![]() ![]() With Application Streams, you can update these components separately from the core operating system and run multiple versions simultaneously. Red Hat Enterprise Linux distributions contain a curated selection of technologies and tools that business-critical applications and services rely on. As a result, you can continue to run the same kernel version while accessing features from newer kernel versions–all without needing to retest or recertify your applications and hardware. Red Hat backports a selection of these features into the existing, stable Red Hat Enterprise Linux kernel. Red Hat also makes commercially reasonable efforts to maintain user space binary compatibility within Red Hat Enterprise Linux major releases and publishes application compatibility guides to help you plan ahead.Īt the same time, the Linux community continues to add new, exciting features to the kernel. All minor releases contain the same kernel version as the associated major release, so you can upgrade with confidence. To help limit the impact of upgrades, Red Hat maintains the same kernel version throughout the life cycle of each major release. Limit disruptions with binary compatibilityįor many IT organizations, changing their Linux kernel version requires application recertifications and process changes, which are often time-consuming and disruptive. And of course, Red Hat Enterprise Linux roadmaps are published well in advance to help you make the best choices for your organization. On the other extreme, you can upgrade your major release as often as every 3 years to take advantage of new features and capabilities right away. For example, if you standardize on a major release for the full 10-year life cycle, you can potentially skip 2 major versions when upgrading to the next major release. This release cadence gives you more choice and flexibility when planning your operating system life cycle. Because major releases are updated every 6 months via a minor release for the first 5 years, 2 major releases are often updated at the same time. Red Hat launches a new major release of Red Hat Enterprise Linux every 3 years. With the Extended Update Support (EUS) and Enhanced Extended Update Support Add-ons for select minor releases, you can extend support-including bug fixes and security patches-for up to 4 years after the initial minor release date. Sometimes you might discover that you need to limit disruptions and remain on a minor release for longer than 6 months. And for organizations that need to remain on a major release for more than 10 years, Red Hat offers the Extended Life Cycle Support (ELS) Add-on to extend the viability of a given major release beyond the standard life cycle. These updates are called errata advisories and are released every 6 months in a minor release, or individually on an as-needed basis.įor the next 5 years, Red Hat provides maintenance support with Red Hat-defined Critical and Important Impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) released on an as-needed basis. Major releases of Red Hat Enterprise Linux have a 10-year life cycle, giving you the opportunity to standardize on a major release for over a decade.ĭuring the first 5 years, Red Hat provides full support, including bug fixes, security patches, software enhancements, hardware enablement, and backports. ![]() Gain visibility into your operating system life cycle To help you plan for change on your own schedule, Red Hat Enterprise Linux offers multiple flexible, enterprise-focused life cycle options that let you plan and upgrade with confidence. Performance enhancements can improve compute resource utilization and help control costs across your entire hybrid cloud environment.Īs a foundational layer of your IT infrastructure, operating system life cycle planning is especially important–end-of-maintenance dates, upgrade options, and software compatibility can significantly impact your IT operations and business. ![]() Security patches fix potential vulnerabilities and help protect your sensitive applications and data. New operating system features can often take advantage of advanced hardware capabilities that already exist in your datacenter. Compounding all of this, upgrading to new versions of foundational software like operating systems and container platforms can be a major project for your entire team.Įven so, there are still many good reasons to keep your infrastructure software updated. ![]() Additionally, short software life cycles require more frequent updates, testing, and recertification. Lack of visibility into vendor roadmaps can make it almost impossible to understand when new releases and features will be available. If you’ve spent time in IT operations, you know that IT life cycle planning can be complicated. ![]()
