Resource Purpose
Service Stable network endpoint in front of a set of pods (selected by labels)
Service types ClusterIP (internal), NodePort (exposes via node IP), LoadBalancer (cloud LB), ExternalName (DNS alias)
Ingress HTTP/HTTPS routing into the cluster (hostnames, paths). Needs an Ingress Controller (nginx, Traefik, ALB Controller)
NetworkPolicy Firewall rules between pods (requires CNI support, e.g., Cilium)
