Red Hat Ceph Storage for OpenStack – CL260 — Lesson 3: OpenStack Integration, Cinder, Glance, Nova, Authentication, and Security

Learning Objectives

• Evaluate integration, security, resilience, performance, and exceptions affecting OpenStack integration, Cinder, and Glance.
• Apply Nova and authentication and security 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

• OpenStack integration: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• Cinder: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• Glance: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• Nova: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• authentication and security: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.

Instructor Demonstration

The instructor demonstrates openstack integration, cinder, glance, nova, authentication, and security 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 OpenStack Integration, Cinder, Glance, Nova, Authentication, and Security and add the verified result to the Ceph cluster build record, OpenStack integration design, health evidence, capacity plan, and recovery runbook.

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 OpenStack integration in the stated scenario.
• Compare two approaches for Nova and explain the security, reliability, performance, and support trade-offs.
• Decide what evidence must be retained in the Ceph cluster build record, OpenStack integration design, health evidence, capacity plan, and recovery runbook 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 Ceph cluster build record, OpenStack integration design, health evidence, capacity plan, and recovery runbook 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 OpenStack Integration, Cinder, Glance, Nova, Authentication, and Security, explain the observed platform behavior, and support the result with a reviewable Ceph cluster build record, OpenStack integration design, health evidence, capacity plan, and recovery runbook.
