CL010 – Red Hat OpenStack Technical Overview — Lesson 3: Networking, Block Storage, Object Storage, Orchestration, and Availability

Learning Objectives

• Evaluate security, resilience, integration, and exception handling for networking, block storage, and object storage.
• Apply orchestration and availability while preserving reviewable technical evidence.
• Recognize and correct the risk where the design works normally but fails under scale, dependency loss, policy enforcement, or integration delay.

Detailed Topics

• networking: 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.
• block storage: 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.
• object storage: 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.
• orchestration: 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.
• availability: 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 networking, block storage, object storage, orchestration, and availability by tracing the relevant architecture, commands, configuration, messages, and evidence. The walkthrough highlights how the design works normally but fails under scale, dependency loss, policy enforcement, or integration delay and shows how to isolate the cause without masking dependent issues.

Hands-On Exercise

Introduce a controlled boundary condition and test recovery for Networking, Block Storage, Object Storage, Orchestration, and Availability. 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 networking in the stated scenario.
• Compare two approaches for orchestration 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 security, integration, boundary conditions, and resilience separately, then correlate logs, events, commands, and configuration history. Do not accept the initial assumption that the design works normally but fails under scale, dependency loss, policy enforcement, or integration delay; confirm the cause with a reproducible retest.

Validation Checklist

• The required security, integration, boundary conditions, and resilience 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 Networking, Block Storage, Object Storage, Orchestration, and Availability, 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.
