DDD Architecture Selector

Architecture selection decision guide that evaluates 5 DDD architecture patterns (Layered, Onion, Hexagonal, Clean, COLA) against project context — team size, business complexity, tech stack, infrastructure change frequency, and ecosystem preference.

Workflow

Step 1: Collect Project Context

• Team size & DDD experience level
• Business complexity (simple CRUD / moderate / high)
• Technical stack (Spring Boot / Go / Node.js / .NET / Python)
• Infrastructure change frequency (low / medium / high)
• Multi-entry needs (REST + CLI + MQ + gRPC?)
• Test coverage requirements (unit / integration / E2E)
• Ecosystem preference (Chinese community / international)

Step 2: Run Decision Matrix

• Compare 5 architectures across 7+ dimensions
