CentOS is an abbreviation for Community Enterprise OS. This is one of the leading Linux distributions for servers and it is regarded as one of the most dependable and risk-free Operating Systems out there. CentOS is open-source software, so you're able to personalize it in any 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 kind of license fees, meaning that the total price that you will need to pay for a server running CentOS will be more affordable than the price for a server running some other OS. What makes CentOS stand out among other Linux distributions is its huge developer community, which will help you discover the answer to any kind of question or problem you have. Furthermore, each version which is released officially is supported for ten years, which is much longer than with any alternative operating system. What this means is regular safety and stability updates which will provide a great software setting for all your web apps in the long run.
