The biggest players in the web server business, Apache and IIS, have had the field to themselves for a long time. Now, however, they have to contend with a few seriously capable upstarts, the most prominent of which is Nginx (pronounced ‘engine-x’). This young turk was first developed in 2002 and boasts a growing, dedicated following among many webmasters. Nginx’s popularity is mainly due to being open-source and having the desirable combination of high performance and low resource consumption. It is important to note that Nginx is most often compared to Apache due to its similar open-source philosophy.
