architect

To design a scalable system architecture, you input actual system requirements to enforce architecture principles, evaluate technology stacks, and define a canonical four-layer layout: domain, application, adapter, and infrastructure.

The best way to document technology decisions is by writing Architecture Decision Records (ADRs). This process captures technology selection rationale, enforces architecture principles, and records module decomposition decisions.

Domain-driven design module decomposition works by structuring the system into a canonical four-layer layout: domain, application, adapter, and infrastructure. This enforces architecture principles to improve system maintainability and scalability.

Yes, you can use this approach for technology selection and architecture evaluation. It guides technology stack evaluation, defines architecture principles for new projects, and plans the architecture evolution path simultaneously.

You need to enforce architecture principles during system design when starting new projects, planning module boundaries, or conducting architecture reviews to ensure the resulting system architecture maintains high maintainability and scalability.

A limitation of the canonical four-layer architecture layout is its strict domain, application, adapter, and infrastructure separation. It may require significant upfront technology selection and module decomposition planning for enterprise-scale projects.
