Microservices solve organizational problems more than technical ones. Starting with a well-structured modular monolith is recommended over premature service splitting. Tight coupling persists even when services communicate over HTTP instead of function calls. Key warning signs include excessive inter-service calls and frequent cross-service changes. Event storming helps identify proper boundaries by mapping domain events and behaviors. Sometimes merging tightly coupled microservices back together is the right solution. Team structure should drive architecture decisions (reverse Conway maneuver), not the other way around.
