What is Runbook?

A documented set of standardized procedures for handling routine operations and incident response in production systems.

Runbooks provide step-by-step instructions for operational tasks like deploying updates, scaling services, responding to alerts, and recovering from failures. They reduce Mean Time To Recovery (MTTR) by giving on-call engineers clear procedures instead of requiring them to diagnose from scratch. Modern runbooks range from simple Markdown documents to interactive notebooks that can execute commands. Runbook automation takes this further by encoding procedures as scripts that can be triggered automatically by monitoring alerts, reducing human intervention and error.
