CentOS is one of the preferred Operating Systems for website hosting servers. It's one of the countless Linux releases out there, yet what differentiates it from the others is the long-term support, which guarantees that you will always have a stable and secure OS. Every CentOS version that is released is supported for a decade, that is longer than with almost every other OS in existence. CentOS also has a much larger developer community than other distributions, therefore in the event you encounter any kind of problem or have any questions, you will be able to instantly find the details that you need. CentOS is considered to be among the best server Operating Systems, due to the fact that it's very stable and secure, which makes it very reliable even if you host private data. Because it is open-source, you are able to modify each and every 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, because you will not have to pay license fees of any type.
