CentOS is one of the most widely used Operating Systems for hosting servers. It is one of the countless Linux distributions in existence, yet what distinguishes it from all the others is its long-term support, which ensures that you'll always have a reliable and protected Operating System. Each CentOS version that is released is supported for ten years, that is longer than with any other OS in existence. CentOS also has a much larger developer community than other distributions, therefore in case you encounter any problem or have some questions, you can instantly discover the details which you need. CentOS is widely known as among the best server Operating Systems, because it is very stable and secure, which makes it really reliable even if you host sensitive data. Because it is open-source, you'll be able to modify each and every part of it and personalize it according to your needs, not to mention that the total cost for a CentOS-based server will be lower, since you will not have to pay license fees of any type.
