Why is the Nginx server used for the main domain?

Nginx is often used as a reverse proxy server for the main domain for several reasons:

• Load Balancing: Nginx can distribute incoming requests among multiple instances of a Go application, ensuring scalability.
• Static File Handling: Nginx efficiently serves static resources (CSS, JS, images), offloading the application.
• Security: Nginx can act as a protective layer, filtering requests, restricting access, and providing SSL termination.
• Caching: Nginx can cache responses, reducing the load on the backend.
• Connection Management: Nginx handles a large number of concurrent connections more effectively.

Thus, using Nginx in front of a Go application enhances performance, security, and server management convenience.
