Chapter Summary
In this chapter, you learned that Services provide stable and reliable networking for Pods. They have a front end with a stable DNS name, IP address, and port that Kubernetes guarantees will never change. They also have a back-end that sends traffic to healthy Pods matching a label selector.
ClusterIP Services provide reliable networking on the internal Kubernetes network, NodePort Services expose a port on every cluster node, and LoadBalancer Services integrate with cloud platforms to create highly available internet-facing load balancers.
Finally, Services are first-class objects in the Kubernetes API and should be managed declaratively through version-controlled YAML files.
