VMware Telco Cloud Automation: Install, Configure, Manage [V1.8] — Lesson 3: Network function catalogs, CSAR packages, descriptors, workflows, instantiation, placement, scaling, healing, upgrades, termination, and intent policies

Learning Objectives

• Assess dependencies, controls, resilience, and the intended service outcome for Network function catalogs, CSAR packages, descriptors, workflows, instantiation, placement, scaling, healing, upgrades, termination, and intent policies.
• Demonstrate the workflow and leave reproducible evidence in network-function lifecycle trace and policy execution record.
• Recommend a preventive improvement after resolving a scale-out request selecting a site without the required acceleration resources.

Detailed Topics

• Network function catalogs
• CSAR packages
• Descriptors
• Workflows
• Instantiation
• Placement
• Scaling
• Healing
• Upgrades
• Termination
• And intent policies
• Decision ownership, prerequisites, and acceptance evidence for Network function catalogs, CSAR packages, descriptors, workflows, instantiation, placement, scaling, healing, upgrades, termination, and intent policies
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

The instructor builds a representative scenario for Network function catalogs, CSAR packages, descriptors, workflows, instantiation, placement, scaling, healing, upgrades, termination, and intent policies, narrating each decision and showing how it contributes to a managed Telco Cloud Automation platform that onboards cloud infrastructure, orchestrates network functions, applies intent-based workflows, and supports auditable lifecycle operations. The demonstration records network-function lifecycle trace and policy execution record so learners can compare design intent with observable behavior.

Hands-On Exercise

Complete a guided task covering Network function catalogs, CSAR packages, descriptors, workflows, instantiation, placement, scaling, healing, upgrades, termination, and intent policies. Establish a working baseline, reproduce “a scale-out request selecting a site without the required acceleration resources,” isolate the responsible configuration or dependency, apply a reversible fix, and update network-function lifecycle trace and policy execution record with before-and-after proof.

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 Network function catalogs, CSAR packages, descriptors, workflows, instantiation, placement, scaling, healing, upgrades, termination, and intent policies.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how network-function lifecycle trace and policy execution record should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

For a failure in Network function catalogs, CSAR packages, descriptors, workflows, instantiation, placement, scaling, healing, upgrades, termination, and intent policies, separate access, configuration, compute, network, storage, integration, and timing causes. Compare the observed sequence with network-function lifecycle trace and policy execution record; if “a scale-out request selecting a site without the required acceleration resources” is confirmed, document why broader changes were rejected.

Validation Checklist

• Prerequisites and role permissions for Network function catalogs, CSAR packages, descriptors, workflows, instantiation, placement, scaling, healing, upgrades, termination, and intent policies are confirmed before execution.
• The observed result agrees with expected values documented in network-function lifecycle trace and policy execution record.
• Exceptions are explained with evidence instead of being hidden by manual correction.
• The final record names the approver, monitoring point, and next improvement action.

Lesson Outcome

Learners can apply Network function catalogs, CSAR packages, descriptors, workflows, instantiation, placement, scaling, healing, upgrades, termination, and intent policies, explain the decisions made, and defend the result with network-function lifecycle trace and policy execution record.
