Red Hat Enterprise Linux 9 Announced
May 12, 2022

Red Hat introduced Red Hat Enterprise Linux 9, the Linux operating system designed to drive more consistent innovation across the open hybrid cloud, from bare metal servers to cloud providers and the farthest edge of enterprise networks.

Red Hat Enterprise Linux 9 is designed to drive enterprise transformation in parallel with evolving market forces and customer demands in an automated and distributed IT world. The platform will be generally available in the coming weeks.

For two decades, Red Hat Enterprise Linux has served as the backbone of enterprise IT, both in the datacenter and in the cloud, emphasizing customer choice and flexibility. With this platform for innovation, Red Hat customers can choose their underlying architecture, application vendor or cloud provider with the consistency necessary for modern IT. Combined, this has resulted in Red Hat Enterprise Linux becoming an epicenter for innovation.

Building on decades of relentless innovation, the latest version of the world’s leading enterprise Linux platform is the first production release built from CentOS Stream, the continuously delivered Linux distribution that tracks just ahead of Red Hat Enterprise Linux. This approach helps the broader Red Hat Enterprise Linux ecosystem, from partners to customers to independent users, provide feedback, code and feature updates to the world’s leading enterprise Linux platform.

IDC predicts that “by 2023, 40% of G2000 [companies will] reset cloud selection processes to focus on business outcomes rather than IT requirements, valuing access to providers' portfolios from device to edge and from data to ecosystem.” To Red Hat, this indicates that a standardized platform that can reach across all of these footprints and provide an experience optimized for both innovation and production stability is crucial. Red Hat Enterprise Linux 9 is engineered to address these needs and more, enabling operations teams and developers to deploy new initiatives without abandoning existing workloads or systems.

Customers can use Red Hat Enterprise Linux wherever and however it makes sense for their unique operational requirements with broad availability and deployment options across major cloud marketplaces. Existing customers can migrate Red Hat Enterprise Linux subscriptions to the cloud of their choice with Red Hat Cloud Access, while any customer looking to adopt the scale and power of the cloud will be able to deploy the platform on-demand from major cloud provider marketplaces, including Amazon Web Services (AWS), Google Cloud, IBM Cloud and Microsoft Azure.

This platform ubiquity also stretches to the edge. With enterprise interest in edge computing growing and forecasts predicting a market of more than a quarter trillion dollars by 2025. Red Hat Enterprise Linux 9 incorporates key enhancements specifically designed to address evolving IT needs at the edge. These capabilities include:

- Comprehensive edge management, delivered as a service, to oversee and scale remote deployments with greater control and security functionality, encompassing zero-touch provisioning, system health visibility and more responsive vulnerability mitigations all from a single interface.

- Automatic container roll-back with Podman, Red Hat Enterprise Linux’s integrated container management technology, which can automatically detect if a newly-updated container fails to start and then roll the container back to the previous working version.

Red Hat Enterprise Linux 9 also highlights Red Hat’s efforts to deliver key operating system functions as services, starting with a new image builder service. Supporting the core platform’s existing functionality, the service supports image creation for customized filesystems and major cloud providers and virtualization technologies, including AWS, Google Cloud, Microsoft Azure and VMware.

Red Hat and AWS have worked together for more than a decade to support the latest version of Red Hat Enterprise Linux at launch on AWS. Most recently, customers can now run Red Hat Enterprise Linux-based workloads on AWS instances that use ARM-designed Graviton processors. Red Hat Enterprise Linux 9 integration with AWS Graviton processors helps to optimize price performance for a wide range of cloud workloads running in Amazon Elastic Compute Cloud (Amazon EC2).
A stronger backbone for innovation everywhere

As IT teams adopt new technologies and extend into new operating footprints, the threat landscape becomes more dynamic and complex. Red Hat Enterprise Linux 9 retains Red Hat’s commitment to delivering a hardened Linux platform that can handle the most sensitive workloads, pairing innovation with extended security capabilities. Red Hat Enterprise Linux subscriptions also include access to Red Hat Insights, Red Hat’s continuous, proactive analytics service for detecting and remediating potential configuration and vulnerability issues while optimizing resource and subscription usage across the hybrid cloud.

Beyond the hardening, testing and vulnerability scanning that all Red Hat Enterprise Linux releases undergo, Red Hat Enterprise Linux 9 incorporates features which help address hardware-level security vulnerabilities like Spectre and Meltdown as well as capabilities to help user-space processes create memory areas that are inaccessible to potentially malicious code. The platform provides readiness for customer security requirements as well, supporting PCI-DSS, HIPAA and more.

Red Hat Enterprise Linux 9 also introduces integrity measurement architecture (IMA) digital hashes and signatures. With integrity measurement architecture, users can verify the integrity of the operating system with digital signatures and hashes. This helps to detect rogue infrastructure modifications, making it easier to limit the potential for systems to be compromised.

Further supporting enterprise choice in architectures and environments across the open hybrid cloud, Red Hat Enterprise Linux 9 will be available on IBM Cloud and also complements the key security features and capabilities of IBM Power Systems and IBM Z systems. Pairing the security-focused hardware capabilities of IBM’s architectures with the security enhancements in Red Hat Enterprise Linux 9 delivers the innovation, strength and security capabilities that many organizations need in hybrid cloud computing.

As IT systems grow to encompass a wider variety of workloads and footprints, IT operations teams are using automated systems and tooling as force multipliers. Red Hat Enterprise Linux 9 helps IT organizations embrace automation across the hybrid cloud, with capabilities tailored to help cut complexity and enhance manageability.

The platform introduces an expanded set of Red Hat Enterprise Linux System Roles, which provide an automated workflow for creating specific system configurations. Red Hat Enterprise Linux 9 further builds out this selection, adding new System Roles for Postfix, high-availability clusters, firewall, Microsoft SQL Server, web console and more.

Red Hat Enterprise Linux 9 also supports kernel live patching from the Red Hat Enterprise Linux web console, further automating how IT organizations can address critical tasks at scale. This enables IT operations teams to apply updates across large, distributed system deployments without having to access command line tooling, making it easier to address production-impacting issues from the core datacenter to multiple clouds to the edge.

Building on the strategic alliance expanded with Microsoft in 2015, Red Hat Enterprise Linux 9, available at launch on Microsoft Azure, provides a foundation ready for key Microsoft technologies, including Microsoft SQL Server, thanks to joint engineering efforts with Microsoft. This includes tailored performance co-pilot modules, tuned profiles, a SQL Server system role powered by Ansible and more. Red Hat Enterprise Linux 9 also continues to fully support .NET development and applications, bringing applications built using Microsoft’s development platform to the world’s leading enterprise Linux platform.

Red Hat Enterprise Linux 9 will be generally available in the coming weeks via the Red Hat Customer Portal and major cloud provider marketplaces. Red Hat Enterprise Linux 9 is also accessible via no-cost Red Hat Developer programs that provide developers with access to software, how-to videos, demos, getting started guides, documentation and more.
