You can configure your extensibility actions to use an on-premises FaaS provider instead of an Amazon Web Services or Microsoft Azure cloud account.

By using an on-premises FaaS provider for your extensibility actions, you can use on-premises services like LDAP, CMDB, or vCenter data centers in your Cloud Assembly extensibility subscriptions.


Configure an on-premises extensibility action integration. For more information, see Configure an on-premises action-based extensibility integration in Cloud Assembly.
