CentOS is short for Community Enterprise Operating System. This is one of the leading Linux releases for servers and it is regarded as one of the most dependable and safe Operating Systems on the market. CentOS is open-source software, which means that you're able to customize it in any way you see fit, adding and removing packages or updating the code of any of them. It is also free to distribute and use, so you will not need to pay any kind of license fees, meaning that the total price that you'll have to pay for a server running CentOS will be more affordable than the price for a server working with some other OS. What makes CentOS stand out among various other Linux distributions is its huge developer society, which will help you discover the answer to any question or problem you might have. What's even more, each version that's released officially is supported for 10 years, that's is much longer than with any alternative OS.
