Ubuntu is a well-liked desktop Operating System, which uses the Linux kernel, but its server edition is getting very popular too. The main reason is that the OS is very light and it can run on almost any hardware without any issues, utilizing its resources to the maximum. Ubuntu is also pretty reliable and secure and all Long-Term Support (LTS) versions are supported for a minimum of 5 years, which warrants that you will have a protected and stable software environment on your website hosting server at all times. Furthermore, Ubuntu has one of the largest user communities on the planet, so if you experience any issue or have any question, you'll discover plenty of resources on the net. One of the main benefits of this OS is the fact that it has a large number of software packages that can be easily changed according to your needs and the needs of the apps which you need to run, not to mention that you won't have to pay any license fees any time. In comparison, other OS's are paid and their program code isn't accessible, therefore it cannot be changed.
