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 or not you use the Forward all traffic through proxy option, vRealize Automation manages the associated vCenter server with the cloud account. However, 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:
  • better throughput for highly loaded vRealize Automation instances
  • a more reliable connection to distant vCenter servers
  • opportunity to manage vCenter servers in network isolation

You may also want toggle and test the connection mode. For example, if the cloud account was originally managed directly, you may want to experiment with using vRealize Automation extensibility (vREx) proxy, for example to potentially achieve better throughput or obtain a more reliable connection to the end point.

Use the following procedure to change the association of an existing vCenter cloud account from a direct vCenter server connection to one of an indirect, intermediary vRealize Automation extensibility (vREx) proxy.

  1. Verify that you have met 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 that you want to edit.
  4. In the vCenter Server 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 server credentials as prompted.
  6. Save the changes that you have made to the cloud account.
