Debian is a Linux distribution, which is widespread for desktop machines, yet it's been becoming more popular as a server Operating System over the last couple of years too. It is very stable and secure, since fixes are released in a few days after an issue is discovered. Debian has a large support community, so if you have any questions or issues with the OS or with any of the 30,000+ packages it includes, you will be able to contact the developers directly via electronic mail using special mailing lists and receive a reply within 15-20 min. The Debian community supplies the top level of support possible, since all your questions will be handled by the very same people who made Debian in the first place, so they have an in-depth knowledge of how their own system functions. Since the Operating System is 100% free to use and distribute, no license charges will be added to your website hosting fees and you will be able to change the program code files and any other software which you install without any restrictions, in order to optimize the software environment for your web sites. Furthermore, Debian performs very well on any hardware, because it is light and effective and does not need much memory.
