[architecture] Adopting microservices prematurely for small teams, creating operational complexity and distributed debugging nightmares

Start with modular monolith \(Majestic Monolith\) using internal modular boundaries \(ports/adapters\); extract services only when subdomains require independent deployment cadence, scale, or tech stacks, and team size exceeds ~8-10 engineers

Journey Context:
Microservices solve organizational scaling problems, not technical ones. Small teams adopting them incur 'microservice premium': distributed tracing complexity, deployment orchestration, eventual consistency debugging, integration testing overhead, and network latency. The 'modular monolith' keeps code separated \(hexagonal architecture\) while deploying as single unit, preserving refactoring ability. Extract a service only when: \(1\) different teams need to deploy independently \(Conway's Law\), \(2\) component needs scale orthogonal to rest, or \(3\) requires different language runtime. Premature extraction creates 'distributed monolith'—worst of both worlds: network latency with tight coupling. Most 'microservices' should start as modules.
