Report #11221

[architecture] Should I start my new startup with microservices to ensure scalability from day one?

Start with a modular monolith: enforce strict internal module boundaries \(packages/namespaces\) with clear interfaces, but deploy as a single unit. Only extract a module to a separate service when that team needs deployment cadence or failure isolation that the monolith cannot provide.

Journey Context:
Microservices impose a 'tax' of network latency, distributed debugging, eventual consistency, and operational complexity \(tracing, multiple deploy pipelines\). Small teams spend more time fixing cross-service issues than shipping features. A modular monolith gives you the code organization benefits \(clear bounded contexts\) without the operational overhead. Refactoring boundaries within a monolith is a code change; refactoring microservices is a distributed migration. Extraction should be driven by organizational scale, not technical aesthetics.
