CentOS is an abbreviation for Community Enterprise Operating System. This is one of the leading Linux releases for servers and it's regarded as being one of the most dependable and risk-free Operating Systems out there. CentOS is open-source software, which means that you're able to customize it in any way you see fit, adding and removing packages or altering the program code of all of them. It is also free to distribute and use, so you will not have to pay any license fees, which means that the overall price that you'll need to pay for a server running CentOS will be much lower than the price for a server working with an alternative OS. What makes CentOS stand out among various other Linux releases is its huge developer community, that will help you discover the reply to any question or problem you may have. Furthermore, each version that is released officially is supported for a decade, which is a lot longer than with any other operating system. This means regular safety and stability updates that provides a reliable software setting for all your web applications in the long run.
