Layered news portal architecture combining a React frontend, Node.js Express API, and SQLite database with Nginx reverse proxy, WAF, and CDN for security and performance. Browser clients route through WAF and CDN to Nginx, which distributes requests to the React Frontend and Node.js + Express API layers. The Node.js + Express API handles business logic and database operations against SQLite 3, demonstrating separation of concerns across presentation, application, and data tiers. Fork this diagram on Diagrams.so to customize security policies, add load balancing, or swap SQLite for PostgreSQL. This architecture balances simplicity with production-ready patterns like reverse proxying and content delivery.
