CentOS is an abbreviation for Community Enterprise Operating System. This is one of the top Linux distributions for servers and it's recognized as one of the most dependable and secure Operating Systems out there. 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 code of any of them. It's also free to distribute and use, so you will not need to pay any license fees, which means 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 another OS. What makes CentOS stand out among other Linux releases is its huge developer community, that will help you get the answer to any question or problem you might have. Furthermore, each version that is released officially is supported for a decade, that's is much longer than with any alternative operating system. What this means is ordinary security and stability updates that provides a stable software setting for your web apps in the long run.
