Nginx (pronounced "engine-ex") is an open source reverse proxy server for HTTP, HTTPS, SMTP, POP3, and IMAP protocols, as well as a load balancer, HTTP cache, and a web server (origin server). The nginx project started with a strong focus on high concurrency, high performance and low memory usage. It is licensed under the 2-clause BSD-like license and it runs on Linux, BSD variants, Mac OS X, Solaris, AIX, HP-UX, as well as on other *nix flavors. It also has a proof of concept port for Microsoft Windows.[6]

Description

Nginx can be deployed to serve dynamic HTTP content on the network using FastCGI, SCGI handlers for scripts, WSGI application servers or Phusion Passenger module, and it can serve as a software load balancer.[7] Its development started in 2002 by Igor Sysoev.[8] In July 2011, a company was formed as Nginx, Incorporated, registered in the British Virgin Islands. Its principal place of business was San Francisco, California.[9] The company offered commercial support in February 2012.[10][11] An investment of $10 million led by New Enterprise Associates was reported in October 2013.[12] Other investors reportedly included Aaron Levie.[13] WordPress developer Automattic and Content Delivery Network providers MaxCDN and CloudFlare have become funding partners for an update to Google's SPDY version 3.1, slated for early 2014. [14]

Nginx uses an asynchronous event-driven approach to handling requests, instead of the Apache HTTP Server model that defaults to a threaded or process-oriented approach, where the Apache Mina Framework is required for asynchronous processing.[15] Nginx's modular event-driven architecture[16] can provide more predictable performance under high loads.[17]

Originally, nginx was developed to fill the needs of websites including Rambler, for which it was serving 500 million requests per day by September 2008.[18] According to Netcraft's February 2014 Web Server Survey,[19] nginx was found to be the third most widely used web server across all domains (15% of surveyed sites) and the second most widely used web server for all "active" sites (13.46% of surveyed sites). According to W3Techs, it was used by 21.5% of the top 1 million websites, 29% of the top 100,000 websites, and by 38.5% of the top 1,000 websites.[20] According to BuiltWith, it is used on 20.8% of the top 10,000 websites, and its growth within the top 10k, 100k and 1 million segments increased.[21] Wikipedia uses nginx as its SSL termination proxy.[22] As of OpenBSD release 5.2 (1 November 2012), nginx became part of the OpenBSD base system, providing an alternative to the system's fork of Apache 1.3, which it was intended to replace.[23]

HTTP Proxy and Web server features

Mail proxy features

Other features include upgrading executable and configuration without client connections loss,[35] and a module-based architecture.[36]
