CentOS is an abbreviation for Community Enterprise Operating System. This is one of the top Linux releases for servers and it's well known as one of the most reliable and secure Operating Systems on the market. CentOS is open-source software, which means that you are able to customize it in any way you see fit, adding and removing packages or updating the code of any of them. It's also free to distribute and use, so you will not have to pay any kind of license fees, which means that the overall price that you will need to pay for a server running CentOS will be more affordable than the price for a server working with some other OS. What makes CentOS stand out among various other Linux releases is its huge developer community, that will help you find the answer to any kind of question or problem you have. What's even more, each version which is released officially is supported for a decade, that is is much longer than with any other operating system. This means regular safety and stability updates which will provide a dependable software setting for your web applications in the long run.
