Ubuntu is a widespread desktop OS, which uses the Linux kernel, but its server edition is getting quite popular as well. The reason is that the operating system is amazingly light and it will run on almost any kind of 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 risk-free and stable software environment on your website hosting server all the time. Also, Ubuntu has one of the biggest user communities worldwide, so if you experience any issue or have any kind of question, you will find a number of resources online. One of the key advantages of this Operating System is the fact that it has thousands of software packages that can be easily adjusted according to your needs and the needs of the apps that you want to run, not to mention that you won't have to pay any license fees at any time. In comparison, other Operating Systems are paid and their program code isn't accessible, which means that it can't be changed.
