Microservices Fundamentals: Building Connected Distributed Systems

Modern software engineering relies heavily on microservices architecture to build flexible, scalable applications. Understanding how to decompose monolithic concepts and connect isolated services is essential for modern backend developers. This written course guides you step-by-step through core architectural concepts, design patterns, and practical code implementations for interconnected microservices. You will learn how services interact, handle data, and maintain system stability under real-world conditions. What you will learn: Understand core microservices terminology, domain boundaries, and architectural patterns. Design and build lightweight, independent microservices step-by-step. Implement reliable service-to-service communication using REST APIs and message queues. Apply modern observability practices including structured logging and distributed tracing basics. Configure API gateway routing and service resiliency patterns. Apply clean code conventions and robust error handling across distributed components. The course begins with foundational definitions, architectural trade-offs, and core design principles before guiding you through structured text-based code walkthroughs. This program is ideal for beginner developers and backend learners with basic programming knowledge who want to understand distributed systems.
