CentOS is among the most widely used Linux-based server Operating Systems to choose from. It is used by many hosting service providers, as it is very stable, secure and reliable, not to mention that it can be customized freely, because it is an open-source Operating System. CentOS is used for production servers, because it's also very quick and takes minimal resources. What's more, you're able to install and run any web app, as long as it can run on a Linux computer system. When you use a CentOS-powered server, you are able to edit any part of the Operating System according to your preferences. The fact that CentOS is provided for free means that you will have to pay just for your server, and not for any sort of license fees, which will decrease your overall expenses. A large community of developers and users is behind CentOS, so that if you ever encounter any kind of problems, or you are simply not sure how to perform a particular task, you can discover a solution in no time. An important advantage of the OS is also the fact that every release is officially supported and updated for a minimum of ten years, so that you will always have a secure and dependable software environment.
