Ubuntu is a preferred desktop Operating System, which uses the Linux kernel, but its server release is getting very popular too. The main reason is the fact that the OS is really light and it will function on almost any kind of hardware without issues, utilizing its resources to the fullest. Ubuntu is also really reliable and secure and all the Long-Term Support (LTS) editions are supported for a minimum of five years, which warrants that you will have a secure and dependable software environment on your web hosting server all the time. Furthermore, Ubuntu has one of the biggest user communities worldwide, so if you experience any problem or have any question, you will discover numerous resources online. One of the major benefits of this Operating System is the fact that it features numerous software packages that can be easily modified according to your needs and the needs of the apps that you wish to run, not to mention that you won't have to pay any kind of license fees at any time. In comparison, other OS's are paid and their program code is not accessible, thus it cannot be changed.
