Runbooks

Runbooks are automated incident response workflows. Define a sequence of steps that execute when an alert fires — reducing mean time to resolution (MTTR) and ensuring consistent incident handling.

What Are Runbooks?

A runbook is a predefined sequence of automated actions triggered by an alert condition. Instead of manually following a checklist when something breaks, CloudInfraOS executes the steps for you — or guides an on-call engineer through them.

Runbook Structure

Each runbook consists of:

• Trigger — the alert condition that starts the runbook
• Steps — ordered actions to execute (API calls, notifications, data collection)
• Notifications — who to alert and through which channels
• Execution History — record of every run, with timing and outcomes

Example: High Cost Alert Runbook

1. Trigger: Monthly AWS spend exceeds $5,000 threshold
2. Step 1: Fetch cost breakdown by service from AWS Cost Explorer
3. Step 2: Identify top-spending resources from the last 24 hours
4. Step 3: Send a Slack notification to #finops with the cost breakdown
5. Step 4: Create a tagged audit log entry for compliance

Execution History

Every runbook execution is recorded with its trigger event, step-by-step results, total duration, and final status (completed, failed, or timed out). Use the execution history to audit incident response and improve your runbooks over time.
