1. Introduction & Overview
What is Elimination of Toil?
In the context of DevSecOps, elimination of toil refers to the systematic identification and removal of repetitive, manual, automatable, and low-value operational tasks. These tasks do not contribute meaningfully to innovation or system reliability and are typically a drag on productivity.
Toil is any task that is:
- Manual: Performed by a human.
- Repetitive: Occurs frequently and follows the same pattern.
- Automatable: Possible to programmatically execute.
- Tactically reactive: Often urgent and interrupts project work.
History or Background
The concept originates from Google’s Site Reliability Engineering (SRE) discipline. In the Google SRE book, toil is framed as the antithesis of engineering work. The SRE principle aims to automate away toil to improve reliability and developer happiness.
With the rise of DevSecOps, the need to eliminate toil has expanded to security tasks as well, such as:
- Manual security audits
- Repetitive vulnerability patching
- Alert triage and correlation
Why is it Relevant in DevSecOps?
Eliminating toil ensures:
- Faster security feedback loops
- More secure software releases
- Better incident response
- Higher team morale and lower burnout
It enables security to scale at the speed of DevOps, turning security from a blocker into an enabler.
2. Core Concepts & Terminology
Key Terms and Definitions
| Term | Definition |
|---|---|
| Toil | Manual, repetitive, and low-value operational work |
| Automation | Use of tools/scripts to perform tasks without human intervention |
| Runbook Automation | Predefined scripts to respond to alerts or issues automatically |
| Self-healing | Systems that detect and fix issues automatically |
| Observability | Tools and practices to understand system health and performance |
| Security as Code | Defining and managing security policies and controls as code |
How It Fits into the DevSecOps Lifecycle
| Phase | Role of Toil Elimination |
|---|---|
| Plan | Use historical toil data to inform architectural decisions |
| Develop | Automate static code analysis, secret detection |
| Build/Test | CI/CD pipelines with automated testing and SAST |
| Release | Auto-signing, policy validations |
| Deploy | Use GitOps for consistent, secure deployments |
| Operate | Alert correlation, automated remediation, compliance scans |
| Monitor | Automate anomaly detection and reporting |
3. Architecture & How It Works
Components and Workflow
- Toil Identification
- Use metrics, logging, incident records
- Survey engineering teams for feedback
- Automation Tools
- Scripts, bots, runbooks
- CI/CD tools, IaC, configuration management
- Workflow Integration
- Embed into existing pipelines
- Link with monitoring and alerting systems
- Governance & Review
- Regular toil audits
- Security compliance and access controls

Integration Points
| Tool/Platform | Toil Elimination Example |
|---|---|
| Jenkins/GitHub Actions | Automate security scans on pull requests |
| Terraform/CloudFormation | Automate infrastructure deployments |
| Kubernetes | Auto-heal failed pods with liveness/readiness probes |
| AWS Config | Auto-remediation of non-compliant resources |
| Datadog/NewRelic | Auto-create JIRA tickets from alerts |
4. Installation & Getting Started
Basic Setup or Prerequisites
- Familiarity with CI/CD pipelines
- Access to infrastructure-as-code
- Monitoring and logging system in place
- Scripting knowledge (e.g., Bash, Python)
Hands-On: Beginner Setup Guide (CI + Security Scan)
Goal: Eliminate toil by automating a security scan in GitHub Actions.
# .github/workflows/secure-build.yml
name: Secure Build
on: [push]
jobs:
security:
runs-on: ubuntu-latest
steps:
- name: Checkout Code
uses: actions/checkout@v3
- name: Run Secret Scanner
uses: zricethezav/gitleaks-action@v1.4.0
- name: Run Dependency Scan

pip install safety
safety check
Tips
- Store results in an S3 bucket or security dashboard
- Trigger alerts/slack notifications only on new issues to reduce noise
5. Real-World Use Cases
1. Vulnerability Management
- Before: Security teams manually scanned Docker images
- After: CI/CD pipeline integrated with Trivy + auto-policy enforcement
2. Incident Response Automation
- Auto-run a playbook on certain Datadog alerts (e.g., port scan)
- Ansible script blocks IP and logs the event
3. Secret Rotation
- HashiCorp Vault with scheduled secret rotation + GitHub webhook triggers pipeline rebuild
4. Compliance Monitoring
- AWS Config + Lambda = auto-remediate non-tagged resources
- Send compliance reports to Slack and archive in S3
Industry Examples
- Finance: Automate daily audit log checks for tampering
- Healthcare: Auto-validate infrastructure against HIPAA rules
6. Benefits & Limitations
Benefits
- 🕒 Time savings – Less manual intervention
- 📈 Scalability – Teams can handle more services
- 🛡️ Better security – Consistent checks reduce exposure
- 😌 Reduced burnout – Focus on engineering, not firefighting
Limitations
| Challenge | Mitigation |
|---|---|
| False positives in automation | Add contextual alerting |
| Over-automation | Regular human review cycles |
| Initial setup cost | Start small, iterate incrementally |
7. Best Practices & Recommendations
Security Tips
- Enforce RBAC and logging for automation scripts
- Use signed pipelines (e.g., Sigstore)
Performance
- Cache scan results for unchanged code
- Use scalable workers or FaaS for bursty jobs
Maintenance
- Maintain a Toil Backlog in your sprint board
- Run quarterly “Toil Review” meetings
Compliance Alignment
- Use CSPM (Cloud Security Posture Management) tools to auto-check configurations
- Document all automation as part of internal audits
Automation Ideas
- ChatOps: Trigger incident playbooks via Slack
- GitOps: Automate all infrastructure changes via PRs
8. Comparison with Alternatives
| Approach | Pros | Cons |
|---|---|---|
| Manual Workflows | Flexible, human decision making | Slower, error-prone |
| Runbooks (Semi-automated) | Easier to get started | Still needs human action |
| Elimination of Toil | Fully automated, scalable | Needs upfront investment |
When to Choose Elimination of Toil
- You’re experiencing alert fatigue
- Security tasks are slowing down releases
- Your team is growing and manual effort doesn’t scale
9. Conclusion
Elimination of toil is not a one-time effort—it is a cultural and technical shift. In the context of DevSecOps, it directly influences your team’s ability to scale security, reduce burnout, and ship secure software faster. By identifying toil, prioritizing it, and automating it away, you unlock significant improvements in efficiency, reliability, and security posture.
Future Trends
- Increased use of AI/ML to identify and eliminate toil dynamically
