Oracle Linux vs Red Hat Enterprise Linux: What are the differences?

1. Licensing Model: One significant difference between Oracle Linux and Red Hat Enterprise Linux is the licensing model. Oracle Linux follows an open-source approach, allowing users to download and use the operating system for free. In contrast, Red Hat Enterprise Linux is a commercial product that requires a subscription for access to updates and support.

2. Support Options: Another crucial difference is the support options provided by each distribution. Red Hat offers comprehensive support services, including 24/7 technical support, access to knowledge bases, and regular updates. On the other hand, Oracle Linux support is more limited, with fewer services available to free users.

3. Package Management: Red Hat Enterprise Linux uses the Yellowdog Updater, Modified (YUM) package manager for software installation and updates. In contrast, Oracle Linux utilizes the Unbreakable Linux Network (ULN) for package management, which is specific to Oracle's Linux distribution.

4. Kernel Modifications: Oracle Linux comes with its own kernel, which includes optimizations and enhancements tailored for Oracle systems and workloads. In contrast, Red Hat Enterprise Linux uses the standard Linux kernel with backported patches and fixes from newer versions.

5. Certifications and Partnerships: Red Hat Enterprise Linux has a strong ecosystem of certified hardware and software partners, ensuring compatibility and support for a wide range of products. Oracle Linux, on the other hand, may have a narrower set of certifications and partnerships due to its specific focus on Oracle products and services.

6. Pricing Structure: While Oracle Linux can be downloaded and used for free, users may need to pay for additional features, support, or certifications. In contrast, Red Hat Enterprise Linux's subscription-based model includes access to updates, support, and certifications as part of the package.

In Summary, Oracle Linux and Red Hat Enterprise Linux differ in their licensing models, support options, package management systems, kernel modifications, certifications, and pricing structures.
