Nginx (pronunciation: / EN-jin-EKS), stylized as (NGINX, NGiИX or nginx), is a web server, which can also be used as a reverse proxy, load balancer and HTTP cache.
Created by Igor Sysoev in 2004, it runs on Unix, Linux, BSD variants, macOS, Solaris, AIX, HP-UX, and Windows.
Igor Sysoev began development of Nginx in 2002. Originally, Nginx was developed to solve the C10K Problem, and to fill the needs of websites including Rambler, for which it was serving 500 million requests per day by September 2008.
Nginx is free and open source software, released under the terms of a BSD-like license. A company of the same name was founded in 2011 to provide support.
