Can you explain what is meant by the term 'service' in the context of Kubernetes?

In Kubernetes, a Service is an abstraction that defines a logical set of Pods and a policy by which to access them. The Service provides a stable IP address and DNS name for a group of Pods, which can change dynamically.

The main purpose of a Service is to ensure stable access to applications running in Pods, despite their restarts or scaling. A Service can load balance traffic among Pods and maintain availability.

Example: If you have multiple Pods running a web application, a Service allows you to access them via a single address, and it will distribute requests among the Pods.
