Report #60892

[architecture] Premature service decomposition causing operational toil and distributed complexity for small teams

Adopt a Modular Monolith: deploy as a single unit but enforce strict internal boundaries using compiler/module systems \(e.g., Java modules, Go internal packages, C\# internal visibility, TypeScript project references\). Define explicit APIs between modules \(internal REST/gRPC or in-process interfaces\) and forbid direct database access across module boundaries—each module owns its schema tables. Extract to separate services only when a module requires independent scaling, deployment cadence, or team ownership.

Journey Context:
Small teams \(<10 developers\) adopting microservices face 'death by a thousand papercuts': distributed tracing, multiple deployment pipelines, service discovery, contract testing, and cascading failures. The 'Monolith First' approach is often interpreted as 'spaghetti monolith'—but the missing piece is \*enforced modularity\*. Without compiler/static analysis preventing cross-module imports, the monolith becomes a 'big ball of mud'. The Modular Monolith provides the operational simplicity of single-unit deployment with the organizational benefits of clear boundaries. Extraction later becomes 'changing the wire protocol' rather than 'refactoring the codebase'.
