CentOS is an abbreviation for Community Enterprise Operating System. This is one of the best Linux releases for servers and it's regarded as one of the most stable and risk-free Operating Systems on the market. CentOS is open-source software, which means that you are able to customize it in whatever way you see fit, adding and removing packages or changing the code of any of them. It is also free to distribute and use, so you will not need to pay any kind of license fees, meaning that the overall price that you'll have to pay for a server making use of CentOS will be more affordable as compared to the price for a server running an alternative OS. What makes CentOS unique among various other Linux distributions is its huge developer society, which will help you get the answer to any kind of question or problem you have. What's more, each version that is released officially is supported for ten years, that's is much longer than with any other OS. This means ordinary security and stability updates which provides a stable software setting for all your web applications in the long run.
