Architecting a vCloud Availability for vCloud Director Solution : vRealize Orchestrator Configuration : 7.1 On-Premises Deployment
   
7.1 On-Premises Deployment
A tenant deploys vRealize Orchestrator within its own data center. The vSphere Replication plug-in communicates with the protected vCenter Server and the cloud provider endpoint. All plug-in workflows are available. In summary:
Tenant self-service use case
Simple networking setup
Can be used as an alternative interface to vSphere Web Client UI
Can be used to configure replications to and from the cloud
Can be used to manage migrations and test failovers
In case of complete loss of tenant data center, the tenant loses both the vSphere Replication user interface and vRealize Orchestrator.
