SDDC-CMP-VRO-01

Utilize external vRealize Orchestrator instances with default sizing - 2 CPUs, 6 GB memory, and 17 GB of hard disk.

The vRealize Orchestrator appliance requires the appropriate resources to enable connectivity to vRealize Automation via the vRealize Orchestrator Plugin.

External appliances are utilized to ensure isolation between vRealize portal components and customer workflows.

Resources should not be reduced as the vRealize Orchestrator Appliance requires this for scalability.
