It is difficult to distinguish different Linux distributions by examining their TCP/IP characteristics, but inferences can be made from other clues, such as Server headers. This month alone, the number of Linux computers increased by more than 91,000 and again, this strong growth can largely be attributed to cloud hosting providers, where Linux-based instances are typically the cheapest and most commonly available. Web-facing operating systemsĪpache has been the most commonly installed web server for many years, but which underlying operating systems are used by the world's web facing computers?īy far the most commonly used operating system is Linux, which runs on more than two-thirds of all web-facing computers. A further 1,299 nginx-powered sites made their way into the top million this month, lifting nginx's share to 29.4%. However, Apache has also been experiencing a general decline since 2011, while nginx has continued to muscle its way in.

Today, 9.73% of the top million sites use Microsoft web server software (mostly IIS – Internet Information Services), while Apache leads with 38.9%. Microsoft's presence within the top million websites has also been steadily declining – in 2008, it had a 20% share, but this has since dwindled to less than 10%. Microsoft's active sites share has never exceeded Apache's, and ever since it peaked at 38% in early 2009, it has experienced a general decline. Discounting link farms, domain holding pages and other automatically generated content, Microsoft accounts for only 7.3% of all active sites, while Apache leads with 44.9%, and nginx follows with 20.7%. While more than half of the websites in the survey are using Microsoft web server software, relatively few of these are active sites. Meanwhile, Apache remains far ahead in the lead with 2.88 million web-facing computers giving it a 42.3% share of the market. This puts it within 20,000 computers of Microsoft's 22.5% share, giving nginx a realistic chance of taking second place by next month. Nginx has dominated this month's computer growth once again, with an additional 49,900 computers taking its market share up to 22.2%. The top three cloud hosting providers-Amazon, Alibaba and DigitalOcean-now account for nearly 22% of all web-facing computers, as well as more than a third of this month's net computer growth. This is the largest number of web-facing computers in history, and cloud computing has helped fuel this growth considerably. In the September 2017 survey we received responses from 1,805,060,730 sites and 6,798,101 web-facing computers, reflecting a gain of 4.49 million sites and 84,800 computers.
