Debian is a Linux release, that is widely used for desktop computers, however it's been gaining in popularity as a server OS during the last few years too. It is really stable and secure, due to the fact that fixes are released within a few days after an issue is discovered. Debian has a huge support community, so when you have any questions or issues with the OS or with some of the 30,000+ packages it includes, you will be able to contact the developers straight away via email using special e-mail lists and receive a response in just 15-20 minutes. The Debian community supplies the top level of support possible, since all your questions will be handled by the very same people that created Debian in the first place, so they have an exhaustive knowledge of how their own system operates. Because the Operating System is 100% free to use and distribute, no license charges will be included with your hosting fees and you will be able to change the code files and any other software that you install without any restrictions, to optimize the software environment for your Internet sites. In addition, Debian performs really well on any kind of hardware, as it's light and fast and doesn't need much memory.
