CentOS vs RedHat Linux

CentOS and Red Hat Enterprise Linux (RHEL) are two closely related operating systems with some key differences. Here's an overview of the main distinctions between CentOS and RHEL:

Licensing and Support:

• RHEL: Red Hat Enterprise Linux is a commercial distribution that requires a subscription to access official updates, security patches, and support from Red Hat. The subscription provides enterprise-grade support, certifications, and various management tools.
• CentOS: CentOS, short for "Community ENTerprise Operating System," used to be a free and open-source distribution that aimed to provide a binary-compatible alternative to RHEL. However, as of December 2020, the CentOS project shifted its focus with CentOS Stream, which is considered a rolling preview of RHEL and is not identical to RHEL in terms of package stability. This change led to a gap between CentOS Stream and RHEL in terms of stability and compatibility.

Release Cycle:

• RHEL: RHEL follows a stable and predictable release cycle. Each major version is supported for a long period (often around 10 years) with regular updates and security patches.
• CentOS: Before the shift to CentOS Stream, CentOS followed a release cycle that closely mirrored RHEL. However, CentOS Stream, as a rolling preview of RHEL, doesn't have the same fixed release cycle as the traditional CentOS.

Compatibility:

• RHEL: RHEL is used primarily in enterprise environments where stability, long-term support, and compatibility are crucial. It's widely used in production environments where consistency and reliability are essential.
• CentOS: CentOS Stream, due to its rolling nature and its position as a preview of RHEL, might not offer the same level of stability and backward compatibility as traditional CentOS. This can be a concern for businesses that rely on CentOS for its previous stability characteristics.

Use Cases:

• RHEL: RHEL is well-suited for mission-critical applications, production servers, and environments where support and certification are important. It's often used in industries that require regulatory compliance and stringent support agreements.
• CentOS: Before the change to CentOS Stream, traditional CentOS was used in a variety of scenarios where a stable, free, and binary-compatible operating system was needed. However, with the introduction of CentOS Stream, its use cases have become less clear, and organizations that require higher stability have looked for alternatives.

In summary, while CentOS and RHEL share a common foundation and are both based on the source code released by Red Hat, the differences in licensing, support, release cycles, and stability have a significant impact on their suitability for different use cases. RHEL is intended for enterprise customers requiring strong support and stability, while CentOS Stream may be considered more for those looking for a preview of RHEL's future features but with some trade-offs in terms of stability and compatibility. We Can say that CentOS and RedHat Linux are twins in terms of their core functionality,
