A simple way to picture Azure Automation and Runbooks

Repeating Tasks Automatically

A business repeats tasks (backup, cleanup, reporting) on a schedule. Azure Automation automates such tasks via runbooks, eliminating manual repetition.

How It Actually Works

Automation automates repetitive tasks via runbooks (PowerShell or Python scripts) triggered on schedule or by events, reducing manual overhead.

Walk-Through

1

Create a runbook

A PowerShell or Python script is created.

2

Schedule

The runbook runs on a schedule or trigger.

3

Execute

Automation manages resources per the runbook.

What This Looks Like on the Job

A runbook stops development VMs at 6pm daily to save costs, removing the manual task.
