firstZoneMonitorDurationInSeconds

The period of time, in seconds, that CodeDeploy must wait after completing a deployment to the first Availability Zone. CodeDeploy will wait this amount of time before starting a deployment to the second Availability Zone. You might set this option if you want to allow extra bake time for the first Availability Zone. If you don't specify a value for firstZoneMonitorDurationInSeconds, then CodeDeploy uses the monitorDurationInSeconds value for the first Availability Zone.

For more information about the zonal configuration feature, see zonal configuration in the CodeDeploy User Guide.
