NGINX is a high-performance web server, reverse proxy, and caching tool developed to address the C10K problem, with its open-source release in 2004 and commercial offerings beginning in 2011. It allows massive scaling for web applications and is optimized for Linux, supporting hundreds of thousands of connections per server without licensing fees. NGINX is the most popular web server for the top 10,000 busiest websites, widely adopted in cloud, dev/ops, and mobile environments.
