CentOS

CentOS is short for Community Enterprise OS. This is one of the best Linux releases for servers and it is regarded as being one of the most stable and secure Operating Systems available. 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 updating the program code of all of them. It is also free to distribute and use, so you won't need to pay any license fees, meaning that the overall price that you'll have to pay for a server running CentOS will be cheaper 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, that will help you get the reply to any question or problem you have. Furthermore, each version which is released officially is supported for 10 years, that's is a lot longer than with any alternative operating system.
