<p>Specify the load-based auto scaling configuration for a specified layer. For more information, see <a href="https://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-autoscaling.html">Managing Load with Time-based and Load-based Instances</a>.</p> <note> <p>To use load-based auto scaling, you must create a set of load-based auto scaling instances. Load-based auto scaling operates only on the instances from that set, so you must ensure that you have created enough instances to handle the maximum anticipated load.</p> </note> <p> <b>Required Permissions</b>: To use this action, an IAM user must have a Manage permissions level for the stack, or an attached policy that explicitly grants permissions.
