Endpoint		One IP address and port that a service gives, with its load balancing weight. See HTTP API.
Endpoint discovery service	EDS	An HTTP service that gives the endpoints of a service to the clients that poll it, such as Vigie. See How Vigie works.
Endpoint line		One line of a file, a remote list or a TXT record, written host[:port][#weight]. See Endpoint lines.
EndpointSlice		The Kubernetes object that lists the pods behind a Kubernetes Service, read by the kubernetes source. See Read Kubernetes Services.
