To protect or migrate vSphere workloads between cloud sites and on-premises vCenter Server deploy one or multiple On-Premises to Cloud Director Replication Appliance instances. The following architecture diagram of the VMware Cloud Director Availability solution shows the protection direction to and from an on-premises site and a cloud site.

In an on-premises vCenter Server environment, every organization Administrator can protect or migrate on-premises workloads to and from a paired cloud site.

On-premises Appliance Deployment

In the on-premises site, deploy and configure one or more On-Premises to Cloud Director Replication Appliance instances as a vSphere Administrator user. Internally, each on-premises appliance instance contains a Replicator Service and a Tunnel Service.

Note: With more than one On-Premises to Cloud Director Replication 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 On-Premises to Cloud Director Replication Appliance installation and configuration procedures.

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

The deployment architecture shows an on-premises appliance on the left and the cloud site on the right.
