VMware vRealize Automation: Advanced Features and Troubleshooting [V8.x] — Lesson 1: Advanced cloud templates, expressions, dependencies, dynamic inputs, resource mappings, custom resources, allocation helpers, constraints, and reusable design patterns

Learning Objectives

• Assess dependencies, controls, resilience, and the intended service outcome for Advanced cloud templates, expressions, dependencies, dynamic inputs, resource mappings, custom resources, allocation helpers, constraints, and reusable design patterns.
• Demonstrate the workflow and leave reproducible evidence in advanced template test suite and dependency graph.
• Recommend a preventive improvement after resolving a computed constraint resolving to no eligible cloud zone.

Detailed Topics

• Advanced cloud templates
• Expressions
• Dependencies
• Dynamic inputs
• Resource mappings
• Custom resources
• Allocation helpers
• Constraints
• And reusable design patterns
• Decision ownership, prerequisites, and acceptance evidence for Advanced cloud templates, expressions, dependencies, dynamic inputs, resource mappings, custom resources, allocation helpers, constraints, and reusable design patterns
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

The demonstration traces Advanced cloud templates, expressions, dependencies, dynamic inputs, resource mappings, custom resources, allocation helpers, constraints, and reusable design patterns from requirement through execution and review. Learners see where evidence should be collected, how advanced template test suite and dependency graph supports validation, and which warning signs require investigation.

Hands-On Exercise

Configure and test Advanced cloud templates, expressions, dependencies, dynamic inputs, resource mappings, custom resources, allocation helpers, constraints, and reusable design patterns with representative infrastructure or application data. Use “a computed constraint resolving to no eligible cloud zone” as the troubleshooting challenge, compare hypotheses, retest the affected path, and complete advanced template test suite and dependency graph for review.

1. Map the current workflow and mark where the expected result can first be observed.
2. Run the scenario while preserving timestamps, object identifiers, and relevant output.
3. Apply a reversible correction only after evidence supports the cause.
4. Retest the original case plus an unaffected case and update the handover record.

Scenario Analysis

• Clarify the service trigger, affected components and roles, prerequisites, and acceptable result for Advanced cloud templates, expressions, dependencies, dynamic inputs, resource mappings, custom resources, allocation helpers, constraints, and reusable design patterns.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how advanced template test suite and dependency graph should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

For a failure in Advanced cloud templates, expressions, dependencies, dynamic inputs, resource mappings, custom resources, allocation helpers, constraints, and reusable design patterns, separate access, configuration, compute, network, storage, integration, and timing causes. Compare the observed sequence with advanced template test suite and dependency graph; if “a computed constraint resolving to no eligible cloud zone” is confirmed, document why broader changes were rejected.

Validation Checklist

• The scope of Advanced cloud templates, expressions, dependencies, dynamic inputs, resource mappings, custom resources, allocation helpers, constraints, and reusable design patterns is clear, including what is deliberately excluded from the test.
• Evidence in advanced template test suite and dependency graph supports each material decision and outcome.
• A negative test demonstrates that controls reject or expose an invalid condition.
• Open risks, owners, due actions, and production safeguards are documented.

Lesson Outcome

Learners can apply Advanced cloud templates, expressions, dependencies, dynamic inputs, resource mappings, custom resources, allocation helpers, constraints, and reusable design patterns, explain the decisions made, and defend the result with advanced template test suite and dependency graph.
