PagerDuty
In plain terms
An incident-response and on-call management platform.
Going deeper
PagerDuty routes alerts to the right on-call responders, manages escalations, and coordinates incident response. It makes sure someone gets paged.
Under the hood
On-call schedules, escalation policies, and integrations reduce mean time to respond.
Examples
On-call rotations, alert routing, incident management, escalations, SRE.
Think of it like...
Like an automated dispatcher that wakes the right engineer when something breaks.
