Migrating Monoliths to Microservices: Architecture and Strategies

Transitioning a legacy monolithic application to a distributed system can feel overwhelming without a clear roadmap. This text-based course guides you through the essential concepts and practical strategies needed to plan and execute a successful microservices migration. You will transition from understanding basic software design to confidently evaluating, planning, and executing migration patterns. You will learn how to break down a monolith systematically while maintaining system stability, secure communication, and operational visibility. What you'll learn: Understand foundational microservices terminology, core architectural patterns, and the trade-offs of distributed systems; Apply proven migration patterns, such as the Strangler Fig pattern, to safely decompose monolithic codebases; Configure secure communication pathways using modern API gateways, JWT authentication, and service-to-service protocols; Design data migration strategies that maintain data integrity and handle shared databases during transition phases; Implement modern observability concepts like distributed tracing to monitor your services during and after migration. The course begins with foundational architectural concepts and definitions before moving into step-by-step migration methodologies, communication design, security protocols, and real-world transition scenarios. This course is designed for software developers, system architects, and technical project managers who are new to microservices migration and want a clear, conceptual framework without complex prerequisites.
