 For clarity, this guide defines the following terms:
 
-Node
-: A worker machine in Kubernetes, part of a cluster.
-
-Cluster
-: A set of Nodes that run containerized applications managed by Kubernetes. For this example, and in most common Kubernetes deployments, nodes in the cluster are not part of the public internet.
-
-Edge router
-: A router that enforces the firewall policy for your cluster. This could be a gateway managed by a cloud provider or a physical piece of hardware.
-
-Cluster network
-: A set of links, logical or physical, that facilitate communication within a cluster according to the Kubernetes [networking model](/docs/concepts/cluster-administration/networking/).
-
-Service
-: A Kubernetes {{< glossary_tooltip term_id="service" >}} that identifies a set of Pods using {{< glossary_tooltip text="label" term_id="label" >}} selectors. Unless mentioned otherwise, Services are assumed to have virtual IPs only routable within the cluster network.
