Difficulty: HardOptimizing Business Processes through FinOps and Cloud Cost Management

A medical SaaS provider operates a telemetry platform on Google Cloud across 40 projects under a single Cloud Billing account. The workload consists of a steady-state API tier on compute resources, predictable database usage, and highly dynamic, bursty data analysis jobs triggered during clinical trial audits. The finance team cannot map costs to specific business units or compute unit costs per active monitoring device, and overall spend is growing faster than revenue. Which combined technical and governance architecture should the Cloud Architect recommend to establish FinOps transparency and maximize cost efficiency?

  1. Export detailed Cloud Billing data to BigQuery at the organization level, enforce standardized resource labeling (such as cost-center and environment) using Organization Policies, purchase Flexible Committed Use Discounts for baseline hourly spend across compute and database services, and use BigQuery autoscaling slots for dynamic analytical workloads.Answer
  2. B
    Purchase 3-year standard Compute Engine Committed Use Discounts locked to specific VM machine families across all projects to capture the highest static discount tier, and manually review monthly billing CSV downloads to allocate costs across business units.
  3. C
    Migrate all regional application relational databases and telemetry analytics pipelines to Cloud Spanner across all environments to consolidate data storage under a single globally managed billing meter.
  4. D
    Assign the primitive Owner role on each project to individual department leads so they can directly modify billing export settings, shut down resources, and adjust resource quotas independently.

Answer

Export detailed Cloud Billing data to BigQuery at the organization level, enforce standardized resource labeling using Organization Policies, purchase Flexible Committed Use Discounts for baseline hourly spend, and use BigQuery autoscaling slots for dynamic workloads.
The correct strategy combines automated billing data ingestion into BigQuery with organizational policy enforcement of resource labels (tags) to establish accurate chargeback and unit-economics tracking. Utilizing Flexible Committed Use Discounts (CUDs) optimizes steady-state spend across services without locking into static VM configurations, and BigQuery autoscaling slots efficiently accommodate bursty analytical workloads.

Step-by-Step Solution

1
Establish centralized visibility and cost attribution.
Detailed Cloud Billing export to BigQuery provides raw data for reporting, while required resource labels (enforced via tag policy/IaC) enable accurate chargeback/showback per business unit and active device metric.
FinOps visibility requires granular data ingestion and structured resource metadata across all 40 projects.
2
Optimize steady-state compute and database spend.
Flexible Committed Use Discounts (CUDs) apply discounts automatically to hourly spend across eligible compute services (e.g., Compute Engine, Cloud Run) and databases regardless of region or machine family.
Spend-based Flexible CUDs mitigate risk compared to rigid instance-based CUDs while securing baseline discounts.
3
Manage unpredictable analytical query costs.
Leveraging BigQuery editions with slot autoscaling handles bursty clinical trial audit analysis without requiring idle reserved slot capacity.
Autoscaling slot reservations balance performance during peak audit cycles with low baseline cost.
