The cloud deployment architecture of VMware Cloud Director Availability relies on symmetrical replication operations between cloud environments.

Test and Development Deployment

In a test and development environment, you can deploy the simplest architecture. In the cloud site, a single Combined Appliancehosts the Tunnel Service, the Manager Service, the Cloud Service, and the Replicator Service.

The components with no color in the diagrams represent existing components in the VMware Cloud Director™ environments. The colored components represent the VMware Cloud Director Availability services deployed during the installation and initial configuration. The color of the components indicates which services participate for each replication direction. The replication is always placed at the destination site, and a protection from Cloud Site 1 to Cloud Site 2 uses the Cloud Site 2 VMware Cloud Director Availability services.

Production Deployment

In a production environment, you deploy and configure a Cloud Tunnel Appliance, a Cloud Replication Management Appliance and one or more Cloud Replicator Appliances.

Deploying Multiple VMware Cloud Director Availability Instances in VMware Cloud Director

In a production cloud site, you can deploy one or more VMware Cloud Director Availability instances, distributed in provider virtual data centers (PVDC). A single VMware Cloud Director instance manages all VMware Cloud Director Availability instances, for both a replication source or a replication destination.

In VMware Cloud Director, each VMware Cloud Director Availability instance is registered as a plug-in with its local site name.

In VMware Cloud Director Availability, each PVDC represents a cloud site and the replication traffic can transit directly and securely between each site. In each VMware Cloud Director Availability instance, the service provider controls the accessible PVDC.
