Multi-tier student registration form architecture separates concerns across presentation, application, and data layers using Nginx, PHP-FPM, and MariaDB. Student requests flow through Nginx in the DMZ to PHP-FPM backend services in the LAN, where validation and authentication occur before database writes. This layered design enforces security boundaries, enables independent scaling, and simplifies maintenance of registration workflows.
