Kubernetes Production Traffic Flow

Follow a production request from the public edge to a workload and back through the observability plane.

Kubernetes Production Traffic Flow

A Kubernetes request is not 'sent to a pod'. It crosses multiple policy, routing and service-discovery boundaries. This diagram makes those boundaries visible so teams can reason about failure domains and telemetry.

01

Every hop creates a separate failure domain.

02

Service discovery and policy are distinct from workload health.

03

Telemetry should cover the request path, not only the pod.

The diagram is intentionally architectural rather than vendor-specific. Use it as a mental model, then map the components to the actual environment.
