CentOS is short for Community Enterprise Operating System. This is one of the best Linux distributions for servers and it is regarded as being one of the most stable and secure Operating Systems out there. CentOS is open-source software, so you're able to customize it in whatever 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 license fees, which means that the total price that you will need to pay for a server running CentOS will be cheaper as compared to the price for a server working with another OS. What makes CentOS stand out among various other Linux distributions is its huge developer community, that will help you discover the reply to any kind of question or problem you have. In addition, each version that's released officially is supported for ten years, that's is a lot longer than with any other operating system. This means frequent protection and stability updates that provides a reliable software setting for all your web apps in the long run.
