• ✗

  Create a budget with a single threshold of 100% and rely on Cloud Monitoring

  Why it's wrong here

  Setting a single threshold at 100% means you only get alerted when you have exactly reached or exceeded the entire budget; you lose the early-warning signals at 50% and 90%. Relying on Cloud Monitoring does not help because Cloud Monitoring does not automatically ingest Cloud Billing budget thresholds unless you explicitly export billing data and create custom metric-based alerts. Even then, you would need to recreate the threshold logic manually, which is more complex and fragile than using built-in budget threshold rules.

• ✗

  Use Cloud Billing reports to manually track

  Why it's wrong here

  Cloud Billing reports are historical cost views, not an alerting mechanism. An administrator would have to manually open the console and parse the data each time, which does not satisfy the requirement to 'trigger' an alert automatically. Billing data also has lag, so manual tracking would likely miss the 50% and 90% checkpoints in a timely manner.

• ✗

  Create three separate budgets, each with a single threshold

  Why it's wrong here

  While three separate budgets could technically each send an alert at 50%, 90%, and 100%, this approach unnecessarily triplicates the budget configuration and management overhead. A single Cloud Billing budget supports multiple threshold rules, so there is no functional benefit to creating multiple budgets for the same cost scope; it also makes governance more error-prone since any scope change must be replicated across all three budgets.

• ✓

  Create one budget with three threshold rules: 50%, 90%, 100%

  Why this is correct

  Creating one budget with three threshold rules is the recommended and most efficient approach because Cloud Billing budgets natively support multiple thresholds—each can be a percentage of the budget amount and trigger an alert independently. For example, you can set actual-cost thresholds at 50%, 90%, and 100%, and optionally add forecasted-cost thresholds as well. This gives you the desired notification at each stage without duplicating budget resources.
