What is Kubernetes Service?
An abstraction that provides a stable network endpoint for accessing a group of Pods, handling load balancing and service discovery.
Services provide a stable IP address and DNS name for a set of Pods selected by labels. Types include ClusterIP (internal only), NodePort (external via node ports), LoadBalancer (cloud load balancer), and ExternalName (DNS alias).
Services handle the problem of Pod ephemerality — Pods come and go, but the Service endpoint remains constant. kube-proxy implements load balancing across Pod replicas. Ingress controllers manage external HTTP/HTTPS access to Services.
