Nginx ("engine x") is a high-performance HTTP and reverse proxy server, as well as an IMAP/POP3/SMTP server. Nginx was developed by Igor Sysoev for Russia's second most visited Rambler.ru site. The first public version 0.1.0 was released on October 4, 2004. It releases source code under a BSD-like license and is known for its stability, rich feature set, sample configuration files, and low system resource consumption. On June 1, 2011, nginx 1.0.4 was released.
In the case of high connection concurrency, Nginx is a good substitute for the Apache server: Nginx is one of the software platforms often chosen by bosses in the virtual host business in the United States. Able to support responses of up to 50,000 concurrent connections. Thanks to Nginx for choosing epoll and kqueue as the development model.
