Web Server Statistics

 

A web server consists of several components – the operating system (e.g. Linux), the web server (e.g. Apache) and the programming language (e.g. PHP). There are a variety of combinations of these that occur on websites across the web. We analyzed the top four million domain names and the technologies that they use and in this post, we will summarize the data with charts. The most common configuration of a website is Linux/Apache/MySQL/PHP which is also called LAMP.

Operating System Market Share

Operating System Market ShareAs the above bar chart shows, most websites just say Linux (or Unix) instead of a specific flavor of Linux. The following table summarizes this data:

Logo Operating System Percentage Market Share
Linux Linux 46.3%
CentOS CentOS 16.6%
RedHat RedHat 10.9%
Ubuntu Ubuntu 9%
Debian Debian 7.67%
Fedora Fedora 3.51%
FreeBSD FreeBSD 2.06%
OVH OVH 1.64%
Windows Win32 1.27%
SUSE SUSE 1.05%

Note that except FreeBSD and Win32, all are flavors of Linux. Among the types of Linux, CentOS is the most popular one, followed by RedHat, Ubuntu, Debian, Fedora, and SUSE.

 Web Server Market Share

Web Servers Market ShareApache and Microsoft IIS are the leading web servers followed by Nginx.

All of these servers are very scalable and are used by several major companies.

  • YouTube, Wikipedia and eBay use Apache.
  • Pinterest, WordPress and About.com use Nginx.
  • IIS is used by several Microsoft websites like Microsoft.com, Bing and is also used by Go.com.

Programming Languages Market Share

Programming Languages Market SharePHP is the most popular programming language followed by Microsoft’s Active Server Pages (ASP). Java (or JSP or Servlets) is used by 0.4% of websites. Other programming languages that a small fraction of websites use are Perl, Python, C++, and Ruby.
