Step-by-Step: Setting Up a GCP Budget & Alert

1 Open Billing & Navigate to Budgets & Alerts

Log in to the Google Cloud Console. Click the Navigation Menu (☰) in the top-left corner, hover over Billing, and select Budgets & alerts.

2 Click "Create Budget" & Define Budget Scope

Click the CREATE BUDGET button at the top of the page. In Step 1 (Scope), fill out the following:

• Name: Type a descriptive budget name (e.g., Monthly-DevOps-Practice-Budget).
• Time range: Select Monthly (or Quarterly/Yearly).
• Projects: Select All projects or choose a specific GCP project.
• Services: Select All services or pick specific services (like Compute Engine or BigQuery).

3 Set Budget Target Amount ($)

Click Next to move to Step 2 (Amount):

• Budget type: Choose Specified amount (or Last month's spend).
• Target amount: Enter your limit in your billing currency (e.g., 10.00 for $10 USD or 50.00).

4 Configure Alert Trigger Thresholds

Click Next to proceed to Step 3 (Actions). Define your notification trigger rules:

• Threshold 1 (50% Actual): Triggers an email when actual costs reach 50% of your target ($5).
• Threshold 2 (80% Actual): Triggers an email when actual costs reach 80% of your target ($8).
• Threshold 3 (100% Forecasted): Triggers an alert when GCP calculates that your current daily burn rate will exceed 100% by month-end.

5 Configure Email Notifications & Pub/Sub (Optional)

In the notification settings under Actions:

• Ensure Email alerts to billing admins and users is checked.
• (Optional Advanced Setting): Check Connect a Pub/Sub topic to this budget if you want to trigger automated Cloud Functions to stop VMs automatically when a budget is exceeded.

6 Click "Finish" & Monitor Budgets Dashboard

Click FINISH to save your budget. You will be redirected to the Budgets & alerts dashboard, where visual progress bars show real-time spending against your configured limits.
