Last month the Apache Software Foundation (ASF) celebrated its 10th anniversary. Apache is the underlying web server technology that powers most of the world’s web sites. According to Netcraft, 49.95% of web sites run on servers powered by Apache. The second closest web server technology belongs to Microsoft at 29.27%.
What is most surprising about those statistics is that Apache is free and open source software and ASF is a non-profit organization. ASF consists of 300 individual members and over 2,000 collaborators from all over the world.
Apache web server is a cross-platform software application that is customisable due to the nature of its license. It runs on Windows, Linux, BSD, Solaris, and many other operating systems.
