Building a Spring Boot application that works on your laptop is one thing. Building one that survives production traffic, resists attacks, and gracefully handles failures is something else entirely. This course bridges that gap. It takes you beyond basic CRUD into the real-world challenges of secure, resilient, scalable system design. You'll implement OAuth2 authentication, circuit breakers, rate limiting, and API gateways—all with production-ready code. If you're ready to build systems that don't just work, but thrive under pressure, this is the course for you.

This Course Offers

• Complete Secure Authentication and Authorization: Implement OAuth 2.0, OpenID Connect, and JWT in practice, integrate Identity Providers with Auth0, and configure Spring Security for real applications.
• Production Resilience Patterns: Master Resilience4j for circuit breakers, retry logic, time limiters, rate limiters, and bulkhead patterns that prevent cascading failures.
• API Protection and Scalability: Implement rate limiting with Bucket4j and Resilience4j, configure API Gateway patterns with Spring Cloud Gateway, and master load balancing strategies.
• Spring Boot Monitoring and Configuration: Use Spring Boot Actuator for live metrics, manage environment-specific configurations, and customize TLS, context paths, and logging levels.
• Two Annex Sections for Fundamentals: If you're new to Spring Boot or Spring Security, dedicated sections bring you up to speed before the advanced material.

Why We Love This Course

1. It focuses on production realities, not toy examples. This isn't another CRUD tutorial. It's about building systems that survive load, failure, and attack.
2. The resilience patterns coverage is exceptional. Circuit breakers, retries, bulkheads—these are the patterns that keep distributed systems alive, and you'll implement them all.
3. It's designed for serious backend engineers. Whether you're in Java, Node.js, Python, or Go, the design principles apply universally.
4. The live coding sessions are invaluable. Watching production patterns implemented in real time builds understanding that reading alone can't provide.

Modern backend development demands more than just working code. It demands systems that are secure by default, resilient to failure, and ready to scale. This course gives you the patterns, practices, and code to build them.

• Java developers who want to go beyond CRUD and build production-grade systems that survive real-world conditions.
• Backend engineers aiming to design secure and fault-tolerant APIs with industry-standard patterns.
• Spring Boot users looking to deepen their understanding of Spring Security and Resilience4j for resilient systems.
• Software developers preparing for roles in microservices or cloud-native architectures.
• Engineers interested in mastering OAuth2, OpenID Connect, and API protection patterns.
• Developers seeking to implement real-world resilience patterns like retries and circuit breakers.
• Tech leads and architects responsible for system reliability and scalability.
• DevOps-minded engineers who care about observability, rate limiting, and system hardening.
• Anyone building Java-based distributed systems wanting practical guidance on robust design.
• Developers from other languages (Node.js, Python, Go) wanting to learn backend best practices via Spring Boot.

• Basic knowledge of Java programming.
• Familiarity with object-oriented programming concepts.
• Some experience working with Spring Framework (recommended but can be learned during the course too).
• Understanding of RESTful APIs and HTTP fundamentals.
• Basic knowledge of Maven or Gradle build tools.
• Comfortable using an IDE like IntelliJ IDEA or Eclipse.
• No prior experience with Resilience4j, Auth0, or OAuth2 required—all will be explained in the course.
