Network.AWS.ApplicationAutoScaling.RegisterScalableTarget

Registers or updates a scalable target. A scalable target is a resource that Application Auto Scaling can scale out or scale in. After you have registered a scalable target, you can use this operation to update the minimum and maximum values for its scalable dimension.

After you register a scalable target, you can create and apply scaling policies using PutScalingPolicy . You can view the scaling policies for a service namespace using DescribeScalableTargets . If you no longer need a scalable target, you can deregister it using DeregisterScalableTarget .

Creating a Request

registerScalableTarget

Arguments

:: ServiceNamespace

rstServiceNamespace

-> Text

rstResourceId

-> ScalableDimension

rstScalableDimension

-> RegisterScalableTarget

Creates a value of RegisterScalableTarget with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• rstMaxCapacity - The maximum value to scale to in response to a scale out event. This parameter is required if you are registering a scalable target.
• rstMinCapacity - The minimum value to scale to in response to a scale in event. This parameter is required if you are registering a scalable target.
• rstRoleARN - Application Auto Scaling creates a service-linked role that grants it permissions to modify the scalable target on your behalf. For more information, see Service-Linked Roles for Application Auto Scaling . For resources that are not supported using a service-linked role, this parameter is required and must specify the ARN of an IAM role that allows Application Auto Scaling to modify the scalable target on your behalf.
• rstServiceNamespace - The namespace of the AWS service. For more information, see AWS Service Namespaces in the Amazon Web Services General Reference .
• rstResourceId - The identifier of the resource associated with the scalable target. This string consists of the resource type and unique identifier. * ECS service - The resource type is service and the unique identifier is the cluster name and service name. Example: servicedefaultsample-webapp . * Spot fleet request - The resource type is spot-fleet-request and the unique identifier is the Spot fleet request ID. Example: spot-fleet-request/sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE . * EMR cluster - The resource type is instancegroup and the unique identifier is the cluster ID and instance group ID. Example: instancegroupj-2EEZNYKUA1NTVig-1791Y4E1L8YI0 . * AppStream 2.0 fleet - The resource type is fleet and the unique identifier is the fleet name. Example: fleet/sample-fleet . * DynamoDB table - The resource type is table and the unique identifier is the resource ID. Example: table/my-table . * DynamoDB global secondary index - The resource type is index and the unique identifier is the resource ID. Example: tablemy-tableindex/my-table-index . * Aurora DB cluster - The resource type is cluster and the unique identifier is the cluster name. Example: cluster:my-db-cluster . * Amazon SageMaker endpoint variants - The resource type is variant and the unique identifier is the resource ID. Example: endpointmy-end-pointvariant/KMeansClustering .
• rstScalableDimension - The scalable dimension associated with the scalable target. This string consists of the service namespace, resource type, and scaling property. * ecs:service:DesiredCount - The desired task count of an ECS service. * ec2:spot-fleet-request:TargetCapacity - The target capacity of a Spot fleet request. * elasticmapreduce:instancegroup:InstanceCount - The instance count of an EMR Instance Group. * appstream:fleet:DesiredCapacity - The desired capacity of an AppStream 2.0 fleet. * dynamodb:table:ReadCapacityUnits - The provisioned read capacity for a DynamoDB table. * dynamodb:table:WriteCapacityUnits - The provisioned write capacity for a DynamoDB table. * dynamodb:index:ReadCapacityUnits - The provisioned read capacity for a DynamoDB global secondary index. * dynamodb:index:WriteCapacityUnits - The provisioned write capacity for a DynamoDB global secondary index. * rds:cluster:ReadReplicaCount - The count of Aurora Replicas in an Aurora DB cluster. Available for Aurora MySQL-compatible edition. * sagemaker:variant:DesiredInstanceCount - The number of EC2 instances for an Amazon SageMaker model endpoint variant.
