It looked at setting up a simple Ingress definition for an example Joomla! site, then extending it to secure with TLS encryption and adding a new rule to route to the Ghost blog. In Kubernetes/GKE case, each "node pool" of a cluster is an "instance group" and GKE Ingress controller configures the LB with instance groups and health checks. If you have a multi-tiered deployment where you want to expose one or more services to the internet using GKE, you can also create an Ingress object, which provisions an HTTP(S) load balancer and allows you to configure path-based or host-based routing to your backend services. A public load balancer has a public IP address that is accessible from the internet. This will become clear through some of the examples that follow. What are the tradeoffs to using one vs. The rules are basically the same, pointing to the same.
