Debian is a Linux release, that is preffered for desktop machines, but it has been gaining popularity as a server Operating System during the last couple of years too. It is very dependable and protected, due to the fact that fixes are released in just a few days after an issue is discovered. Debian has a huge support community, so if you have any questions or problems with the OS or with some of the 30,000+ packages it is equipped with, you can contact the developers without delay through electronic mail using special mailing lists and receive a reply in 15-20 min. The Debian community supplies the best level of support possible, as your questions will be handled by the same people that built Debian in the first place, so they have a detailed knowledge of how their system operates. Because the Operating System is absolutely free to use and distribute, no license costs will be added to your website hosting fees and you will be able to customize the program code files and any other software that you install without any restrictions, in order to optimize the software environment for your sites. In addition, Debian performs really well on any kind of hardware, as it is light and effective and doesn't require much memory.
