An IaaS administrator is responsible for creating the endpoints that allow vRealize Automation to communicate with your infrastructure. A vCloud endpoint is required to connect to a vCloud Director or vCloud Air server.
A vCloud Director or vCloud Air instance is supported by vSphere resources that provide the CPU, memory, and storage for its virtual machines. When vRealize Automation performs data collection on the endpoint, it collects information about the underlying vSphere resources. To avoid conflicts in resource accounting, if you create an endpoint to the vCloud Director instance, do not create an endpoint for its underlying vSphere resources.
For the same vCloud Director instance, you should not set up both organization-specific endpoints and single endpoints that access all organizations.
vRealize Automation uses a proxy agent to manage vSphere resources.
