CentOS is an abbreviation for Community Enterprise Operating System. This is one of the top Linux distributions for servers and it is recognized as one of the most reliable and risk-free Operating Systems out there. 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 altering the code of any of them. It's also free to distribute and use, so you won't have to pay any license fees, which means that the total price that you'll need to pay for a server running CentOS will be lower as compared to the price for a server working with another OS. What makes CentOS stand out among other Linux releases is its huge developer community, that will help you find the reply to any kind of question or problem you may have. What's even more, each version which is released officially is supported for a decade, which is longer than with any alternative operating system. This means regular safety and stability updates which will provide a dependable software setting for your web applications in the long run.
