CentOS is short for Community Enterprise Operating System. This is one of the best Linux releases for servers and it is regarded as one of the most dependable and secure Operating Systems on the market. CentOS is open-source software, so you are able to personalize it in whatever way you see fit, adding and removing packages or modifying the program code of any of them. It is also free to distribute and use, so you will not have to pay any kind of license fees, meaning that the total price that you'll have to pay for a server running CentOS will be much lower as compared to the price for a server running another OS. What makes CentOS stand out among various other Linux distributions is its huge developer society, that will help you discover the answer to any kind of question or problem you might have. Furthermore, each version that's released officially is supported for ten years, that is is longer than with any other OS. This means frequent safety and stability updates that provides a great software setting for your web apps in the long run.
