While Linux is not widely used on desktops (making up about 3 percent of the overall desktop operating system market share in October 2017, according to NetMarketShare), it is extraordinarily strong on the web server side, where it enjoys a market share of more than 50 percent (W3Techs).

IT professionals invest considerable time learning about server computing for everything from installation, configuration, maintenance and virtualization to application support and so forth. This also means that many IT professionals are working with and around Linux operating systems daily, often alongside Windows and various UNIX OS brands as well.

The best of the Linux certifications vie for considerable mindshare among IT professionals and present an interesting mix of distribution (or brand) agnostic credentials alongside some pretty formidable vendor-specific credentials. There are multiple well-elaborated certification ladders available to those interested in learning, using and mastering the Linux operating system environment and all the many bells and whistles it supports.

The results of a job search we conducted on several popular job posting sites show which Linux certifications employers are looking for when hiring new employees. While results vary from day to day (and job board to job board), this recites those Linux-related certifications that employers were seeking.
