CentOS is amongst the most widely used Linux-based server Operating Systems today. It is employed by countless web hosting providers, because it's very stable, reliable and secure, not to mention that it can be customized freely, because it's an open-source Operating System. CentOS is used for production servers, as it's also very fast and takes minimal system resources. In addition, you'll be able to set up and run any web app, provided that it can operate on a Linux machine. If you use a CentOS-powered server, you're able to edit any part of the Operating System according to your specifications. The fact that CentOS is provided for free means that you will have to pay just for your server, but not for any kind of license fees, which will decrease your overall expenses. A large team of developers and users is behind CentOS, so that in case you ever encounter any problems, or you are simply unsure how to perform a particular task, you can find a solution right away. An important advantage of the OS is also the fact that every release is officially supported and updated for a minimum of 10 years, so you'll always have a safe and dependable software environment.
