Ubuntu is a well-liked desktop OS, which uses the Linux kernel, but its server version is getting very popular too. The main reason is that the operating system is really light and it can function on almost any hardware without issues, utilizing its resources to the max. Ubuntu is also very reliable and secure and all of the Long-Term Support (LTS) versions are supported for at least five years, which guarantees that you should have a risk-free and dependable software environment on your hosting server all of the time. Also, Ubuntu has one of the biggest user communities on earth, which means that if you experience any kind of problem or have any question, you will discover plenty of resources on the net. One of the key advantages of this OS is the fact that it features thousands of software packages which can be freely customized in accordance with your needs and / or the requirements of the applications that you'd like to run, not to mention that you will not have to pay any kind of license fees at all. In contrast, other Operating Systems are paid and their program code isn't accessible, which means that it can't be changed.
