# Use CloudFormation to create a scaling policy
<a name="endpoint-scaling-cloudformation"></a>

The following example shows how to configure model auto scaling on an endpoint using CloudFormation.

```
  Endpoint:
    Type: "AWS::SageMaker::Endpoint"
    Properties:
      EndpointName: {{yourEndpointName}}
      EndpointConfigName: {{yourEndpointConfigName}}

  ScalingTarget:
    Type: "AWS::ApplicationAutoScaling::ScalableTarget"
    Properties:
      MaxCapacity: {{10}}
      MinCapacity: {{2}}
      ResourceId: endpoint/{{my-endpoint}}/variant/{{my-variant}}
      RoleARN: {{arn}}
      ScalableDimension: sagemaker:variant:DesiredInstanceCount
      ServiceNamespace: sagemaker

  ScalingPolicy:
    Type: "AWS::ApplicationAutoScaling::ScalingPolicy"
    Properties:
      PolicyName: {{my-scaling-policy}}
      PolicyType: TargetTrackingScaling
      ScalingTargetId:
        Ref: ScalingTarget
      TargetTrackingScalingPolicyConfiguration:
        TargetValue: {{70.0}}
        ScaleInCooldown: {{600}}
        ScaleOutCooldown: {{30}}
        PredefinedMetricSpecification:
          PredefinedMetricType: SageMakerVariantInvocationsPerInstance
```
