Registers or updates a scalable target.
A scalable target is a resource that Application Auto Scaling can scale out and scale in. Scalable targets are uniquely identified by the combination of resource ID, scalable dimension, and namespace.
When you register a new scalable target, you must specify values for minimum and maximum capacity. Current capacity will be adjusted within the specified range when scaling starts. Application Auto Scaling scaling policies will not scale capacity to values that are outside of this range.
After you register a scalable target, you do not need to register it again to use other Application Auto Scaling operations. To see which resources have been registered, use DescribeScalableTargets. You can also view the scaling policies for a service namespace by using DescribeScalableTargets. If you no longer need a scalable target, you can deregister it by using DeregisterScalableTarget.
To update a scalable target, specify the parameters that you want to change. Include the parameters that identify the scalable target: resource ID, scalable dimension, and namespace. Any parameters that you don't specify are not changed by this update request.
If you call the RegisterScalableTarget
API to update an existing
scalable target, Application Auto Scaling retrieves the current capacity
of the resource. If it is below the minimum capacity or above the
maximum capacity, Application Auto Scaling adjusts the capacity of the
scalable target to place it within these bounds, even if you don't
include the MinCapacity
or MaxCapacity
request parameters.

Create a value of RegisterScalableTarget
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:suspendedState:RegisterScalableTarget'
, registerScalableTarget_suspendedState
- An embedded object that contains attributes and attribute values that
are used to suspend and resume automatic scaling. Setting the value of
an attribute to true
suspends the specified scaling activities.
Setting it to false
(default) resumes the specified scaling
activities.
Suspension Outcomes
- For
DynamicScalingInSuspended
, while a suspension is in effect, all scale-in activities that are triggered by a scaling policy are suspended. - For
DynamicScalingOutSuspended
, while a suspension is in effect, all scale-out activities that are triggered by a scaling policy are suspended. - For
ScheduledScalingSuspended
, while a suspension is in effect, all scaling activities that involve scheduled actions are suspended.
For more information, see Suspending and resuming scaling in the Application Auto Scaling User Guide.
$sel:maxCapacity:RegisterScalableTarget'
, registerScalableTarget_maxCapacity
- The maximum value that you plan to scale out to. When a scaling policy
is in effect, Application Auto Scaling can scale out (expand) as needed
to the maximum capacity limit in response to changing demand. This
property is required when registering a new scalable target.
Although you can specify a large maximum capacity, note that service quotas may impose lower limits. Each service has its own default quotas for the maximum capacity of the resource. If you want to specify a higher limit, you can request an increase. For more information, consult the documentation for that service. For information about the default quotas for each service, see Service Endpoints and Quotas in the Amazon Web Services General Reference.
$sel:minCapacity:RegisterScalableTarget'
, registerScalableTarget_minCapacity
- The minimum value that you plan to scale in to. When a scaling policy is
in effect, Application Auto Scaling can scale in (contract) as needed to
the minimum capacity limit in response to changing demand. This property
is required when registering a new scalable target.
For certain resources, the minimum value allowed is 0. This includes Lambda provisioned concurrency, Spot Fleet, ECS services, Aurora DB clusters, EMR clusters, and custom resources. For all other resources, the minimum value allowed is 1.
$sel:roleARN:RegisterScalableTarget'
, registerScalableTarget_roleARN
- This parameter is required for services that do not support
service-linked roles (such as Amazon EMR), and it must specify the ARN
of an IAM role that allows Application Auto Scaling to modify the
scalable target on your behalf.
If the service supports service-linked roles, Application Auto Scaling uses a service-linked role, which it creates if it does not yet exist. For more information, see Application Auto Scaling IAM roles.
$sel:serviceNamespace:RegisterScalableTarget'
, registerScalableTarget_serviceNamespace
- The namespace of the Amazon Web Services service that provides the
resource. For a resource provided by your own application or service,
use custom-resource
instead.
$sel:resourceId:RegisterScalableTarget'
, registerScalableTarget_resourceId
- The identifier of the resource that is 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

. - 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. More information is available in our GitHub repository. - Amazon Comprehend document classification endpoint - The resource
type and unique identifier are specified using the endpoint ARN.
Example:
arn:aws:comprehend:us-west-2:123456789012:document-classifier-endpoint/EXAMPLE

unique identifier are specified using the endpoint ARN. Example:
