Managing and provisioning a cloud solution infrastructure

You want your Google Kubernetes Engine cluster to automatically add or remove nodes according to CPU load.

What should you do?

  • A Configure a HorizontalPodAutoscaler with a target CPU usage. Enable the Cluster Autoscaler from the GCP Console.
  • B Configure a HorizontalPodAutoscaler with a target CPU usage. Enable autoscaling on the managed instance group for the cluster using the gcloud command.
  • C Create a deployment and set the maxUnavailable and maxSurge properties. Enable the Cluster Autoscaler using the gcloud command.
  • D Create a deployment and set the maxUnavailable and maxSurge properties. Enable autoscaling on the cluster managed instance group from the GCP Console.
Explanation

A HorizontalPodAutoscaler uses a target CPU utilization to adjust the number of workload Pods. GKE Cluster Autoscaler adjusts node-pool capacity to accommodate Pods that cannot be scheduled and can remove unneeded nodes. Together, they provide workload scaling based on CPU and corresponding automatic node scaling.
