The maximum value to scale to in response to a scale out event. This parameter is required if you are registering a scalable target.
The minimum value to scale to in response to a scale in event. This parameter is required if you are registering a scalable target.
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: service/default/sample-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: instancegroup/j-2EEZNYKUA1NTV/ig-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: table/my-table/index/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: endpoint/my-end-point/variant/KMeansClustering
.
-
Custom resources are not supported with a resource type. This parameter must specify the OutputValue
from the CloudFormation template stack used to access the resources. The unique identifier is defined by the service provider.
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.
The scalable dimension associated with the scalable target. This string consists of the service namespace, resource type, and scaling property.
