Nginx: High-Performance Web Server for Scalability and Reliability

Nginx (pronounced 'engine-x') is an open-source web server software used to serve web pages and applications with high performance, reliability, and scalability. Known for its low resource utilization and ability to handle a large number of concurrent connections, Nginx was originally developed to address the C10K problem, the challenge of handling 10,000 or more concurrent connections to a web server. It is often used as a reverse proxy, load balancer, and HTTP cache to improve the performance and availability of web applications. Nginx is widely used by many popular websites and web applications, including Netflix, Airbnb, Pinterest, and GitHub.
