HPA is generic autoscaling for pods based on resource metrics, you need node autoscaling so I'd design this with AKS autoscaler
Azure Functions Consumption plan = event‑driven scaling That is KEDA, not HPA. HPA = resource-driven, based on CPU/Mem; KEDA = event-driven So the pair is: KEDA → event-driven scaling (same mechanism) Cluster Autoscaler → ensure nodes exist when pods scale This is why the correct combination is: ✔️ E. KEDA ✔️ C. Cluster Autoscaler
A --- Cannot scale based on Azure Queue Storage; KEDA manages HPA automatically
