kubelet: agent running on each node in the cluster
kube-proxy: network proxy and load balancer for services
container runtime: software responsible for running containers
ClusterIP: default service type, exposes service on a cluster-internal IP
NodePort: exposes service on each node's IP at a static port
LoadBalancer: exposes service externally using a cloud provider's load balancer
