🧩 Microservices Decoded: Design Scalable Systems with Confidence
🧾 Course Description
Microservices architecture is the backbone of modern enterprise and cloud-native systems. In “Microservices Decoded”, you’ll learn how to design, build, and deploy distributed applications that are scalable, resilient, and independently deployable.
This course covers everything from breaking a monolith into services, communication strategies, service discovery, and inter-service security — all explained with real-world scenarios, design patterns, and optional implementation using Spring Boot, Docker, and API Gateway.
Whether you’re a developer, architect, or DevOps professional, this course will give you the conceptual clarity and system-level thinking needed to excel in a microservices environment.
✅ Key Benefits
- 🧠 Think in Systems, Not Scripts — Learn to design modular, scalable architectures
- 🔗 Build for Independence — Avoid bottlenecks by decoupling services
- 📦 Polyglot Flexibility — Use the best tech stack for each service
- 🚀 Deploy Faster & Smarter — Improve delivery with independent pipelines
- 💥 Resilience by Design — Handle failures, retries, and distributed state like a pro
🎯 Pre-requisites
- Solid understanding of REST APIs, HTTP, and basic backend development
- Familiarity with Java (Spring Boot) or any web framework (Node.js, Python, etc.)
- Basic knowledge of Docker, Git, and CI/CD concepts recommended
- Optional: exposure to monolithic app structure

🧪 Module 7: Practical Microservice Project (Spring Boot-based)
- Build 3 microservices (e.g., User, Order, Inventory)
- Use REST communication
- Add service registry + config server + gateway
- Include fault tolerance (Hystrix/resilience4j)
- Deploy using Docker + Docker Compose
