Select No Ingress when firewalls or other networking rules do not allow bi-directional connectivity.
For example, connecting an on-premises system to a cloud deployment where direct connectivity cannot be used. In this scenario, a PrivateLink connection is needed between every on-prem node and every cloud node.
To simplify this setup, a no ingress network can be created and applied from the cloud node to the on-prem nodes. This allows the on-prem nodes to preemptively create connections to the cloud nodes through a PrivateLink connection. This method is often used in conjunction with a load balancer network for on-prem-to-cloud node connectivity.
