Many operating system administrators and users ask questions about the best Enterprise Linux distribution. Therefore, to help you make an optimal choice, we have prepared a table comparing EuroLinux with other systems such as CentOS, RHEL®, Oracle® Linux, AlmaLinux or Rocky Linux.
Enterprise Linux distributions are a family of operating systems that are derived from the Red Hat® Enterprise Linux® source code. Thanks to their origin they provide not only proven security, reliability and identical functionality, but at the same time they can be used interchangeably. Also, their repositories (sources of system patches) can be used interchangeably and, if necessary, in an automated way to switch from one repository to another. The Enterprise Linux family includes, among others: RHEL®, EuroLinux, CentOS, Oracle® Linux, AlmaLinux, and Rocky Linux.
These systems, while functionally and technically the same, differ in such things as support, licensing, business strategy, or the opportunities a particular distribution opens up for community collaboration. In the table below we present a comparison of important features of the most popular Enterprise Linux distributions:
