GCP Professional Cloud Architect Practice Question

A travel-booking company runs 200 stateless Java microservices in two-region GKE Autopilot clusters. Weekday average CPU utilization is 50%, but it drops below 10% every weekend. The CFO asks you to cut the steady-state cloud bill while maintaining the current availability SLA. Which architectural change is most likely to yield the greatest ongoing cost savings?

  • Keep GKE Autopilot but buy Standard committed use discounts for a baseline amount of vCPU and memory matching average weekday usage.

  • Replace Autopilot with standard GKE nodes sized to weekday peaks using custom machine types and purchase one-year committed use discounts for the nodes.

  • Migrate the microservices to Cloud Run so they scale to zero during idle periods, and enroll in an enterprise-level spend-based discount program.

  • Enable the GKE cluster autoscaler to use Spot VMs for 60% of the node pool capacity, retaining regular on-demand VMs for the remainder.
