Ubuntu is also pretty reliable and secure and all Long-Term Support (LTS) releases are supported for a minimum of five years, which warrants that you should have a risk-free and stable software environment on your hosting server all of the time. Also, Ubuntu has one of the largest user communities on the planet, so if you experience any kind of problem or have any question, you'll find a number of resources online. Among the major benefits of this OS is that it features numerous software packages which can be freely changed in accordance with your needs as well as the needs of the applications which you want to run, not to mention that you will not have to pay any license fees any time.
