This integrated strategy enables your organization to innovate, simplify, protect, and trust with the world's leading enterprise Linux platform.

Innovate: Accelerating your pace of development

Innovation in the enterprise depends on giving developers the best tools and reducing friction in the development cycle. RHEL 10.2 and 9.8 deliver a significant enhancement in this area, particularly through cutting-edge AI assistance and a comprehensive refresh of core developer toolsets.

Enhanced AI assistance for the command-line

The command-line is the core of Linux power, and we're making it smarter than ever.

• goose command for power users: For those who live in the terminal, we're introducing goose, an advanced, optional command-line AI assistant (available in the extensions repository). While the fully supported RHEL command-line assistant remains, goose provides a more powerful experience, connecting to the same trusted AI backend but offering streaming responses and a path for integration with the new model context protocol (MCP) server for RHEL (developer preview). This means faster, more responsive access to the insights and commands you need, reducing the time spent searching for information.
• Improved visual output: The RHEL command-line assistant is also enhanced with color output support. This feature visually separates commands, scripts, and explanations in the output, making information easier to read, understand, and action, increasing productivity for administrators.

The business value: Faster problem resolution, and a quicker path for new administrators to become proficient. This translates into higher developer productivity and accelerated project timelines.

  • Impact: Ready for modern data workloads, including AI/ML vector processing and broader character support.

Simplify: Streamlining operations with image mode

RHEL 10.2 and 9.8 reduces operational overhead by introducing and enhancing features for image mode for RHEL (based on bootc), driving a new paradigm for OS deployment and management. The power of bootable containers (bootc) image mode revolutionizes how the OS is deployed, managed, and updated. The RHEL OS itself is treated as an immutable container image, offering inherent consistency and resilience.

• Pre-download updates with bootc: A new bootc option allows you to download an OS update to a fleet of machines without immediately applying it. This is crucial for managing system uptime, preventing accidental reboots, and performing maintenance on your schedule.
• Streamlined VM provisioning with Bootable Containers and Virtualization Kit (BCVK): For developers and testers, BCVK simplifies moving from a local container build (for example, using Podman) directly to an automatically provisioned ephemeral virtual machine (VM) test environment. This accelerates the testing loop.
• Efficient container storage: By keeping a dedicated, separate copy of the OS in a container store, we reduce local disk space usage and network bandwidth. Critically, this architecture improves resilience by protecting core OS files from container-related actions, such as a podman system reset.
• Logically bound images for scale: This innovation enables organizations to manage diverse system configurations from a single, standardized base image. This cuts down on the need to maintain a multitude of distinct images, simplifying maintenance and updates across a large, diverse fleet.

Management and upgrade automation

Beyond image mode, RHEL provides key tools for simplifying traditional management tasks:

• Enhanced RHEL image builder command: A new command-line interface (CLI) simplifies the creation of custom RHEL images by eliminating the need for a continuously running service. This design is more container-friendly and ideal for seamless integration into CI/CD pipelines, automating image creation.
• Red Hat Enterprise Linux upgrade system role: This Red Hat Ansible Certified Content Collection automates the resolution of common pre-upgrade issues identified by Leapp. By providing a pre-upgrade report and automatically applying fixes, it enables a smoother, more reliable upgrade process, reducing manual intervention.

The business value: Consistent operations across hybrid clouds, reduced disk space and network costs, and decreased maintenance windows. The new image mode capabilities offer greater stability and predictable deployments at scale.

Protect: Preparing for emerging threats

In an era of rising cyber threats, RHEL 10.2 and 9.8 deliver security enhancements that move beyond conventional defense to help address both current vulnerabilities and future existential threats, such as quantum computing.

Customer-controlled security for immutable systems

Enabled in image mode (bootc), sealed images in RHEL 10.2 (technology preview) brings customer-controlled security, offering end-to-end cryptographic integrity protection for the OS. Your organization can use its own secure boot keys to sign images at build time, and configure target systems to trust only internally certified images. This delivers a complete chain of trust, so that every component is cryptographically verified before and during execution, mitigating the risk of a tampered host.

Addressing the quantum threat with Red Hat Certificate System 11.0

The threat of quantum computers breaking today's cryptography is a very real strategic risk. Red Hat Certificate System 11.0, available alongside RHEL, helps address this challenge.

• Post-quantum cryptography (PQC): Red Hat Certificate System 11.0, available alongside Red Hat Enterprise Linux, introduces quantum-resistant signatures (FIPS-204: ML-DSA) and key encapsulation (FIPS-203: ML-KEM) to help organizations meet emerging NIST standards, defending against "harvest now, decrypt later" while future-proofing certificate authenticity.
• Automation for scale: Certificate lifespans are rapidly shrinking (projected to be as low as 47 days by 2029). Manual renewal is unsustainable. Certificate System 11.0 introduces zero-touch provisioning, which uses a secure, one-time password (OTP) to automate certificate issuance. This feature transforms a week of manual effort for 1,000 devices into an automated task taking minutes, enabling compliance and security in a zero-trust architecture.

The business value: Compliance readiness for PQC mandates (potentially as early as 2027), reduced operational risk from expired or unmanaged certificates, and the highest level of cryptographic integrity for your core operating system across the hybrid cloud.

Trust: Dependable upgrades and migration support

The final pillar of RHEL is trust, built on Red Hat's unwavering commitment to stability, support, and a clear path forward.

Streamlined migration and upgrade paths

• Convert and upgrade in a single step with enhanced Leapp: Leapp is now enhanced to allow conversion directly to a supported RHEL environment and simultaneously upgrade to a newer major version in a single command. This consolidated approach reduces downtime and complexity compared to the previous two-step process.
• AI-guided RHEL upgrades powered by Ansible Automation Platform: We are releasing Red Hat Ansible Certified Content that packages Red Hat's decades of accumulated upgrade knowledge and best practices. This content promotes a "fail fast then iterate" approach, providing a tested, automated procedure for in-place upgrades. This allows for delegation of the upgrade process to the most appropriate teams, enabling reliability and control.

The business value: Reduced downtime during upgrades, lower operational costs by consolidating maintenance windows, and the confidence that your move to RHEL is supported by Red Hat's best practices and certified automation.
