As 2023 comes to a close, it’s a good time to pause and reflect on the year’s accomplishments. There are many highlights along with great support and collaboration across our ecosystem and the open source community.

Keep Linux open and free

Oracle chief corporate architect Edward Screven and head of Oracle Linux development Wim Coekaerts reiterated our Linux strategy in a July blog post by stating, “We want to emphasize to Linux developers, Linux customers, and Linux distributors that Oracle is committed to Linux freedom."

  • In August, Open Enterprise Linux Association (OpenELA) was founded by CIQ, Oracle, and SUSE to collaborate on Enterprise Linux as an open source project to provide open and free Enterprise Linux source code. In November, OpenELA publicly released Enterprise Linux source code and achieved important technical and governance milestones. In December, OpenELA announced the creation of a user documentation repository for the community. These OpenELA announcements exemplify Oracle’s commitment to helping the open source community continue to develop compatible Enterprise Linux distributions and minimize fragmentation.
  • The October webinar, State of the Penguin, with Wim Coekaerts and Robert Shimp, brought attendees up-to-date on Oracle’s contributions to the open source community and how Oracle and other vendors developed the OpenELA to create a common source repository dedicated to Red Hat Enterprise Linux compatibility. Watch the replay.

  • The Oracle Linux engineering team continued to make significant contributions to the kernel, file systems, and tools. For example, Oracle is the #1 contributor to the Linux kernel in 6.1, responsible for the most lines of the code changes in the kernel. By developing innovative features that are shared with the community, Oracle's Linux engineering teams strive to make the operating system better for all. You can find out additional details in our Linux kernel blog posts.

Product and service

Several new product and cloud service releases were introduced this year. 

Oracle Linux 9 Update 3 delivers on Oracle's commitment to open source and keeping Linux free and open while providing binary compatibility to help ensure applications run without disruption.

Update CentOS Linux for free

CentOS Linux 7 will reach end-of-life in June 2024. CentOS Linux 8 ended in December 2021. If your organization relies on CentOS, you are faced with finding an alternative OS. The lack of regular updates puts these systems at increasing risk for major vulnerabilities. 

With Oracle Linux you can continue to benefit from a similar, stable CentOS Linux alternative. Oracle Linux updates and errata are freely available and can be applied to CentOS Linux (not CentOS Stream) or Red Hat Enterprise Linux (RHEL) instances without reinstalling the operating system. Read this blog for a step-by-step guide to moving from CentOS Linux 7 to Oracle Linux 8.

Oracle Linux delivers on security and compliance

Cybersecurity remains a top priority for us all, and 2023 certifications include: 

Oracle Linux completes new Common Criteria certifications

Here is additional insight on this topic:

Infrastructure at scale

As the foundation for Oracle Cloud, with Oracle Cloud Infrastructure (OCI) running on Oracle Linux in all cloud regions globally, we help ensure that customers receive a highly optimized operating system that delivers exceptional performance, scalability, and reliability. In this area:

Oracle Linux powers Oracle Compute Cloud@Customer

Scientific breakthroughs enabled with compute infrastructure using Oracle Linux

One of this year’s most incredible achievements is from a long-standing customer, The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory. They conducted controlled fusion experiments and achieved net energy gain multiple times in 2023—meaning the experiment produced substantially more energy from fusion than the laser energy delivered to drive it. This endeavor requires a highly available and reliable IT/OT compute infrastructure. Read the story, "Ignition! Behind the scenes of Lawrence Livermore Lab’s fusion energy breakthrough".

Growing Oracle Linux ecosystem

As a trusted platform for building robust and secure infrastructure at scale, the Oracle Linux partner ecosystem continued its steady growth.

The Hardware Compatibility List for Oracle Linux and Virtualization and the ISV Catalog provide information on hardware and software that is certified on Oracle Linux.

Free and comprehensive training resources

We constantly expand free and comprehensive training resources such as learning paths, tutorials, hands-on labs, and videos to help users develop applications on Oracle Linux and derive the best value from their deployments on Oracle Linux. Here are highlights of the new training resources added in 2023:
