CentOS is one of the most widely used Operating Systems for website hosting servers. It is one of the numerous Linux releases available, yet what distinguishes it from all of the others is its long-term support, which ensures that you will always have a stable and safe OS. Each CentOS version that is released is supported for ten years, that's longer than with any other OS on the market. CentOS also has a much more numerous developer community than other distributions, so if you experience any problem or have some questions, you'll be able to rapidly get the details which you need. CentOS is widely known as one of the best server Operating Systems, because it is very stable and protected, which makes it very reliable even when you host sensitive information. Due to the fact that it is open-source, you're able to modify any part of it and customize it according to your requirements, not to mention that the total cost for a CentOS-based server will be lower, as you will not have to pay license fees of any sort.
