Debian is a well-known Linux release, that is used mainly on desktop computers, however lots of people have begun using it lately as a web server Operating System as well, because of the stability and security it offers. The latter is a result of the fact that Debian is developed and supported by thousands of qualified volunteers around the globe, so that any patch that's required to fix a particular issue is released in a few days. The very same community can also help with any question or issue which a user may ever have, because they can be contacted via e-mail using e-mail lists and a qualified response will be sent in no more than 15-20 minutes. The advantage here is that all your queries will be answered by the same people who have designed the Operating System itself and they have an in-depth knowledge of how it functions. As Debian is absolutely free, you won't need to pay any license fees to use it and you will be able to personalize it as much as you want or need. This is valid for both the Operating System and the 30.000+ software packages which are readily available for it.
