Ubuntu is also very reliable and secure and all the Long-Term Support (LTS) editions are supported for at least five years, which warrants that you should have a secure and dependable software environment on your website hosting server all the time. Furthermore, Ubuntu has one of the biggest user communities in the world, which means that if you experience any kind of problem or have any question, you will discover numerous resources online. Among the basic advantages of this OS is the fact that it contains a great number of software packages that can be freely adjusted according to your needs and / or the requirements of the applications that you need to run, not to mention that you won't have to pay any license fees at any time.
