Ubuntu is a well-liked desktop OS, that uses the Linux kernel, and its server edition is getting very popular too. The main reason is the fact that the operating system is extremely light and it'll run on almost any hardware with no issues, utilizing its resources to the max. Ubuntu is also pretty reliable and secure and all the Long-Term Support (LTS) editions are supported for at least 5 years, which guarantees that you will have a protected and dependable software environment on your hosting server at all times. In addition, Ubuntu has one of the biggest user communities around the world, which means that if you experience any problem or have any question, you will discover a number of resources on the net. One of the key advantages of this OS is that it contains thousands of software packages which can be easily adjusted according to your needs and the requirements of the applications that you wish to run, not to mention that you will not have to pay any license fees at all. In contrast, other OS's are paid and their program code isn't accessible, thus it cannot be changed.
