Self-Contained Systems: Designing Independent Microservices and UIs

Traditional microservices often struggle with frontend integration and data coupling, leading to a complex distributed monolith. Self-Contained Systems (SCS) solve this by keeping logic, data, and user interfaces together, but implementing them introduces unique architectural challenges. This text-only course guides you through the foundational concepts of SCS, helping you understand how to design, build, and integrate them successfully. By reading through clear explanations and structured architectural examples, you will learn to navigate UI consistency, single-page application (SPA) integration, and mobile app support while maintaining strict team autonomy. You will gain the confidence to make informed design decisions that keep your systems truly independent. What you'll learn: 1. Understand the core principles of Self-Contained Systems and how they differ from standard microservices. 2. Design consistent user interfaces across independent systems using micro-frontends and shared design tokens. 3. Address integration challenges in modern web applications, SPAs, and mobile platforms. 4. Manage data consistency and communication between autonomous systems without tight coupling. 5. Implement modern authentication flows and API gateway patterns tailored for self-contained architectures. 6. Practice evaluating architectural trade-offs through written scenarios and structured design exercises. Starting with fundamental terminology and architectural definitions, the course progresses through real-world integration patterns, UI composition strategies, and security considerations. You will learn how to design systems that scale both technically and organizationally. This course is designed for software developers, aspiring architects, and system designers who are new to self-contained systems. No prior microservices experience is required, as we build up from the absolute basics. Start reading today to master the architectural patterns that keep modern systems truly independent.
