1. Automation Spectrum in Incident Response
Automation in incident playbooks exists on a spectrum:- Manual Execution (Engineers follow step-by-step instructions)
- Semi-Automated (Engineers trigger scripts/commands via ChatOps or runbooks)
- Fully Automated (Self-healing systems execute remediation without human intervention)
- System complexity (e.g., cloud-native vs. legacy infrastructure)
- Failure domain isolation (Can automation safely fix this without cascading failures?)
- Regulatory/compliance requirements (Some industries require human approval for changes.)
2. Key Automation Use Cases in Playbooks
A. Alert Enrichment & Context Gathering Automation can pre-fetch diagnostic data before engineers engage:- PagerDuty workflows that query monitoring systems (Prometheus, Datadog) and attach metrics to incidents.
- ChatOps bots that dump recent logs, deployment history, or topology maps into the incident channel.
- Restarting a stuck service (e.g.,
kubectl rollout restart deployment/{service}
) - Scaling up resources (e.g., AWS Lambda concurrency increase)
- Blocking a malicious IP (e.g., via Cloudflare API)
- Classify incidents for example”Is this a database issue or network flakiness?”)
- Route to the right team based on symptoms (e.g., SRE vs. Data Engineering)
- Follow availability and escalation rules this is the kind of thing that is closely associated with PagerDuty: notifying the person who’s currently on-call, and escalating as needed if that person doesn’t respond
3. Tools & Integration Patterns
Tool | Use Case | Example Integration |
---|---|---|
PagerDuty | Orchestrating workflows, notifications | Auto-trigger AWS Lambda on incident creation |
ChatOps (Slack/MS Teams) | Human-in-the-loop automation | Bot executes kubectl commands after approval |
Runbook Tools (Confluence, Git) | Documentation-as-code | Markdown with embedded Terraform snippets |
Ansible/Chef | Safe, idempotent remediation | Rollback to last known good config |
Serverless (AWS Lambda) | Lightweight automation hooks | Auto-mitigate S3 bucket throttling |
4. Security & Guardrails
Automation introduces risks—fail-safes are critical:- Approval workflows (e.g., “Execute repair? ✅/❌” in Slack)
- Dry-run modes (“What would this script do?”)
- Blast radius control (Limit parallelism, region scoping)
- Audit logs (All actions should be traceable to an incident ID.)
5. Cultural & Organizational Factors
- Start small: Automate only the most repetitive, low-risk tasks.
- Trust through transparency: Engineers should see what automation is doing (e.g., ChatOps command logging).
- Post-mortem feedback loops: Analyze if automation helped or caused issues.
“At one company, we automated DNS failover—until it once failed over unnecessarily. Now it pings the on-call first.”
