To integrate VCF Automation with an external CMDB (such as ServiceNow) for compliance and tracking of Kubernetes or VM resources, the system utilizes a specific extensibility framework. According to the VCF 9.0 documentation on 'Integrating VCF Automation for ITSM with ServiceNow':

Event Subscriptions (D): These act as the trigger mechanism within the VCF Automation Event Broker Service. When a resource (such as a Kubernetes cluster or deployment) is provisioned, an event is published. An administrator creates a subscription to listen for these specific lifecycle events (e.g., Compute.PostProvision or Kubernetes-specific topics) to initiate the registration process.

VCF Operations orchestrator (B): This is the orchestration engine (formerly known as VMware Aria Automation Orchestrator or vRO). Documentation specifies that for CMDB and ITSM compliance, VCF Automation is integrated with VCF Operations orchestrator workflows. These workflows contain the complex technical logic required to:

Separate objects and feed inputs into technical integration tasks.

Handle API tokens and authentication for the external CMDB.

Execute the REST API calls to the CMDB (e.g., to the cmdb_ci_vmware_instance table).

Update custom properties (like serviceNowSysId) back into the deployment for future decommissioning lifecycle events.

Extract from VCF 9.0 Documentation:

'Enterprise users commonly integrate their Cloud Management Platform with an IT Service Management (ITSM) and Configuration Management Database (CMDB) platform for compliance. Following this example, you can integrate VCF Automation with ServiceNow for CMDB and ITSM using VCF Operations Orchestrator Client... This integration uses Event Subscriptions to trigger VCF Operations Orchestrator workflows.'
