LoadBalancer is one of the Kubernetes Service types; it automatically creates an external load balancer from the cloud provider and gives the service an IP that can be reached from outside the cluster. Internally it also creates a NodePort and a ClusterIP, and the external load balancer forwards traffic to the port on each node. On-premises clusters have no default implementation, so a separate component such as MetalLB is needed.
