Services are typically of three types. ClusterIP, NodePort, and LoadBalancers. ClusterIP and NodePort services are for applications internal to infrastructure. For apps that you want to expose externally, you end up using a LoadBalancer service. That's great, but for every end point, you end up having to use another LoadBalancer resource from your cloud provider, and that can end up costing a little bit more.
