Red Hat OpenStack Administration II: Day 2 Operations for Cloud Operators (CL210) — Lesson 4: Automation, Upgrades, Troubleshooting, Recovery, and Operational Improvement

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing automation and upgrade planning.
• Implement and validate failure diagnosis, service recovery, and continuous improvement using reviewable evidence.
• Evaluate the condition where a technically valid implementation creates operational risk because ownership, monitoring, rollback, or handover controls are incomplete and select a proportionate corrective response.

Detailed Topics

• automation applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• upgrade planning applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• failure diagnosis applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• service recovery applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• continuous improvement applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces a cloud operator maintaining a resilient OpenStack environment after initial deployment. The walkthrough connects navigation, commands, configuration logic, system messages, and evidence captured in the OpenStack day-two operations runbook, maintenance plan, monitoring evidence, and incident recovery record. It also tests the exception where a technically valid implementation creates operational risk because ownership, monitoring, rollback, or handover controls are incomplete.

Hands-On Exercise

Complete a controlled Red Hat exercise covering Automation, Upgrades, Troubleshooting, Recovery, and Operational Improvement and preserve the verified result in the OpenStack day-two operations runbook, maintenance plan, monitoring evidence, and incident recovery record.

1. Confirm scope, prerequisites, versions, identities, dependencies, and acceptance criteria.
2. Execute the workflow while recording commands, settings, outputs, events, and system messages.
3. Test normal behavior, one boundary condition, and the stated exception.
4. Document corrections, evidence, ownership, retest criteria, rollback, and handover actions.

Scenario Analysis

• Identify which object, service, policy, setting, or sequence most strongly influences automation.
• Compare two defensible responses and explain technical, security, operational, and support trade-offs.
• Determine how the OpenStack day-two operations runbook, maintenance plan, monitoring evidence, and incident recovery record should be approved, retained, retested, and updated.

Troubleshooting Guidance

Start where expected behavior first differs from the observed result. Check prerequisites, identity, configuration order, version compatibility, connectivity, status, resource limits, and evidence separately. Treat “a technically valid implementation creates operational risk because ownership, monitoring, rollback, or handover controls are incomplete” as a hypothesis until commands, logs, settings, and retest outcomes confirm the cause.

Validation Checklist

• Required platform components, identities, permissions, settings, and dependencies are present.
• The OpenStack day-two operations runbook, maintenance plan, monitoring evidence, and incident recovery record connects each conclusion to objective, reviewable evidence.
• Normal processing, a boundary condition, dependency behavior, and the stated exception were tested.
• Corrections, ownership, retest criteria, rollback, documentation, and operational handover are complete.

Lesson Outcome

Learners can apply Automation, Upgrades, Troubleshooting, Recovery, and Operational Improvement, explain the resulting platform behavior, and defend the outcome through the OpenStack day-two operations runbook, maintenance plan, monitoring evidence, and incident recovery record.
