Nginx

Nginx (pronounced “engine-x”) is a popular open-source web server that can also be used as a reverse proxy, load balancer, mail proxy, and HTTP cache.

Key Features

• High Performance: Capable of handling a high volume of concurrent connections.
• Reverse Proxy: Directs client requests to the appropriate backend server.
• Load Balancing: Distributes incoming traffic across multiple servers (e.g., Round Robin, Least Connections, IP Hash).
• Static Content Serving: Extremely efficient at serving static files like HTML, CSS, JavaScript, and images.

It is widely used in modern web architectures to ensure high availability and reliability.
