CentOS is one of the preferred Operating Systems for web hosting servers. It's one of the countless Linux distributions in existence, yet what distinguishes it from all the rest is its long-term support, which guarantees that you'll always have a reliable and secure OS. Each CentOS version that is released is supported for ten years, which is longer than with almost every other OS out there. CentOS also has a much larger developer community than other distributions, therefore in case you encounter any problem or have some questions, you'll be able to promptly discover the information 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. Because it is open-source, you are able to modify each and every part of it and customize it according to your needs, not to mention that the total cost for a CentOS-based server will be lower, as you won't have to pay license fees of any sort.
