One of the nice features of the on-prem version of CDD is being able to invoke deployments with CA RA. The cloud version does not list this as an endpoint, presumably because it's more difficult to traverse across firewalls. Is the intention for those wanting to trigger CA RA deployments from the cloud to use the generic REST endpoint, and open appropriate ports in the firewall? If so, can we rely on a specific IP range from which those calls would be sourced?
