VMware 3V0-21.25 - Advanced VMware Cloud Foundation 9.0 Automation

To satisfy the requirement that a registration task must not impact the success of the overall deployment, a Non-blocking event broker subscription must be used. In VCF Automation 9.0, a "Blocking" subscription pauses the provisioning process until the extensibility task completes, allowing the workflow to fail the deployment if the task returns an error. Conversely, a "Non-blocking" subscription operates asynchronously; the platform fires the event and immediately continues with the VM lifecycle regardless of the task's outcome. An Action-Based Extensibility (ABX) action is the ideal lightweight serverless function to execute this registration logic, as it can be easily configured to run in response to the event trigger without the overhead of a full orchestrator workflow. By combining these two, the administrator ensures that the external registration is attempted, and any successes or failures are handled purely within the context of that action and the external service, fulfilling the customer's logging and failure-tolerance requirements.

In VMware Cloud Foundation 9.0, multi-tenancy is structured around the concept of Organizations. To meet the requirement of hosting multiple companies within a single private cloud with strict segregation and governance, the administrator must utilize the VMApps Organization model. Unlike the AllApps model, which is highly optimized for modern containerized and VPC-driven workloads, the VMApps Organization is specifically designed for environments requiring traditional VM-centric segregation and access control while sharing underlying physical infrastructure. Enabling a Supervisor cluster on the vCenter instance is a foundational prerequisite for these advanced automation capabilities. The Supervisor provides the necessary integration between the vSphere compute layer and the VCF Automation control plane, allowing for the instantiation of the Namespace and Organization constructs that enforce RBAC and resource quotas. By configuring a VMApps Organization per company, the administrator ensures that each tenant has a distinct administrative boundary, private catalog, and isolated resource allocation, effectively satisfying the requirements for hard tenancy within a consolidated private cloud environment.

To deliver GPU resources to tenant users in VCF 9.0, the administrator must bridge the physical hardware to the logical project via a Namespace Class. Specifically, the administrator must create or modify a Namespace Class to include VM Class Reservations for GPU-enabled classes. In VCF 9.0, a "Namespace Class" defines the templates and limits for the Kubernetes namespaces that users can create. By adding a GPU-enabled VM Class (such as one utilizing NVIDIA vGPU profiles) to the reservation list within the Namespace Class, the administrator ensures that the Supervisor knows to prioritize and reserve those specific hardware resources for workloads deployed into that namespace. Once this Namespace Class is bound to the user's Project, the users can then select the GPU-enabled classes when deploying their containers or VMs, fulfilling the requirement for high-performance compute within the multi-tenant environment.

When creating a Region for an AllApps Organization in VCF 9.0, the automation engine orchestrates several critical NSX networking components to enable multi-tenancy. The NSX Transit Gateway is deployed to provide the underlying routing backbone that connects different VPCs and external services within the region. Simultaneously, a Default VPC is instantiated for the organization, providing an out-of-the-box isolated environment where developers can immediately begin deploying workloads. To govern how this VPC and others interact with the broader network, a VPC Connectivity Profile is created. This profile defines the "Guardrails" for the organization, such as whether VPCs are strictly isolated (Private - TGW) or have external access. Unlike manual networking setups, these steps are automated during the Region-to-Organization mapping process, ensuring that the necessary multi-tenant infrastructure is consistent and ready for use without manual Tier-1 gateway or segment configuration by the administrator.

To automate CMDB updates in VCF 9.0, administrators leverage the Event Broker Service (EBS) and Custom Forms. First, the administrator can Request additional metadata as input during the blueprint request. This ensures that unique information, such as "Cost Center" or "Application ID," is captured directly from the user at request time. Second, the admin must Configure a subscription that specifically listens for the "Post-Provisioning" event topic. This subscription acts as the trigger for the automation logic. Finally, the subscription invokes an ABX action or Orchestrator workflow that is programmed to Call a webhook endpoint on the CMDB API. This call sends a JSON payload containing both the system-generated metadata (e.g., VM UUID, IP address) and the user-provided inputs directly to the CMDB. This "closed-loop" automation eliminates manual data entry, reduces human error, and ensures that the asset repository is updated in real-time as soon as the infrastructure is live.

To add a certificate to an organization in VMware Cloud Foundation (VCF) Automation, the organization administrator must perform the following three required actions:

Answer

Log into the Organization Portal.

Import the private key.

Import the certificate in PEM format.

In VCF Automation 9.0, managing identity and security at the tenant level is performed within the Organization Portal. This portal allows organization administrators to configure tenant-specific settings, including branding and certificates, independently of the provider.

The requirements for adding a certificate involve these key components:

Administrative Interface: While global infrastructure certificates are managed in the Provider Portal, tenant-specific certificates used for securing an organization's internal services or custom domains are added through the Organization Portal.

Certificate Format: Standard practice for these integrations is to use the PEM (Privacy Enhanced Mail) format, which is a base64 encoded text format widely supported for secure exchanges. The DER (Distinguished Encoding Rules) format is binary and typically not the primary requirement for these web-based portal imports.

Security Pair: To establish a valid, secure connection, both the certificate itself and its associated private key must be imported into the organization's identity store. The private key is essential for the decryption process and must be handled securely during the import process.

Property Groups are the primary mechanism in VCF 9.0 Automation for achieving "reusability" and standardization across multiple cloud templates (blueprints). Instead of manually defining the same inputs or constants in every individual YAML file—which is prone to human error and difficult to update—the administrator creates a centralized group. For the requirements provided, the administrator should Create a Property Group for constants (to hold the salt_master_id) and Create a Property Group for inputs (to hold size, OS, and location). These groups are then associated with the Production Project. The final step is to Update existing blueprints to reference these property groups using the prop syntax. This ensures that if the salt_master_id ever changes, the administrator only needs to update it in one central location, and all associated deployments will automatically reflect the change, significantly reducing operational overhead and ensuring environment consistency.

In VMware Cloud Foundation 9.0, the Virtual Private Cloud (VPC) model utilizes a profile-based approach to standardize and automate network and security services for tenants. The Connectivity Profile is the primary construct used to define the "boundary" of the VPC, determining how the VPC connects to the regional Transit Gateway and whether it has access to external networks or remains isolated. The Security Profile allows administrators to define baseline security postures, such as distributed firewall (DFW) rules and group memberships, that are automatically applied to workloads within the VPC. Finally, the Service Profile is used to enable and configure additional network services, such as Load Balancing or NAT, within the VPC environment. By using these three profile types, the VCF Automation engine can provision consistent, "secure-by-default" network spaces for different organizations or projects, significantly reducing the manual configuration required compared to traditional NSX-T segment management.
