RH304 – New Features in Red Hat Enterprise Linux — Lesson 3: Podman, Security Enhancements, Identity, Networking, Storage, and Performance

Learning Objectives

• Evaluate integration, security, resilience, performance, and exceptions affecting Podman, security enhancements, and identity.
• Apply networking and storage and performance while preserving reviewable technical evidence.
• Recognize and correct the condition where the implementation succeeds normally but fails during dependency loss, scale, policy enforcement, or recovery.

Detailed Topics

• Podman: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• security enhancements: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• identity: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• networking and storage: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• performance: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.

Instructor Demonstration

The instructor demonstrates podman, security enhancements, identity, networking, storage, and performance by tracing architecture, commands, configuration, system messages, and evidence. The walkthrough tests how the implementation succeeds normally but fails during dependency loss, scale, policy enforcement, or recovery and explains how to isolate the cause without masking related issues.

Hands-On Exercise

Introduce a realistic boundary condition and test corrective behavior for Podman, Security Enhancements, Identity, Networking, Storage, and Performance and add the verified result to the RHEL 10 feature comparison, compatibility assessment, updated procedures, test evidence, and deployment roadmap.

1. Confirm scope, versions, access, dependencies, assumptions, and acceptance criteria.
2. Perform the workflow while recording commands, configuration, output, events, and decisions.
3. Test the normal path and one course-specific exception or boundary condition.
4. Retest the correction and document rollback, ownership, and follow-up actions.

Scenario Analysis

• Identify which dependency most strongly influences Podman in the stated scenario.
• Compare two approaches for networking and storage and explain the security, reliability, performance, and support trade-offs.
• Decide what evidence must be retained in the RHEL 10 feature comparison, compatibility assessment, updated procedures, test evidence, and deployment roadmap before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check integration, security, boundary conditions, resilience, and performance separately, then correlate logs, events, commands, metrics, and configuration history. Treat the assumption that the implementation succeeds normally but fails during dependency loss, scale, policy enforcement, or recovery as a hypothesis until a reproducible retest confirms the cause.

Validation Checklist

• The required integration, security, boundary conditions, resilience, and performance were checked and recorded.
• The normal path and a course-specific exception were tested.
• The RHEL 10 feature comparison, compatibility assessment, updated procedures, test evidence, and deployment roadmap links conclusions to commands, configuration, logs, metrics, or other objective evidence.
• Corrective actions, rollback, ownership, and handover notes are complete.

Lesson Outcome

Learners can apply Podman, Security Enhancements, Identity, Networking, Storage, and Performance, explain the observed platform behavior, and support the result with a reviewable RHEL 10 feature comparison, compatibility assessment, updated procedures, test evidence, and deployment roadmap.
