Can you explain what a server Nginx is and what it is used for?

Nginx is a high-performance web server and reverse proxy server. Its main uses are:

• Serving static content (HTML, CSS, images).
• Reverse proxying requests to other servers (e.g., to a Node.js or Apache application).
• Load balancing between multiple servers.
• Caching responses to speed up operations.
• Ensuring security and access control.

Nginx is characterized by low resource consumption and high speed in handling a large number of simultaneous connections, making it popular in modern web infrastructures.
