+### Azure policy support
+Administrators can use a built-in [Azure Policy](./../governance/policy/overview.md) definition to enfore auto-stop on all compute instances in a given subscription/resource-group.

+2. Under "Definitions", look for the idle shutdown policy.

+
+3. Assign policy to the necessary scope.
+
+You can also create your own custom Azure policy. For example, if the below policy is assigned, all new compute instances will have auto-stop configured with a 60 minute inactivity period.
