{"workflow":{"id":13320,"name":"Monitor multi-cloud costs and enforce policies with OpenAI and Slack alerts","views":43,"recentViews":0,"totalViews":43,"createdAt":"2026-02-12T04:04:27.315Z","description":"## How It Works\nThis workflow automates cloud cost intelligence and governance for organizations struggling with unpredictable cloud spending and budget overruns. Designed for FinOps teams, cloud architects, and finance departments, it solves the critical challenge of monitoring multi-cloud expenses and enforcing cost policies in real-time. The system performs daily cloud cost checks, simulates spending scenarios, analyzes data through dual AI agents (Cost Intelligence Agent identifies optimization opportunities, Governance Agent enforces policies), routes alerts by severity, and notifies stakeholders via Slack and email. By automating cost analysis, anomaly detection, and policy enforcement, organizations prevent budget violations, optimize resource allocation, and maintain financial accountability—essential for enterprises managing complex cloud infrastructures where uncontrolled spending can escalate rapidly.\n\n## Setup Steps\n1. Connect **Daily Trigger** (schedule time aligned with billing cycle updates)\n2. Configure **Cloud Provider APIs** \n3. Add **OpenAI API keys** to Cost Intelligence Agent and Governance Agent nodes\n4. Set budget thresholds and cost policies in Governance Agent prompts\n5. Configure **Slack** webhooks for critical and high-priority alerts\n6. Link **Gmail** credentials for finance team report distribution\n\n## Prerequisites\nCloud provider API access (AWS/Azure/GCP billing), OpenAI API account\n## Use Cases\nMulti-cloud cost optimization, budget compliance enforcement\n## Customization\nModify AI prompts for company-specific cost policies, adjust severity thresholds for alerts\n## Benefits\nPrevents budget overruns through proactive alerts, reduces cloud waste by 30-50%","workflow":{"id":"KnxWZ03iFkRf9Qyd1jU5f","meta":{"instanceId":"b91e510ebae4127f953fd2f5f8d40d58ca1e71c746d4500c12ae86aad04c1502"},"name":"Cloud Cost Intelligence and Governance Orchestration","tags":[],"nodes":[{"id":"fb24ae48-4b1f-4508-9616-a330439e4dfc","name":"Daily Cloud Cost Check","type":"n8n-nodes-base.scheduleTrigger","position":[-816,464],"parameters":{"rule":{"interval":[{"triggerAtHour":8}]}},"typeVersion":1.3},{"id":"6e455dd4-38ba-4a44-897f-82e6d8668528","name":"Workflow Configuration","type":"n8n-nodes-base.set","position":[-592,464],"parameters":{"options":{},"assignments":{"assignments":[{"id":"id-1","name":"costThresholdCritical","type":"number","value":10000},{"id":"id-2","name":"costThresholdHigh","type":"number","value":5000},{"id":"id-3","name":"slackChannelCritical","type":"string","value":"<__PLACEHOLDER_VALUE__Slack Channel ID for Critical Alerts__>"},{"id":"id-4","name":"slackChannelHigh","type":"string","value":"<__PLACEHOLDER_VALUE__Slack Channel ID for High Priority Alerts__>"},{"id":"id-5","name":"financeEmail","type":"string","value":"<__PLACEHOLDER_VALUE__Finance Team Email Address__>"}]},"includeOtherFields":true},"typeVersion":3.4},{"id":"45a9b350-c722-403a-9459-8efcfd8ecf93","name":"Simulate Cloud Spend Data","type":"n8n-nodes-base.set","position":[-368,464],"parameters":{"options":{},"assignments":{"assignments":[{"id":"id-1","name":"cloudProvider","type":"string","value":"AWS"},{"id":"id-2","name":"totalSpend","type":"number","value":12500},{"id":"id-3","name":"previousMonthSpend","type":"number","value":8000},{"id":"id-4","name":"budgetLimit","type":"number","value":10000},{"id":"id-5","name":"topServices","type":"array","value":"[{\"service\": \"EC2\", \"cost\": 5000, \"trend\": \"increasing\"}, {\"service\": \"S3\", \"cost\": 3000, \"trend\": \"stable\"}, {\"service\": \"RDS\", \"cost\": 2500, \"trend\": \"increasing\"}, {\"service\": \"Lambda\", \"cost\": 2000, \"trend\": \"decreasing\"}]"},{"id":"id-6","name":"unusedResources","type":"array","value":"[{\"resourceId\": \"i-abc123\", \"type\": \"EC2 Instance\", \"monthlyCost\": 150}, {\"resourceId\": \"vol-xyz789\", \"type\": \"EBS Volume\", \"monthlyCost\": 50}]"},{"id":"id-7","name":"timestamp","type":"string","value":"={{ $now.toISO() }}"}]},"includeOtherFields":true},"typeVersion":3.4},{"id":"d9fa4b7a-5f80-4bd2-b04c-68fb703d90fe","name":"Cost Intelligence Agent","type":"@n8n/n8n-nodes-langchain.agent","position":[-144,464],"parameters":{"text":"=Cloud Spend Data:\nProvider: {{ $json.cloudProvider }}\nTotal Spend: ${{ $json.totalSpend }}\nPrevious Month: ${{ $json.previousMonthSpend }}\nBudget Limit: ${{ $json.budgetLimit }}\n\nTop Services:\n{{ JSON.stringify($json.topServices, null, 2) }}\n\nUnused Resources:\n{{ JSON.stringify($json.unusedResources, null, 2) }}","options":{"systemMessage":"You are a Cloud Cost Intelligence Agent specialized in analyzing cloud infrastructure spending patterns and identifying optimization opportunities.\n\nYour task is to:\n1.
