To design scalable system architecture, outline domains, components, and boundaries for frontend, backend, auth, and data stores. This approach ties each major component to a concrete product need while keeping solutions simple and avoiding unnecessary distributed complexity.

Choose a monolith over modular services when keeping solutions simple and avoiding unnecessary distributed complexity aligns with your team size and operational constraints. Your deployment and modularity decisions must always be justified by concrete product needs and tradeoffs.

Defining system boundaries involves outlining frontend, backend, auth, data stores, jobs, and external systems with responsible components. It ensures aligned boundaries and clear ownership across the architecture, fitting the product scope and team reality.

Identify observability needs and failure modes by applying architecture validation to your system design. This process flags scale concerns and operational risks early, guiding implementation to ensure the cohesive architecture handles expected failure modes effectively.

System architecture often includes unnecessary distributed complexity when components are not tied to concrete product needs. Enforcing constraints like keeping solutions simple and aligning deployment models with actual team size prevents over-engineering and maintains cohesive boundaries.
