// For more information, see Managing Load with Time-based and Load-based Instances
// (https://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-autoscaling.html).
//
// 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.
//
// Required Permissions: To use this action, an IAM user must have a Manage
// permissions level for the stack, or an attached policy that explicitly grants
// permissions. For more information on user permissions, see Managing User
// Permissions (https://docs.aws.amazon.com/opsworks/latest/userguide/opsworks-security-users.html).
