Experiences scaling a modular monolith to microservices using the 4+1 views
summary
Start by mapping bounded contexts in the logical view and treat those boundaries as the true units of autonomy; enforce inter-context communication via message queue even when contexts run in the same process. Begin with a single repo and small team—use a monorepo with path-based CI to produce separate artifacts—then extract processes or containers only when queues, latency or priority needs demand it. Also segregate data and disk layout, modularize tests per context, and let developer, process and physical views evolve independently.
