Can you explain how Entity works within JPA?

In Kubernetes, network manifests describe objects that manage the network aspects of the cluster and applications. Main types of network manifests:

• NetworkPolicy — defines rules for network access between pods and/or external sources. It allows restricting which pods can communicate with each other or with external services.

• Service — an abstraction that defines how to access a set of pods (e.g., ClusterIP, NodePort, LoadBalancer). It provides a stable IP and DNS for accessing the pods.

• Ingress — manages external access to services, usually via HTTP/HTTPS, with options for routing, SSL, and load balancing.

• Endpoint — an object that stores IP addresses of pods associated with a service.

• Pod — although not purely a network object, a pod manifest contains network configuration specifications, such as ports and annotations.

Each of these manifests is responsible for a certain level of network interaction: from routing and load balancing to security policies and traffic isolation.
