Ubuntu is a well-liked desktop OS, which uses the Linux kernel, and its server version is getting very popular too. The reason is the fact that the operating system is amazingly light and it can run on almost any hardware with no issues, utilizing its resources to the fullest. Ubuntu is also really reliable and secure and all of the Long-Term Support (LTS) editions are supported for at least 5 years, which guarantees that you will have a secure and stable software environment on your web hosting server all of the time. In addition, Ubuntu has one of the largest user communities on earth, which means that if you experience any problem or have any question, you will discover plenty of resources on the web. One of the major advantages of this OS is the fact that it features numerous software packages that can be freely modified in accordance with your needs as well as the requirements of the apps that you'd like to run, not to mention that you will not have to pay any license fees any time. In contrast, other Operating Systems are paid and their program code isn't accessible, which means that it can't be changed.
