Ubuntu is a widely used desktop OS, which uses the Linux kernel, but its server edition is getting very popular too. The reason is that the OS is amazingly light and it'll run on almost any hardware without any issues, utilizing its resources to the max. Ubuntu is also pretty reliable and secure and all the Long-Term Support (LTS) versions are supported for at least five years, which guarantees that you should have a protected and dependable software environment on your hosting server at all times. Furthermore, Ubuntu has one of the biggest user communities on earth, so if you experience any difficulty or have any kind of question, you will find a number of resources online. One of the main benefits of this OS is that it comes with a large number of software packages that can be easily customized according to your needs and the requirements of the applications which you intend to run, not to mention that you will not have to pay any kind of license fees at any time. In comparison, other Operating Systems are paid and their code is not accessible, thus it cannot be changed.
