Difficulty: HardOptimizing Business Processes through FinOps and Cloud Cost Management

An autonomous mobility company processes real-time vehicle telemetry and operates customer routing APIs on Google Cloud across multiple projects under a unified Cloud Billing Account. The routing API experiences steady, highly predictable traffic year-round, whereas telemetry processing experiences extreme, unpredictable throughput spikes during sudden weather events and peak commuting hours. The finance team requires a FinOps governance framework that minimizes overall operational expenditure, avoids financial commitment risk for unpredictable workloads, and automates cost control enforcement. Which strategy should the Cloud Architect recommend to optimize cost efficiency and FinOps governance?

  1. Apply Spend-Based Flexible Committed Use Discounts (CUDs) at the Cloud Billing Account level for baseline compute and database usage, leverage Cloud Run request-driven scaling for telemetry processing bursts, and configure Organization-level budgets with Pub/Sub notifications for automated cost governance.Answer
  2. B
    Purchase 3-year standard Resource-Based Committed Use Discounts (CUDs) sized to cover peak anticipated telemetry processing capacity across all compute instances to secure the highest available discount percentage.
  3. C
    Migrate all routing APIs and telemetry event processing pipelines into a multi-zonal Google Kubernetes Engine (GKE) Enterprise cluster with statically provisioned node pools covered by 3-year GKE CUDs.
  4. D
    Assign the Project Owner IAM role to billing administrators in each sub-project to enable direct manual resource management and custom billing alert scripts.

Answer

Apply Spend-Based Flexible Committed Use Discounts (CUDs) at the Cloud Billing Account level for baseline compute and database usage, leverage Cloud Run request-driven scaling for telemetry processing bursts, and configure Organization-level budgets with Pub/Sub notifications for automated cost governance.
The correct strategy combines Spend-Based Flexible Committed Use Discounts (CUDs) at the Cloud Billing Account level to cover predictable baseline spend across projects with request-based serverless autoscaling (Cloud Run) for unpredictable spikes. Furthermore, binding Organization-level Cloud Budgets to Pub/Sub enables automated FinOps remediation without operational or security compromises.

Step-by-Step Solution

1
Analyze workload predictability and separate steady-state baseline consumption from bursty workloads.
Identified steady API traffic suitable for commitments and unpredictable telemetry processing requiring dynamic scaling.
Applying long-term financial commitments to unpredictable workloads causes over-commitment waste, while paying on-demand rates for steady baselines wastes potential discount opportunities.
2
Select appropriate commitment models and serverless scaling components for each workload profile.
Selected Flexible CUDs across the billing account for steady baseline spend and Cloud Run serverless autoscaling for burst telemetry.
Flexible CUDs apply hourly spend discounts across regions and compute types without locking into specific machine specs, providing high efficiency and low commitment risk.
3
Implement automated organization-wide FinOps governance controls.
Configured organization-level Cloud Budgets wired to Pub/Sub topics and Cloud Functions for automated budget enforcement.
Programmatic budget alerts prevent cost overruns without relying on risky, manual administrative interventions.
