And for external user access, Internet DNS should be configured to provide name and resolution to your Kubernetes cluster. You'll learn more about what exactly is required in the lessons where we talk about networking. Commonly, external load balancers take care of distributing the workload to Kubernetes resources. But for our setup in this class, we don't have to do any external load balancers. And you need firewall access to a couple of ports.
