The relationship between nginx and web server

nginx is a lightweight, non-blocking web server and reverse proxy, commonly used for front-end proxy, load balancing, and caching. Its relationship with the web server is usually: Front-end proxy: nginx handles the request and forwards it to the back-end server. Load Balancer: nginx distributes requests to multiple backend servers. Caching: nginx caches frequently accessed files for performance.

The relationship between nginx and web server

nginx (pronounced "engine-x") is a high-performance web server and reverse proxy that is often used to serve dynamic web applications. It is known for its speed, stability, high concurrency and low memory footprint.

The difference between nginx and web servers is that:

• Lightweight: nginx is lighter than traditional web servers such as Apache and consumes less system resources.
• Non-blocking: nginx uses a non-blocking I/O model to maintain responsiveness and high performance even under high loads.
• Reverse proxy: In addition to being a web server, nginx can also be used as a reverse proxy to forward requests to the backend server.

The relationship between nginx and a web server is usually as follows:

• Front-end proxy: nginx is located in front of a user-facing web server, processes requests and forwards them to the back-end server according to configuration.
• Load Balancer: nginx can be configured to distribute requests to multiple backend servers for greater availability and scalability.
• Caching: nginx can cache frequently accessed files (such as images and CSS) into memory for improved performance.

Common nginx and web server combinations include:

• nginx Apache
• nginx Nginx
• nginx Tomcat

In these configurations, nginx is usually responsible for handling front-end requests and reverse proxying, while web servers such as Apache or Tomcat are responsible for handling application logic and content generation.
