3. Design Standards
3.1 Architecture Principles
Microservices architecture with independent scaling per service.
Event-driven integration engine using message queues for reliability.
API-first design — all features accessible via documented REST API.
Stateless processing — no customer business data stored beyond the sync window.
Multi-tenant isolation — each customer’s data and configuration fully segregated.
3.2 Security-by-Design Requirements
Threat modelling conducted at design phase for all new data flows.
PII fields identified and masked at design time before implementation begins.
Credential storage reviewed by security team before any connector goes to production.
All new API endpoints require authentication — no anonymous endpoints permitted.
