Cross-border logistics platform with multi-layered architecture integrating user, platform, integration, and data layers to manage suppliers, customers, warehousing, and customs clearance. Traffic flows through Internet → WAF → CDN → API Gateway, which routes requests to supplier portals, customer apps, product catalogs, and backend management systems with Auth/SSO protection. Core services include order management, warehouse operations (WMS), customs integration via Octopus system, and event-driven workflows powered by message queues and event buses. This architecture demonstrates enterprise-grade separation of concerns, enabling independent scaling of user-facing services, business logic, integration middleware, and persistent data stores. Fork and customize this diagram on Diagrams.so to adapt the pattern for your logistics, supply chain, or multi-tenant SaaS platform. The design supports high availability through CDN caching, Redis caching, and asynchronous processing via MQ and workflow engines.
