Getting Started with On-Call Management: A Complete Guide

On-call management is a critical component of modern DevOps and SRE practices. It ensures that when incidents occur, the right people are available to respond quickly and effectively.

What is On-Call Management?

On-call management involves organizing team members to be available outside of normal working hours to respond to critical incidents. This includes:

• Setting up on-call rotations
• Defining escalation policies
• Establishing response time SLAs
• Creating runbooks and playbooks

Key Components

1. On-Call Rotations

Rotations ensure that team members share the burden of being on-call. Common patterns include:

• Fixed Rotations: Team members take turns on a fixed schedule
• Dynamic Rotations: Rotations adjust based on availability
• Load Balancing: Distribute on-call hours evenly across the team

2. Escalation Policies

Escalation policies define what happens when an alert isn't acknowledged or resolved:

• First Responder: The primary on-call engineer
• Escalation Chain: Secondary responders if the first doesn't respond
• Critical Alerts: Immediate escalation for high-severity issues

3. Response Time SLAs

Define clear expectations for response times:

• Critical: 15 minutes or less
• High: 1 hour or less
• Medium: 4 hours or less
• Low: Next business day

Best Practices

1. Document Everything: Create detailed runbooks for common incidents
2. Practice Regularly: Conduct fire drills and incident response exercises
3. Monitor Fatigue: Track on-call load and adjust rotations as needed
4. Learn from Incidents: Conduct post-incident reviews to improve processes

Conclusion

Effective on-call management is essential for maintaining system reliability and team health. By following these practices, you can build a robust on-call system that protects your services while supporting your team.
