instance failover

Why This Course?

This isn’t theory. This is real-world engineering.

You’ll work with:

• Resilience4j, the industry-standard lightweight fault tolerance library

• Spring Cloud Gateway for routing and edge protection

• Spring Security & OAuth2 to protect your APIs

• Spring Boot Actuator to monitor and measure application health

We go beyond simple REST apps and teach you how to survive in today’s cloud-native, distributed architecture world.

Who This Is For:

• Software Engineers building or maintaining microservices

• Backend engineers preparing for real production deployments

• Spring Boot developers wanting to upgrade their architecture skills

• Software architects and tech leads focused on uptime, performance, and reliability

• Anyone working with distributed systems who wants to prevent cascading failures

By the end of this course, you won’t just know what resilience is – you’ll know how to build it into everything you write.

Enroll now and start building microservices that can take a hit – and keep running.
