CentOS is an abbreviation for Community Enterprise Operating System. This is one of the best Linux releases for servers and it is well known as being one of the most stable and protected Operating Systems on the market. CentOS is open-source software, which means that you are able to personalize it in whatever way you see fit, adding and removing packages or altering the program code of any of them. It's also free to distribute and use, so you won't need to pay any license fees, which means that the overall price that you will need to pay for a server making use of CentOS will be much lower as compared to the price for a server running an alternative OS. What makes CentOS stand out among other Linux releases is its huge developer community, which will help you find the reply to any question or problem you may have. What's even more, each version that is released officially is supported for a decade, that is is a lot longer than with any other operating system. This means ordinary safety and stability updates that provides a stable software environment for all your web apps in the long run.
