Every CentOS version that is released is supported for 10 years, that's a lot longer than with almost every other OS in existence. CentOS also has a much more numerous developer community than other distributions, therefore in case you encounter any kind of problem or have some questions, you'll be able to promptly discover the data that you need. CentOS is considered to be among the best server Operating Systems, due to the fact that it's very stable and protected, which makes it very reliable even if you host confidential data.
