CentOS is short for Community Enterprise Operating System. This is one of the best Linux releases for servers and it's well known as one of the most stable and safe Operating Systems on the market. CentOS is open-source software, so you will be able to personalize it in any way you see fit, adding and removing packages or changing the program code of any of them. It is also free to distribute and use, so you won't have to pay any kind of license fees, which means that the overall price that you will have to pay for a server running CentOS will be much lower than the price for a server working with another OS. What makes CentOS unique among other Linux distributions is its huge developer community, that will help you find the reply to any question or problem you have. Furthermore, each version that is released officially is supported for 10 years, which is much longer than with any alternative operating system. What this means is routine safety and stability updates that provides a dependable software environment for all of your web applications in the long run.
