How does Red Hat Linux 8 compare with other Linux distributions?
Red Hat Linux 8 is one of the many Linux distributions available in the market. Each distribution has its own strengths, weaknesses, and target audiences. Here are some of the factors that distinguish Red Hat Linux 8 from other Linux distributions:
Enterprise vs. community distros
Red Hat Linux 8 is an enterprise Linux distribution that is designed for business and production environments. It offers features such as stability, security, support, compatibility, and scalability that are essential for enterprise customers. It also requires a subscription fee that covers the cost of these features and services. Community Linux distributions are designed for personal and hobbyist use. They offer features such as flexibility, customization, innovation, and diversity that are appealing for individual users. They also do not require any subscription fee and are supported by volunteers and donations.
Debian vs. Red Hat family
Red Hat Linux 8 belongs to the Red Hat family of Linux distributions that are based on Fedora and use .rpm packages and dnf as their package manager. Other members of this family include CentOS, Rocky Linux, AlmaLinux, Oracle Linux, Scientific Linux, and Amazon Linux. Debian is another major family of Linux distributions that are based on Debian and use .deb packages and apt as their package manager. Other members of this family include Ubuntu, Mint, Debian, Kali Linux, and Pop!_OS. The main differences between the Debian and Red Hat families are the package formats, the package managers, the release cycles, and the support models. Generally speaking, Debian-based distros are more user-friendly, more up-to-date, and more diverse, while Red Hat-based distros are more enterprise-oriented, more stable, and more consistent.
Fedora vs. CentOS vs. Rocky Linux
Fedora, CentOS, and Rocky Linux are three of the most popular Linux distributions that are derived from Red Hat Linux 8. They have different goals and use cases, but they share some common features and benefits. Fedora is the upstream source of Red Hat Linux 8 and the testing ground for new technologies and innovations. It is a community-driven project that releases new versions every six months with cutting-edge software and features. It is suitable for developers, testers, and enthusiasts who want to experience the latest and greatest in Linux. CentOS is a downstream clone of Red Hat Linux 8 that provides a free and open source alternative to RHEL. It is a community-supported project that releases new versions after RHEL with the same software and features. It is suitable for users who want to use RHEL without paying for a subscription or who need a stable and reliable platform for their applications. Rocky Linux is a new downstream clone of Red Hat Linux 8 that aims to replace CentOS as a free and open source alternative to RHEL. It is a community-driven project that was founded by the original creator of CentOS after Red Hat announced that it would shift the focus of CentOS from a stable release to a rolling release. It is suitable for users who want to continue using CentOS as it was before or who need a compatible and independent platform for their applications.
