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.
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.
