Debian is a Linux release, which is widely used for desktop computers, yet it's been gaining popularity as a server Operating System during the last couple of years as well. It is very dependable and risk-free, as fixes are released in just a few days after a problem is discovered. Debian has a huge support community, so when you have any questions or problems with the OS or with any of the 30,000+ packages it features, you will be able to contact the developers directly via electronic mail using special mailing lists and receive a response in just 15-20 min. The Debian community gives you the best level of support possible, since all of your questions will be handled by exactly the same people that made Debian in the first place, so they have an in-depth knowledge of how their own system functions. 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 additional software which you install without any restrictions, in order to optimize the software environment for your websites. Furthermore, Debian performs very well on any kind of hardware, because it is light and effective and does not need much memory.
