Nginx (pronounced “engine X”) is a lightweight web server, reverse proxy server, and email (IMAP/POP3) proxy server, released under a BSD-like license. It was developed by Russian programmer Igor Sysoev and originally used by Rambler (Russian: Рамблер), a major Russian web portal and search engine. Its key advantages are low memory consumption and high concurrency performance — in fact, Nginx’s concurrency handling is among the best in its class for web servers of this type. Currently, major websites in mainland China using Nginx include Sina, NetEase, and Tencent. Additionally, the well-known microblogging platform Plurk also runs on Nginx.
