How would you answer an interview scenario involving Gateway API versus Ingress in Ingress?

For an interview scenario involving Gateway API versus Ingress, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Gateway API is a newer Kubernetes networking model with richer role separation and routing capabilities than the original Ingress API. In this scenario, a platform team needs shared gateways while application teams own routes. Explain why Gateway API may fit that responsibility model. For production, evaluate controller maturity, required route types, ownership boundaries, migration strategy, and portability before adopting it. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
