AWS Azure GCP Multi-Cloud Cost Monitoring & Alerts

This n8n workflow automates real-time cost monitoring across AWS, Azure, and Google Cloud Platform (GCP). It fetches hourly billing data using official APIs (AWS Cost Explorer, Azure Cost Management, GCP Cloud Billing), parses and unifies the data, detects anomalies like spending spikes or budget breaches, identifies resource owners, auto-tags affected resources, and dispatches detailed alerts through multiple channels including email, WhatsApp, and Slack.

Key benefits include preventing unexpected bills through early detection, simplifying multi-cloud cost governance, reducing manual oversight, and enabling quick remediation via resource tagging. It saves significant time for finance and DevOps teams by providing near real-time insights and actionable notifications, potentially cutting cloud costs by 20-30% through proactive management.

Ideal use cases: Enterprises with hybrid multi-cloud environments, SaaS companies scaling infrastructure, DevOps teams managing dynamic workloads, and finance departments enforcing budgets. Configure once with secure API credentials, set custom thresholds, and activate for hands-off operation.

Requires read access to billing APIs; runs every hour for efficiency without overwhelming quotas. Test integrations to ensure data flow before production use.
