Services, Load Balancing, and Networking	60	Concepts and resources behind networking in Kubernetes.

Kubernetes networking addresses four concerns:

• Containers within a Pod use networking to communicate via loopback.
• Cluster networking provides communication between different Pods.
• The Service resource lets you expose an application running in Pods to be reachable from outside your cluster.
• You can also use Services to publish services only for consumption inside your cluster.
