 Using **Ingress** as the cluster endpoint type is a more cost effective way to access your Kubernetes workloads than using type **Load Balancer**, which requires a new cloud Load Balancer to be provisioned for each virtual cluster.
 
-When you enable **Ingress** as the endpoint for a Cluster Group, you must deploy an [Ingress Controller](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers) add-on profile, such as NGINX, on each host cluster in the Cluster Group. The Ingress Controller provides the necessary routing functionality for external traffic to reach the Kubernetes API server of each virtual cluster, as well as any apps each virtual cluster contains.

  - Palette's ```nginx-ingress``` add-on profile automatically reroutes inbound requests from port 6443 to port 443 using a TCP service configuration. This is so that TLS termination on port 443 for all Apps can occur at the cloud load balancer while simultaneously allowing connections to the API servers of your Virtual Clusters on port 6443.
