CentOS is amongst the most preferred Linux-based server Operating Systems on the market. It's used by a number of web hosting providers, as it's very stable, reliable and secure, not to mention that it is freely customizable, since it is an open-source Operating System. CentOS is used for production servers, because it is also very fast and takes minimal resources. On top of that, you are able to set up and run any web application, as long as it can run on a Linux computer system. When you use a CentOS-powered server, you will be able to edit any part of the Operating System according to your needs. The fact that CentOS is free also means that you will need to pay for your server, but not for any kind of license fees, which will cut down your overall expenses. A large team of developers and users stands behind CentOS, so in case you ever experience any problems, or you are simply not sure how to perform a certain task, you will be able to find a solution right away. An important advantage of the OS is also the fact that each and every version is officially supported and updated for no less than 10 years, so that you'll always have a safe and dependable software environment.
