Top by OS

Top by OS lists the most popular server-side Operating Systems by number of websites (domains) they serve and provides the OS usage share in percent. Server-side OS is the software the server operating a website uses to manage it. Contrary to the personal computers sphere, where Microsoft Windows dominates, the more complex and demanding server world adheres to so-called *nix systems such as Linux and Unix.
