[architecture] Deciding between monolith and microservices for small teams

Keep a modular monolith until the team grows beyond 8-10 developers or requires independent deploy scaling; never split into 'microservices' that share a database \(distributed monolith anti-pattern\).

Journey Context:
Small teams \(<5 devs\) often prematurely split into microservices to be 'modern,' incurring network latency, deployment complexity, and debugging nightmares without gaining team autonomy. The worst case is services A and B sharing a database table, requiring coordinated deploys—a distributed monolith with all costs and no benefits. Extract a service only when \(1\) deployment independence is required, \(2\) schema isolation is maintained, and \(3\) clear team ownership exists.
