It’s hard to pin down exactly how popular Linux is on the web, but according to a study by W3Techs, Unix and Unix-like operating systems power about 67 percent of all web servers. At least half of those run Linux—and probably the vast majority.

What percentage of servers run Linux?

In 2019, the Windows operating system was used on 72.1 percent of servers worldwide, whilst the Linux operating system accounted for 13.6 percent of servers.

Why most servers are Linux?

Linux servers are widely used today and considered amongst the most popular due to their stability, security, and flexibility, which outstrip standard Windows servers. Another major benefit of using Linux over closed-source software like Windows is that the former is fully open-source.
