To configure VMware Cloud Director Availability in the cloud site, first you perform an initial configuration of the Cloud Service that registers with VMware Cloud Director, with the vCenter Server Lookup service, with the Replicator Service instances, and with the single, or optionally, the dual Tunnel Service instances. Then you can proceed to pair cloud sites.
- One Cloud Director Replication Management Appliance, where the appliance runs the Cloud Service.
- One or more Replicator Appliance instances, where each appliance runs one Replicator Service instance.
- One, or optionally, two Tunnel Appliance instances, where each appliance runs one Tunnel Service instance.
For information about the architecture and each appliance role, see Deployment architecture in the Cloud Director site.
As a best practice, first configure all services in a single cloud site: register the Cloud Service with VMware Cloud Director, with the vCenter Server Lookup service, with the Replicator Service instances in the same site, and with the single or, optionally, dual Tunnel Service instances in active-active mode for high availability (HA).
Then, to allow for pairing, perform the initial configuration and the registration in the remote VMware Cloud Director Availability site.
After configuring the VMware Cloud Director Availability services, you can validate that the setup is complete by opening the service management interface. On the System health page, the entries show green to indicate the successfully configured services.
