What is the difference between "Horizontal Pod Autoscaler" (HPA) and "Vertical Pod Autoscaler" (VPA)?
Correct! Well done.
Incorrect.
The correct answer is B) HPA automatically adjusts the number of Pod replicas based on observed metrics like CPU or memory usage, while VPA automatically adjusts the resource requests/limits of existing Pods (potentially requiring a restart) based on usage
Correct Answer
HPA automatically adjusts the number of Pod replicas based on observed metrics like CPU or memory usage, while VPA automatically adjusts the resource requests/limits of existing Pods (potentially requiring a restart) based on usage
HPA scales out/in by changing the number of Pods, while VPA scales up/down by adjusting the CPU/memory allocated to individual Pods — they address different scaling dimensions and can sometimes conflict if used together carelessly.
