Ubuntu is a widespread desktop Operating System, that uses the Linux kernel, but its server release is getting really popular as well. The main reason is that the operating system is very light and it can function on almost any kind of hardware without any issues, utilizing its resources to the fullest. Ubuntu is also extremely reliable and secure and all Long-Term Support (LTS) versions are supported for at least five years, which warrants that you should have a protected and dependable software environment on your web hosting server at all times. In addition, Ubuntu has one of the largest user communities worldwide, so if you experience any difficulty or have any kind of question, you will find plenty of resources on the net. Among the basic benefits of this OS is that it features tens of thousands of software packages which can be easily adjusted according to your needs and the requirements of the applications that you would like to run, not to mention that you will not have to pay any license fees any time. In contrast, other OS's are paid and their code isn't accessible, thus it cannot be changed.
