"Established in 1999, the all-volunteer Apache Software Foundation oversees more than 350 leading Open Source projects, including Apache HTTP Server --the world's most popular Web server software."
How long will that last claim remain true? We can sum up the state of affairs from four well-respected web server popularity reports from three sources; https://news.netcraft.com/archives/2018/03/27/march-2018-web-server-survey.html (Based on 214M hostnames / 7M IP's) https://secure1.securityspace.com/s_survey/data/201803/index.html (Based on 63M hostnames) https://secure1.securityspace.com/s_survey/data/man.201803/httpbyip.html (Based on 5M IP's) https://w3techs.com/technologies/overview/web_server/all (Based on Alexa-ranked top ~10M primary domains) Notably, we now hold the minority-majority position across the "web server" space, discounting the fact that "unknown/other" would probably still land us at 50% using really simple stats, for some few more months. Still, there is an unarguable downward trend of adoption and relevance of Apache httpd. Depending on which survey you examine, either IIS or ngnix has caught up rapidly; the disagreement between surveys is often laughable. While IP's themselves might make for a better mapping, these are equally 'virtual' and don't represent machines either. Mass hosting, by name or number, is easily observed in these reports with huge swings from month to month. Reports which don't feature as much swing have apparently factored out much of the duplicated noise/domain camping. As as been restated over and over, http:// is effectively DOA, long live https:// (h2, etc). Brings us to the point that we have not been the most popular HTTP/TLS server for over two years, and you can surmise what this will do over time to the numbers offered above; https://secure1.securityspace.com/s_survey/sdata/201803/index.html https://secure1.securityspace.com/s_survey/sdata/201803/servers.html Many will always carry a deep fondness or appreciation for Apache httpd; how much traffic it actually carries in future years is another question entirely, and has everything to do with the questions we should have solved some time ago, and aught to solve now. Better late than never.
