CentOS is an abbreviation for Community Enterprise OS. This is one of the top Linux distributions for servers and it is well known as being one of the most reliable and risk-free Operating Systems on the market. CentOS is open-source software, which means that you'll be able to personalize it in whatever way you see fit, adding and removing packages or altering the program code of any of them. It's also free to distribute and use, so you will not need to pay any license fees, meaning that the total price that you will have to pay for a server making use of CentOS will be cheaper as compared to the price for a server running some other OS. What makes CentOS stand out among various other Linux releases is its huge developer society, which will help you find the reply to any question or problem you might have. What's even more, each version that's released officially is supported for a decade, that is is longer than with any alternative operating system. This means regular protection and stability updates which provides a stable software setting for your web applications in the long run.
