Unlike other server programs, Nginx does not rely on streams (threads) to process the query (request). Instead, Nginx uses event-driven architecture (event-driven) asynchronous (asynchronous) and scalability. Even if you do not need to handle thousands of concurrent queries, then you should still use Nginx by high performance and low memory requirements of Nginx than Apache. Nginx can be used on VPS lowest configuration (as low vps package of digitalocean and vultr) until a huge system like cloud server with multiple clusters.

Currently (June 6/2014), Nginx has 14.6% market share (approximately 142 million web pages) program web servers worldwide (according to Netcraft statistics) and still have a high growth rate. Nginx is currently being used by the web service query with extremely high quality as Netflix, Hulu, Pinterest, CloudFlare, Airbnb, WordPress.com, GitHub, SoundCloud, Zynga, Eventbrite, Zappos, Media Temple, Heroku, RightScale, Engine Yard, MaxCDN, Yandex, Mail.Ru, Vkontakte, Rambler …
