Ubuntu is a widespread desktop OS, which uses the Linux kernel, but its server edition is getting quite popular as well. The reason is the fact that the OS is really light and it will function on almost any kind of hardware without issues, utilizing its resources to the maximum. Ubuntu is also really reliable and secure and all the Long-Term Support (LTS) versions are supported for at least five years, which warrants that you will have a risk-free and dependable software environment on your server all of the time. In addition, Ubuntu has one of the biggest user communities around the world, which means that if you experience any difficulty or have any question, you'll find plenty of resources on the web. Among the basic benefits of this OS is the fact that it comes with a great number of software packages that can be easily changed according to your needs as well as the requirements of the applications that you would like to run, not to mention that you will not have to pay any kind of license fees at any time. In contrast, other Operating Systems are paid and their code isn't accessible, which means that it can't be changed.
