This section describes the core architecture of the vCloud Availability for vCloud Director solution.

The architecture of the solution relies on the service provider environment that provides the replication target and the customer, or tenant, environment that employs vSphere Replication to move the data to the service provider. In the service provider environment, multiple components operate together to support replication, secure communication, and storage of the replicated data. Each service provider can support recovery for multiple customer environments that can scale to handle increasing loads for each tenant, and for multiple tenants.

On the tenant side, a single VM instance is deployed in the tenant vSphere environment. This deployment provides management service that is used to oversee the replication operation for each replicated VM. Standard vSphere Replication is used to exchange this information with the service provider infrastructure.
