The Biggest Impact of Microservices: We Now Think Smaller

The shift towards microservices in software architecture emphasizes the importance of smaller, modular codebases that enhance both organizational efficiency and software maintainability. A recent workshop highlighted that while microservices present challenges such as managing service boundaries, containerization, and distributed transactions, they encourage a focus on low coupling and high cohesion, revisiting core modular software principles. Clear boundaries, often achieved through domain-driven design, reduce cognitive load and limit the impact of changes across the codebase. Additionally, smaller components decrease the need for extensive team coordination, thereby increasing development velocity. Ultimately, whether opting for microservices or a well-organized monolithic structure, the emphasis is on thinking smaller to manage complexity and improve software development processes.
