on-call rotation

on-call rotation — A scheduled system where team members take turns being responsible for responding to production issues and emergencies outside normal working hours.

In simple English

On-call rotation is a critical practice in software engineering and DevOps where engineers alternate responsibility for monitoring systems and responding to incidents during nights, weekends, or holidays. In a typical rotation, one engineer is designated as on-call for a week or two-week period, meaning they must be available to respond to urgent alerts and production problems at any time. When that period ends, the responsibility passes to the next person on the schedule. This ensures 24/7 coverage without burning out individual engineers. On-call rotations help maintain system reliability and provide a fair distribution of emergency response duties across the team.

Understanding how software teams distribute emergency response duties and maintain 24/7 system coverage fairly.
