CentOS is short for Community Enterprise Operating System. This is one of the best Linux releases for servers and it's regarded as being one of the most reliable and secure Operating Systems available. 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 changing the program code of all of them. It is also free to distribute and use, so you will not need to pay any license fees, meaning that the overall price that you'll have to pay for a server making use of CentOS will be lower than the price for a server working with an alternative OS. What makes CentOS stand out among other Linux releases is its huge developer society, which will help you get the reply to any kind of question or problem you have. In addition, each version that is released officially is supported for 10 years, that is is much longer than with any alternative operating system. What this means is regular security and stability updates that will provide a great software setting for all of your web applications in the long run.
