To replicate to and from the cloud site, in the on-premises vCenter Server deploy one or multiple VMware Cloud Director Availability On-Premises Appliance instances. The architecture of the VMware Cloud Director Availability solution shows the replication operations between the on-premises site and the cloud site.

In a vCenter Server environment, each organization administrator can protect or migrate on-premises workloads to a cloud site. Then fail over the recovered virtual machines from the cloud site back to on-premises sites.

VMware Cloud Director Availability always initiates the network connection from the on-premises site to the cloud site.

On-premises Appliance Deployment

In the on-premises site, deploy and configure one or more VMware Cloud Director Availability On-Premises Appliance instances as a vSphere Administrator user. Each on-premises appliance contains a Replicator Service and a Tunnel Service.

Note: With more than one VMware Cloud Director Availability On-Premises Appliance instance paired with the same organization in the same cloud site, you see the number of replications, recent tasks, traffic, and disk usage of all the on-premises appliance instances paired with the cloud organization, similar to VMware Cloud Director.

In the diagram, the cells without color show the existing components in the on-premises environment. The colored cells show the VMware Cloud Director Availability services that deploy during the VMware Cloud Director Availability On-Premises Appliance installation and configuration procedures.
