You can convert an existing vCenter cloud account in vRealize Automation from one that connects to a vCenter server directly to one that connects through a vRealize Automation extensibility (vREx) proxy.

Regardless of whether you use the Forward all traffic through proxy option, vRealize Automation manages the associated vCenter instance with the cloud account. The difference is whether vRealize Automation manages it directly or through an intermediary vRealize Automation extensibility (vREx) proxy.

Reasons you might want to toggle to a remote proxy method include the following:
  • A better throughput for highly loaded vRealize Automation instances.
  • A more reliable connection to distant vCenter servers.
  • The opportunity to manage vCenter servers in network isolation.

You can toggle and test the connection mode.

To change the association of an existing vCenter cloud account from a direct vCenter connection to an indirect, intermediary vRealize Automation extensibility (vREx) proxy, use the following procedure:

  1. Verify that you have the needed prerequisites for managing vCenter cloud account through a vREx proxy. See How can I configure and use a vRealize Automation Extensibility proxy with a vCenter cloud account for improved vRealize Automation performance across data centers.
  2. Log in to vRealize Automation and open the Cloud Assembly service.
  3. Click Infrastructure > Connections > Cloud Accounts and select the existing vCenter cloud account.
  4. In the Credentials area of the cloud account page, select the Forward all traffic through proxy option and select the configuredvRealize Automation extensibility (vREx) proxy from the drop-down menu of available vRealize Automation extensibility (vREx) proxies.

    After you select a vREx proxy, you must revalidate your user name and password credentials.

  5. Revalidate your vCenter credentials as prompted.
  6. Save the changes.
