CentOS is short for Community Enterprise Operating System. This is one of the best Linux releases for servers and it is regarded as being one of the most stable and secure Operating Systems available. CentOS is open-source software, which means that you're able to personalize it in any way you see fit, adding and removing packages or altering the program code of all of them. It's also free to distribute and use, so you will not have to pay any kind of license fees, which means that the total price that you'll need to pay for a server running CentOS will be more affordable than the price for a server working with an alternative OS. What makes CentOS unique among various other Linux releases is its huge developer society, that will help you find the reply to any kind of question or problem you might have. What's more, each version that's released officially is supported for a decade, which is much longer than with any other OS. What this means is ordinary safety and stability updates that will provide a stable software environment for all your web applications in the long run.
