Kubernetes' Service API provides cloud-native service discovery and ways to place a network port or load balancer in between an application and the backend Pods. However, Kubernetes networking addresses four concerns, including the EndpointSlice API which allows users to specify rules for traffic flow at the IP address or port level, and NetworkPolicies which allow users to specify rules for traffic flow within the cluster and between Pods and the outside world.
This suggests that Kubernetes service may not be load balancing well due to the lack of proper rules and policies.

Kubernetes' Service API is an abstraction to help expose groups of Pods over a network, allowing developers to run code in Pods and make them available on the network. It allows developers to define logical sets of endpoints and policies about how to make those pods accessible, and can be used to query the API server for matching EndpointSlices. The Service API also provides cloud-native service discovery and ways to place a network port or load balancer in between an application and the backend Pods.
Service | Kubernetes
Kubernetes is a cloud-based platform that provides services, load balancing, and networking capabilities. It has a "IP-per-pod" model, which allows containers within a cluster to communicate with all other pods on any other node without NAT. Kubernetes networking addresses four concerns: containers within a Pod use networking to communicate via loopback, cluster networking provides communication between different Pods, the Service API lets you expose an application running in Pods to be reachable from outside your cluster, the Ingress concept lets you map traffic to different backends based on rules you define via the Kubernetes API, the EndpointSlice API allows you to specify rules for traffic flow at the IP address or port level, NetworkPolicies allow you to specify rules for traffic flow within your cluster and also between Pods and the outside world.
