CentOS is one of the most widely used Operating Systems for web hosting servers. It is one of the many Linux releases available, but what differentiates it from all of the rest is the long-term support, which ensures that you'll always have a reliable and secure OS. Each CentOS version that is released is supported for a decade, that is considerably longer than with almost every other OS out there. CentOS also has a much more numerous developer community than other distributions, therefore in the event you experience any problem or have some questions, you are able to promptly find the details that you need. CentOS is widely known as one of the best server Operating Systems, as it is very stable and secure, which makes it really reliable even when you host confidential data. Due to the fact that it is open-source, you're able to modify 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, since you will not have to pay license fees of any type.
