CentOS is an abbreviation for Community Enterprise OS. This is one of the top Linux releases for servers and it's recognized as one of the most reliable and safe Operating Systems available. CentOS is open-source software, so you will be able to personalize it in any way you see fit, adding and removing packages or updating the program code of any 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 overall price that you'll need 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 unique among various other Linux distributions is its huge developer community, that will help you find the reply to any question or problem you may have. What's even more, each version that's released officially is supported for 10 years, which is a lot longer than with any other OS. This means routine protection and stability updates which provides a dependable software setting for all of your web applications in the long run.
