RH018 – Virtualization and Infrastructure Migration Technical Overview — Lesson 2: Infrastructure Discovery, Application Assessment, Dependencies, and Readiness

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing asset discovery and workload classification.
• Implement and validate dependency mapping, compatibility, and readiness criteria using reviewable evidence.
• Evaluate the condition where a change succeeds in one environment but fails elsewhere because inventory, policy, version, or runtime assumptions differ and select a proportionate corrective response.

Detailed Topics

• asset discovery applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• workload classification applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• dependency mapping applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• compatibility applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• readiness criteria applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces an architecture team evaluating how to modernize a mixed virtualization estate and migrate workloads with controlled risk. The walkthrough connects navigation, commands, configuration logic, system messages, and evidence captured in the virtualization assessment, migration option analysis, risk register, and phased modernization roadmap. It also tests the exception where a change succeeds in one environment but fails elsewhere because inventory, policy, version, or runtime assumptions differ.

Hands-On Exercise

Complete a controlled Red Hat exercise covering Infrastructure Discovery, Application Assessment, Dependencies, and Readiness and preserve the verified result in the virtualization assessment, migration option analysis, risk register, and phased modernization roadmap.

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 asset discovery.
• Compare two defensible responses and explain technical, security, operational, and support trade-offs.
• Determine how the virtualization assessment, migration option analysis, risk register, and phased modernization roadmap 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 change succeeds in one environment but fails elsewhere because inventory, policy, version, or runtime assumptions differ” 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 virtualization assessment, migration option analysis, risk register, and phased modernization roadmap 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 Infrastructure Discovery, Application Assessment, Dependencies, and Readiness, explain the resulting platform behavior, and defend the outcome through the virtualization assessment, migration option analysis, risk register, and phased modernization roadmap.
