You can use the Amazon CLI or the Application Auto Scaling API to delete a scaling policy from a variant.

### Delete a scaling policy (Amazon CLI)
<a name="endpoint-auto-scaling-delete-code-cli"></a>

To delete a scaling policy from a variant, use the [delete-scaling-policy](https://docs.amazonaws.cn/cli/latest/reference/application-autoscaling/delete-scaling-policy.html) command with the following parameters:
+ `--policy-name`—The name of the scaling policy.
+ `--resource-id`—The resource identifier for the variant. For this parameter, the resource type is `endpoint` and the unique identifier is the name of the variant. For example, `endpoint/{{my-endpoint}}/variant/{{my-variant}}`.
+ `--service-namespace`—Set this value to `sagemaker`.
+ `--scalable-dimension`—Set this value to `sagemaker:variant:DesiredInstanceCount`.

**Example**  
The following example deletes a target tracking scaling policy named `{{my-scaling-policy}}` from a variant named `{{my-variant}}`, running on the `{{my-endpoint}}` endpoint.  

```
aws application-autoscaling delete-scaling-policy \
  --policy-name {{my-scaling-policy}} \
  --resource-id endpoint/{{my-endpoint}}/variant/{{my-variant}} \
  --service-namespace sagemaker \
  --scalable-dimension sagemaker:variant:DesiredInstanceCount
```

### Delete a scaling policy (Application Auto Scaling API)
<a name="endpoint-auto-scaling-delete-code-api"></a>

To delete a scaling policy from your variant, use the [DeleteScalingPolicy](https://docs.amazonaws.cn/autoscaling/application/APIReference/API_DeleteScalingPolicy.html) Application Auto Scaling API action with the following parameters:
+ `PolicyName`—The name of the scaling policy.
+ `ServiceNamespace`—Set this value to `sagemaker`.
+ `ResourceID`—The resource identifier for the variant. For this parameter, the resource type is `endpoint` and the unique identifier is the name of the variant. For example, `endpoint/{{my-endpoint}}/variant/{{my-variant}}`.
+ `ScalableDimension`—Set this value to `sagemaker:variant:DesiredInstanceCount`.

**Example**  
The following example deletes a target tracking scaling policy named `{{my-scaling-policy}}` from a variant named `{{my-variant}}`, running on the `{{my-endpoint}}` endpoint.
