CentOS is one of the preferred Operating Systems for website hosting servers. It's one of the countless Linux releases in existence, but what differentiates it from the rest is the long-term support, which guarantees that you will always have a reliable and protected OS. Each CentOS version that is released is supported for 10 years, that is considerably longer than with another OS available on the market. CentOS also has a much more numerous developer community than other distributions, so if you experience any problem or have any questions, you will be able to rapidly find the information that you need. CentOS is considered to be one of the best server Operating Systems, since it's very stable and secure, that makes it very reliable even if you host confidential data. Due to the fact that 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, as you won't have to pay license fees of any sort.
