Question

Your FinOps team wants to catch cost overruns before they occur rather than after the fact. Each of your 40 project owners currently receives a monthly invoice but no proactive signal. Leadership requires that when a project's spending is trending toward exceeding its monthly budget, an automated workflow disables non-essential resources without any human reading an email. Which Cloud Billing budget configuration best meets this requirement?

Accepted Answer

Create a budget per project with alert thresholds based on forecasted spend, and connect the budget to a Pub/Sub topic that triggers a Cloud Function to disable non-essential resources.

Answer

Create a single organization-wide budget with email notifications to all project owners at 90% and 100% of actual spend.

Answer

Export billing data to BigQuery and schedule a daily query that emails project owners when actual spend exceeds the budget.

Answer

Configure a budget per project with alert thresholds on actual spend only, sending notifications to a Cloud Monitoring notification channel.
