To configure the VMware Cloud Director Availability solution, in a single cloud site you perform an initial configuration of the Manager Service, the Cloud Service, the Replicator Service, and the Tunnel Service. Then you register the services in the cloud site, and pair cloud sites.
As a best practice, configure all services in one cloud site: first register the Replicator Service with the Manager Service in the same site, and to allow for pairing, perform an initial configuration and registration of the second cloud site.
After configuring a VMware Cloud Director Availability service, you can validate that the setup is complete by opening the service management interface to the System Monitoring page. On that page, the entries are green to indicate successfully configured services, and red entries indicate an incomplete setup.
