CentOS is one of the most widely used Operating Systems for website hosting servers. It is one of the many Linux releases available, however what distinguishes it from all the others is the long-term support, which ensures that you will always have a stable and safe Operating System. Every CentOS version that is released is supported for ten years, that's much longer than with any other OS available on the market. CentOS also has a much larger developer community than other distributions, therefore in case you experience any kind of problem or have any questions, you can quickly discover the data which you need. CentOS is regarded as one of the best server Operating Systems, because it is very stable and protected, that makes it really reliable even when you host private information. Due to the fact that it is open-source, you are able to modify any part of it and personalize it according to your needs, not to mention that the overall cost for a CentOS-based server will be lower, since you won't need to pay license fees of any sort.
