Introduction to Microservices: Designing Distributed Systems

Transitioning from a single, large codebase to a distributed network of independent services is one of the most critical shifts in modern software engineering. This text-based course guides you through the foundational principles of microservices, helping you understand when to adopt this architecture and how to avoid common design pitfalls. You will move from thinking in monolithic terms to planning modular, resilient, and independent services. Through structured written explanations, architectural breakdowns, and practical scenarios, you will gain the knowledge to design and implement robust distributed systems. What you'll learn: - Compare monolithic and microservices architectures to make informed design decisions for your applications. - Decompose a system into cohesive, independent services using domain-driven design principles. - Establish reliable communication between services using synchronous APIs and asynchronous event-driven patterns. - Understand the role of API gateways, service discovery, and basic containerization in modern deployments. - Apply essential observability practices, including distributed tracing and structured logging, to monitor system health. - Manage data consistency across distributed databases using modern transaction patterns. The course begins with key terminology, architectural foundations, and a detailed comparison of system designs. It then progresses step-by-step through communication protocols, data management strategies, and deployment fundamentals. Designed for beginner developers, software engineers, and system architects who are new to distributed systems, this course requires no prior microservices experience.
