Does NodePort do load balancing?
A NodePort Service is Part of a Load Balancer Service. In that diagram you showed, the Client would be a pod inside the cluster.
Does Kubernetes service do load balancing?
In other words, Kubernetes services are themselves the crudest form of load balancing traffic. In Kubernetes the most basic type of load balancing is load distribution. Kubernetes uses two methods of load distribution. Both of them are easy to implement at the dispatch level and operate through the kube-proxy feature.
How does NodePort work in Kubernetes?
A NodePort is an open port on every node of your cluster. Kubernetes transparently routes incoming traffic on the NodePort to your service, even if your application is running on a different node. However, a NodePort is assigned from a pool of cluster-configured NodePort ranges (typically 30000–32767).
What is difference between ingress and load balancer?
In simple words, load balancer distributes the requests among multiple backend services (of same type) whereas ingress is more like an API gateway (reverse proxy) which routes the request to a specific backend service based on, for instance, the URL.
What load balancer does Kubernetes use?
Ingress
Currently, however, Ingress is the load-balancing method of choice. Since it is essentially internal to Kubernetes, operating as a pod-based controller, it has relatively unencumbered access to Kubernetes functionality (unlike external load balancers, some of which may not have good access at the pod level).
How Does Load Balancing Work?
Load balancing is defined as the methodical and efficient distribution of network or application traffic across multiple servers in a server farm. Each load balancer sits between client devices and backend servers, receiving and then distributing incoming requests to any available server capable of fulfilling them.

How does a nodeport service work in Kubernetes?
A NodePort service is the most primitive way to get external traffic directly to your service. NodePort, as the name implies, opens a specific port on all the Nodes (the VMs), and any traffic that is sent to this port is forwarded to the service. The YAML for a NodePort service looks like this:
How are services and networking used in Kubernetes?
Containers within a Pod use networking to communicate via loopback. Cluster networking provides communication between different Pods. The Service resource lets you expose an application running in Pods to be reachable from outside your cluster. You can also use Services to publish services only for consumption inside your cluster.
How does the GKE controller work in Kubernetes?
After you deploy this manifest, Kubernetes creates an Ingress resource on your cluster. The GKE Ingress controller creates and configures an HTTP (S) Load Balancer according to the information in the Ingress, routing all external HTTP traffic (on port 80) to the web NodePort Service you exposed.
