What This Course Covers

Core Resilience Patterns

• Circuit breaker fundamentals and configuration with Resilience4j.
• Retry policies for handling transient service errors.
• Time‑limiter usage to avoid backend hangs and long response times.
• Bulkhead isolation techniques using thread‑pool and semaphore models.

Spring Cloud Integration

• Setting up Spring Cloud LoadBalancer for client‑side load distribution.
• Configuring Spring Cloud Gateway for routing, edge protection, and API composition.
• Implementing rate limiting with Bucket4j integrated into gateway filters.

Security & Authentication

• Securing microservice endpoints with OAuth2 and JWT tokens.
• Integrating Spring Security for role‑based access control.
• Connecting external identity providers such as Auth0 for production‑grade authentication.

Observability & Testing

• Using Spring Boot Actuator to expose health, metrics, and trace endpoints.
• Writing integration tests for resilient endpoints with MockMvc and Testcontainers.
• Monitoring fault‑tolerant asynchronous flows using CompletableFuture and TimeLimiter.

Comparative Library Review

• Detailed comparison of Resilience4j versus Bucket4j feature sets.
• Decision matrix for selecting the right library based on latency, throughput, and complexity.
• Real‑world case studies illustrating library choice in high‑traffic environments.

Hands‑On Projects

• Building a secure, production‑ready microservice from scratch.
• Deploying a fault‑tolerant API that gracefully recovers from downstream failures.
• Implementing load‑balanced services with automatic failover across multiple instances.

Who Should Take This Course
