Ubuntu is a popular desktop Operating System, which uses the Linux kernel, and its server release is getting quite popular as well. The main reason is the fact that the OS is very light and it can run on almost any hardware without any issues, utilizing its resources to the max. Ubuntu is also pretty reliable and secure and all of the Long-Term Support (LTS) releases are supported for a minimum of five years, which guarantees that you should have a secure and stable software environment on your hosting server all of the time. In addition, Ubuntu has one of the biggest user communities on earth, which means that if you experience any kind of problem or have any kind of question, you'll find a number of resources on the Internet. Among the main benefits of this Operating System is that it includes a great number of software packages which can be easily customized according to your needs as well as the requirements of the apps that you need to run, not to mention that you will not have to pay any kind of license fees any time. In comparison, other Operating Systems are paid and their program code is not accessible, thus it cannot be changed.
