Ubuntu is also extremely reliable and secure and all the Long-Term Support (LTS) versions are supported for a minimum of five 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 largest user communities globally, which means that if you experience any issue or have any kind of question, you'll discover a number of resources on the web. One of the main benefits of this Operating System is that it comes with a great number of software packages that can be easily modified in accordance with your needs as well as the needs of the apps that you'd like to run, not to mention that you will not have to pay any license fees any time.
