To initiate a trust establishment between two cloud sites running VMware Cloud Director Availability instances, initiate pairing from either of the two sites. Then, to complete establishing the trust, repeat the pairing procedure in the remote site.

To pair site A and site B, repeat the steps twice and perform the pairing procedure in both cloud sites:
  1. In cloud site A, initiate pairing with site B.
  2. In cloud site B, complete pairing with site A.


  • Verify that, before pairing sites, the versions of VMware Cloud Director Availability in both sites can interoperate together. For the pairing interoperability, see Managing Connections Between Cloud Sites.
  • Verify that in both cloud sites, all the VMware Cloud Director Availability appliances are successfully configured:
    • Cloud Replication Management Appliance
    • Cloud Replicator Appliance instances
    • Cloud Tunnel Appliance


  1. Log in to the management interface of the Cloud Replication Management Appliance.
    1. In a Web browser, go to https://Appliance-IP-Address/ui/admin.
    2. Select Appliance login or SSO login and enter the root or the single sign-on user credentials.
    3. Click Login.
  2. In the left pane under Configuration, click Peer Sites.
  3. On the Cloud sites page, click New Pairing.
  4. In the New Pairing window, configure the pairing with the remote cloud site, and to initiate the trust between the local and the remote cloud sites click Pair.
    Option Description
    Site name Enter a local site name, exactly matching the remote cloud site name.
    Service Endpoint Enter the public URL of the Service Endpoint, external for the remote cloud site. For network port, enter the externally DNAT-ed port, by default port 443. In case both Tunnel Services are internally visible between the two cloud sites, you can enter the internal URL or private IP address of the Tunnel Service and enter port 8048 for direct communication.

    For example, enter

    Description Optionally, enter a description for the paired cloud site.
  5. To complete the first half of the pair process, verify the thumbprint and accept the remote Cloud Service SSL certificate.
    VMware Cloud Director Availability initiates the trust between the two cloud sites.
  6. To complete the pairing, repeat this procedure and log in to the remote cloud site, then pair with the local site.
    VMware Cloud Director Availability establishes the trust between the two cloud sites.
  7. Under Cloud sites, verify that the new cloud site is listed and does not show any errors.
  8. Before creating any replications, verify that as a provider you added each Cloud Service instance for metering in VMware vCloud® Usage Meter.
    For information about adding the cloud sites instances in vCloud Usage Meter, see vCloud Usage Meter Integration.

What to do next

After ensuring the Cloud Service instances are metered by vCloud Usage Meter, you can now start creating and managing replications. You can configure new replications, after modifying the default replication policy for both the source and for the destination organization to allow replications. Alternatively, a custom replication policy that is assigned to the source and to the destination organizations must allow replications. For information about the replication policy, see Configuring Replication Policies in the User Guide.
