In my last blog I explained about Azure Policy, concept and creating it. Next action after creating or changing an policy is to see whether is it working or not. Unlike most other azure features where change are propagated immediately, azure policy trigger does not happen immediately after SAVE.
Interval of Evaluation of policies depend upon type of policy change (new or update), effect and resource deployment.
Following is the evaluation interval
Compliance evaluation frequency
On change (New/Update policy Assignment) ~ 15 min after resource change
On periodic cadence ~ Every 24 hours
On demand ~ 3 min
