Which style of operations are preferred for K8S and cloud native applications?

JSON is a data serialization format used to represent Kubernetes objects, but it's not a style of operations itself; both declarative and imperative commands can use JSON.

Kubernetes operates on a declarative model, meaning users define the desired state of their applications and infrastructure using configuration files (like YAML). The Kubernetes control plane then continuously observes the actual state of the cluster and works to reconcile it with the desired state, automatically managing resources to maintain stability and recover from failures.

Imperative operations involve directly issuing commands to execute actions, specifying *how* to achieve a state. While Kubernetes supports some imperative commands (e.g., `kubectl run`), the preferred and more robust operational style for managing complex, long-lived cloud-native applications is declarative.
