You can use vRealize Orchestrator or vRealize Automation Designer to extend machine lifecycles.

You can extend machine lifecycles by using vRealize Automation Designer to call out to vRealize Orchestrator, or by using vRealize Orchestrator directly. Both approaches allow you to inject custom logic into predetermined stages of the IaaS machine lifecycle by creating custom vRealize Orchestrator workflows and then insert the custom workflows into the state change workflow stubs. However, you can only restrict custom state change logics to particular blueprints if you are using vRealize Orchestrator directly, and you can only restrict the execution of workflows to specific Distributed Execution Managers by vRealize Automation Designer.

Note:

The workflow stubs are replaced by the event broker workflow subscriptions. They are still available, supported, and they can be used, but expect them to be removed in a future version of vRealize Automation. To ensure future product compatibility, you should use the workflow subscriptions to run custom workflows based on state changes. See Configuring Workflow Subscriptions to Extend vRealize Automation.

Scenario

Procedure

Inject custom logic into predetermined stages of the IaaS machine lifecycle and apply that custom logic to specific blueprints.

Extending Machine Lifecycles by Using vRealize Orchestrator Checklist

Inject custom logic into predetermined stages of the IaaS machine lifecycle and apply that custom logic globally to all of your blueprints.

Extending Machine Life Cycles By Using vRealize Automation Designer Checklist

Restrict execution of workflows to specific Distributed Execution Managers by using skills in vRealize Automation Designer. Skills are similar to a tag that you can apply to both workflows and DEM Worker instances.

For example, you might want to restrict cloud provisioning workflows to a specific DEM running on a host with the required network access to Amazon URLs.
