This network diagram represents the complete architecture of a modern web application. It shows users accessing the application through web browsers or mobile apps via HTTPS, passing through the internet, DNS/CDN, firewall, and load balancer. The traffic then reaches web servers hosted in the DMZ zone, which communicate with application servers and cache servers in the application layer. Database servers and backup monitoring systems manage data in the backend. The diagram demonstrates secure connections using ports like TCP 443 and SQL 3306, emphasizing performance, scalability, and security in a multi-layered web application infrastructure.
