CentOS is among the most widely used Linux-based server Operating Systems on the market. It's used by countless website hosting service providers, since it's very stable, reliable and secure, not to mention that it is freely customizable, because it's an open-source OS. CentOS is used for production servers, as it is also very fast and takes negligible system resources. In addition, you can set up and run any kind of web application, as long as it can operate on a Linux device. When you use a CentOS-powered server, you will be able to adjust any part of the Operating System according to your preferences. The fact that CentOS is absolutely free means that you will need to pay for your server, but not for any sort of license fees, which will reduce your overall expenses. A vast group of developers and users stands behind CentOS, so that if you ever experience any problems, or you are simply unsure how to perform a specific task, you can find a solution right away. A significant benefit of the OS is also the fact that each release is officially supported and updated for no less than 10 years, so that you'll always have a secure and reliable software environment.
