Debian is a Linux distribution, that's widespread for desktop computers, yet it's been gaining popularity as a server Operating System over the last couple of years as well. It's really dependable and risk-free, since fixes are released within a couple of days after a problem is discovered. Debian has a vast support community, so when you have any questions or problems with the OS or with some of the 30,000+ packages it includes, you're able to contact the developers immediately through electronic mail using special mailing lists and receive a response within 15-20 minutes. The Debian community supplies the best level of support possible, because all of 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 works. As the Operating System is free to use and distribute, no license costs will be included with your web hosting fees and you will be able to modify the code files and any additional software which you install with no restrictions, to optimize the software environment for your web sites. What's more, Debian performs very well on any hardware, as it is light and efficient and does not require a lot of memory.
