Organizations are accelerating their digital transformation processes for long-term growth and often looking to run their workloads on-premises and in cloud environments. Linux has proven to be a critical technology, especially well-suited for cloud computing. However, not all Linux distributions offer the same benefits. Enterprises need a distribution that delivers specialized features, scalability, and leading performance to help bring products to market faster. Oracle Linux, a secure and optimized operating environment, is at the forefront of helping organizations innovate and is supported across on-premises and multicloud environments.
Oracle's business operations, product development, and public cloud, Oracle Cloud Infrastructure (OCI), all run on Oracle Linux. Because consistency is key to transformation and business agility, we offer our customers the same Linux that we use, including the performance and reliability tunings we perform. We also provide our customers with testing that we carry out across a large footprint. But that's not all. We integrate and test Oracle Linux with all the open source DevOps and cloud native tools that you need to drive innovation: Kubernetes, Ansible-based automation, KVM-based virtualization, and more. And we make it easy to adopt: A single support offering has it all.
We’re immersed both in the Oracle Linux ecosystem and the global open source Linux community. Oracle developers not only contribute millions of lines of code, but many of them are maintainers of Linux’s critical elements. They also collaborate with other contributors from the Linux community.
In this blog, we discuss how Oracle continues to be a top-tier Linux contributor, and how Oracle Linux helps deliver superior performance and top-notch security for you to innovate, build once and deploy across on-premises and multicloud environments, and expedite time to market.
To help Linux run well, from data centers to the cloud, Oracle’s Linux kernel team is involved with the development of many new features and is constantly making improvements to the code. This involvement enables scalable performance and high availability for business-critical workloads that rely on Linux. Recently, for the Linux kernel 6.1 release, Oracle was responsible for the most lines of code changed, making it the top contributor to the release. One of the most significant contributions to the release was the official integration of the Maple Tree data structure. Impactful work also continues to be done for XFS, especially through XFS Online Repair.
In Linux, blocks of virtual memory are split into areas, each described by a virtual memory area (VMA) structure, vm_area_struct
. A process can have a VMA for its code, another VMA for the memory it uses while running, and so on. Because practically everything that runs on Linux involves memory, operations, such as lookups and modifications, on such structures characterizing VMAs must be fast and efficient. Maple Tree is a lockless B-tree data structure that has been designed to efficiently use CPU cache, significantly reduce contention on the memory management subsystem, and overall increase the performance of applications running on Linux systems.
Online Repair, which has been in the works for multiple years, is a remarkable and substantial change for XFS. It permits XFS corruptions to be validated—without having to unmount filesystems—and even repair them online, ultimately allowing for high availability.
Oracle Linux is engineered to increase the performance and stability of enterprise applications, from data-heavy to compute-intensive. Oracle Linux provides a 100% application binary compatible alternative to Red Hat Enterprise Linux (RHEL). The Unbreakable Enterprise Kernel (UEK) for Oracle Linux is highly optimized to deliver performance improvements and the latest security patches, helping customers to continue innovating. On top of realizing performance gains, Oracle Linux Premier Support enables customers to reap powerful, cost-effective solutions to build and deploy products at scale. Along with 24/7 technical support from Oracle experts, you can help strengthen your systems with many Premier Support offerings, such as Oracle Ksplice, Oracle Linux Automation Manager, and Oracle Cloud Native Environment.
Support for the following benefits is included in Oracle Linux Premier Support:
With support for modern programming languages including Java, Python, Node.js, Go, Ruby, and PHP, Oracle Linux offers developers the freedom to choose the tools and languages that work best for them.
Customers with OCI subscriptions benefit from all the offerings of Premier Support at no extra cost. Furthermore, OCI customers can use Oracle Autonomous Linux systems that stay patched and have automatic self-tuning capabilities, helping to eliminate human error and management complexity. Autonomous Linux helps customers avoid security vulnerabilities due to pending patches while being able to maintain low operating costs in OCI.
You can download, use, and distribute Oracle Linux free of charge from the Oracle Linux yum server. You can also obtain the latest security updates, bug fixes, and errata for Oracle Linux for free. If you have an OCI subscription, in a few clicks, you can launch Oracle Linux-based compute instances with preinstalled Oracle Cloud Infrastructure utilities and start developing in minutes.
