Debian is a Linux distribution, that is widely used for desktop computers, but it has been gaining in popularity as a server Operating System over the last few years too. It's very dependable and risk-free, due to the fact that fixes are released in a few days after a problem is discovered. Debian has a large support community, so if you have any kind of questions or troubles with the OS or with any of the 30,000+ packages it is equipped with, you are able to contact the developers directly through electronic mail using special e-mail lists and receive a reply in 15-20 minutes. The Debian community gives you the top level of support possible, because your questions will be handled by exactly the same people who made Debian in the first place, so they have an exhaustive knowledge of how their own system functions. Because the Operating System is absolutely free to use and distribute, no license costs will be included with your hosting fees and you can modify the code files and any additional software which you install without restrictions, so as to optimize the software environment for your Internet sites. Furthermore, Debian performs really well on any hardware, as it is light and efficient and does not need much memory.
