CL010 – Red Hat OpenStack Technical Overview — Lesson 1: Private Cloud Drivers, OpenStack Architecture, Services, and Control Plane

Learning Objectives

• Interpret the architecture, dependencies, and expected behavior of private cloud drivers, OpenStack architecture, and core services.
• Apply control plane and deployment concepts while preserving reviewable technical evidence.
• Recognize and correct the risk where a hidden prerequisite causes the first configuration step to produce an incomplete result.

Detailed Topics

• private cloud drivers: apply the concept to an infrastructure architecture team evaluating OpenStack for private cloud services, record the relevant settings or decisions, and explain the operational consequence.
• OpenStack architecture: apply the concept to an infrastructure architecture team evaluating OpenStack for private cloud services, record the relevant settings or decisions, and explain the operational consequence.
• core services: apply the concept to an infrastructure architecture team evaluating OpenStack for private cloud services, record the relevant settings or decisions, and explain the operational consequence.
• control plane: apply the concept to an infrastructure architecture team evaluating OpenStack for private cloud services, record the relevant settings or decisions, and explain the operational consequence.
• deployment concepts: apply the concept to an infrastructure architecture team evaluating OpenStack for private cloud services, record the relevant settings or decisions, and explain the operational consequence.

Instructor Demonstration

The instructor demonstrates private cloud drivers, openstack architecture, services, and control plane by tracing the relevant architecture, commands, configuration, messages, and evidence. The walkthrough highlights how a hidden prerequisite causes the first configuration step to produce an incomplete result and shows how to isolate the cause without masking dependent issues.

Hands-On Exercise

Build a baseline and capture the initial state for Private Cloud Drivers, OpenStack Architecture, Services, and Control Plane. Add verified outcomes to the OpenStack capability map, service architecture diagram, suitability assessment, and adoption roadmap.

1. Confirm the scope, versions, access, dependencies, and success criteria.
2. Perform the workflow while recording commands, settings, output, and platform events.
3. Test one expected case and one controlled exception specific to this lesson.
4. Retest the correction and document ownership, rollback, and follow-up actions.

Scenario Analysis

• Identify which dependency most strongly influences private cloud drivers in the stated scenario.
• Compare two approaches for control plane and explain the security, reliability, and support trade-offs.
• Decide what evidence must be retained in the OpenStack capability map, service architecture diagram, suitability assessment, and adoption roadmap before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check architecture, access, dependencies, and starting conditions separately, then correlate logs, events, commands, and configuration history. Do not accept the initial assumption that a hidden prerequisite causes the first configuration step to produce an incomplete result; confirm the cause with a reproducible retest.

Validation Checklist

• The required architecture, access, dependencies, and starting conditions were checked and recorded.
• The normal path and a course-specific exception were tested.
• The OpenStack capability map, service architecture diagram, suitability assessment, and adoption roadmap links conclusions to commands, configuration, logs, or other objective evidence.
• Corrective actions, rollback steps, ownership, and handover notes are complete.

Lesson Outcome

Learners can apply Private Cloud Drivers, OpenStack Architecture, Services, and Control Plane, explain the observed Red Hat platform behavior, and support the result with a reviewable OpenStack capability map, service architecture diagram, suitability assessment, and adoption roadmap.
