This automated n8n workflow tracks hourly cloud spending across AWS, Azure, and GCP. It detects cost spikes or budget overruns in real time, tags affected resources, and sends alerts via email, WhatsApp, or Slack. This ensures proactive cost management and prevents budget breaches. Good to Know AWS, Azure, and GCP APIs must have read access to billing data. Use secure credentials for API keys or service accounts. The workflow runs every hour for near real-time cost tracking. Alerts can be sent to multiple channels (Email, WhatsApp, Slack). Tags are applied automatically to affected resources for easy tracking. How It Works Hourly Cron Trigger – Starts the workflow every hour to fetch updated billing data. AWS Billing Fetch – Retrieves latest cost and usage data via AWS Cost Explorer API. Azure Billing Fetch – Retrieves subscription cost data from Azure Cost Management API. GCP Billing Fetch – Retrieves project-level spend data using GCP Cloud Billing API. Data Parser – Combines and cleans data from all three clouds into a unified format. Cost Spike Detector – Identifies unusual spending patterns or budget overruns. Owner Identifier – Matches resources to their respective owners or teams. Auto-Tag Resource – Tags the affected resource for quick identification and follow-up. Alert Sender – Sends notifications through Email, WhatsApp, and Slack with detailed cost reports. How to Use Import the workflow into n8n. Configure credentials for AWS, Azure, and GCP billing APIs. Set your budget threshold in the Cost Spike Detector node. Test the workflow to ensure all APIs fetch data correctly. Adjust the Cron Trigger for your preferred monitoring frequency. Monitor alert logs to track and manage cost spikes. Requirements AWS Access Key & Secret Key with Cost Explorer Read Permissions. Azure Client ID, Tenant ID, Client Secret with Cost Management Reader Role. GCP Service Account JSON Key with Billing Account Viewer Role. Customizing This Workflow Change the trigger frequency in the Cron node (e.g., every 15 min for faster alerts). Modify alert channels to include additional messaging platforms. Adjust cost spike detection thresholds to suit your organization’s budget rules. Extend the Data Parser to generate more detailed cost breakdowns. Want a tailored workflow for your business?
