[architecture] Premature microservices causing operational overload and distributed data consistency issues for small teams

Start with a Modular Monolith \(strict internal module boundaries, no shared DB tables\) until team size exceeds 8-10 engineers or deployment cadence varies by >10x between modules.

Journey Context:
Small teams often split services too early to be 'cloud native,' incurring network latency, distributed tracing complexity, and sagas for data consistency without the DevOps bandwidth to manage them. The 'distributed monolith' antipattern emerges: tightly coupled services that must deploy together. The escape hatch is the Modular Monolith: enforce compile-time or package boundaries \(e.g., Java modules, Go packages\) so code is decoupled, but deploy as a single unit. Share a database, but use schema-per-module or strict table ownership \(no FKs across modules\) to enable future split. Only extract a service when a module's scaling characteristics \(CPU/Memory\) or deployment velocity diverges significantly from the core, and you have automated observability \(distributed tracing\) and infrastructure as code already in place.
