Design for Scalability, Resilience, and Extensibility

Design for Scalability, Resilience, and Extensibility¶

Define how the system scales across tiers and regions¶

Tasks:¶

• Document scaling strategies in service READMEs
• Add scalability validation to architecture reviews
• Set up load test thresholds to simulate scale
• Review scaling requirements with infrastructure team

Ensure components are loosely coupled and easily extensible¶

Tasks:¶

• Define and publish public interfaces in each repo
• Add extensibility checklist to design docs
• Use feature flags for early code paths
• Review extensibility in design review
