Linux is a Unix-like and mostly POSIX-compliant computer operating system assembled under the model of free and open source software development and distribution. How much you need to know about Linux, depends on how involved you need to be in fine tuning your website. Simply it is what makes your website go, kind of like the engine in your car.

Some reasons you might consider choosing Linux as the web server operating system are:

  • Low cost- If necessary, with considerable effort and skill, Linux can be downloaded for free and installed on a re-purposed (used) computer and run from your garage.
  • No vender lock-in. There is no one vendor that has all of the market share. If one version is not working out okay a switch can be made without too much trouble.
