nginx

Nginx is a powerful and popular open-source web server software. It is also used as a reverse proxy server, load balancer, HTTP cache, and mail proxy. Nginx was created in 2004 by Igor Sysoev, with the goal of solving the C10k problem and providing better performance for high-traffic websites. It is known for its efficiency, scalability, and ability to handle concurrent connections with low memory usage. Nginx uses an asynchronous, event-driven architecture called the event-driven model, which allows it to handle many connections simultaneously with minimal system resources. It supports various protocols such as HTTP, HTTPS, HTTP/2, SMTP, and POP3. Nginx can be easily configured using its configuration file, which allows users to customize its behavior according to specific needs. With its modular design, Nginx can be extended with various modules to add additional features and functionality. It is often employed as a front-end or proxy server to handle requests and distribute traffic to multiple backend servers. Nginx has gained significant popularity among web developers and system administrators due to its speed, reliability, and extensive feature set.
