CentOS is one of the preferred Operating Systems for web hosting servers. It's one of the many Linux releases out there, yet what differentiates it from all of the others is its long-term support, which ensures that you will always have a reliable and protected OS. Each CentOS version that is released is supported for ten years, that is a lot longer than with any other OS available. CentOS also has a much larger developer community than other distributions, therefore if you encounter any problem or have some questions, you'll be able to promptly find the details that you need. CentOS is considered to be among the best server Operating Systems, as it's very stable and secure, which makes it very reliable even if you host confidential information. Since it is open-source, you're able to modify each and every part of it and customize it according to your needs, not to mention that the overall cost for a CentOS-based server will be lower, because you will not need to pay license fees of any type.
