Apache HTTP Server, colloquially called Apache (/əˈpætʃiː/ ə-PA-chee), is free and open-source cross-platform web server software, released under the terms of Apache License 2.0. Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation - wikipedia 
Apache HTTP Server is cross-platform, meaning that it is built for Unix-like systems (e.g., macOS, Linux and FreeBSD) as well as Windows. However, As of 1 June 2017, 92.26% of all Apache HTTPS Server copies ran on Linux distributions. Version 2.0 improved support for non-Unix, e.g. Windows and OS/2 (and eComStation). Old versions of Apache were ported to run on e.g. OpenVMS, and NetWare.
Originally based on the NCSA HTTPd server, development of Apache began in early 1995 after work on the NCSA code stalled. Apache played a key role in the initial growth of the World Wide Web, quickly overtaking NCSA HTTPd as the dominant HTTP server, and has remained most popular since April 1996. In 2009, it became the first web server software to serve more than 100 million websites.
As of July 2016, Apache remained the most widely used web server software, estimated to serve 46% of all active websites and 43% of the top million websites.
