使用 Amazon CloudFormation 创建自动扩缩策略

以下示例演示如何使用 Amazon CloudFormation 在端点上激活 Application Auto Scaling。

  Endpoint:
    Type: "AWS::SageMaker::Endpoint"
    Properties:
      EndpointName: yourEndpointName
      EndpointConfigName: yourEndpointConfigName

  ScalingTarget:
    Type: "AWS::ApplicationAutoScaling::ScalableTarget"
    Properties:
      MaxCapacity: 10
      MinCapacity: 2
      ResourceId: endpoint/MyEndPoint/variant/MyVariant
      RoleARN: arn
      ScalableDimension: sagemaker:variant:DesiredInstanceCount
      ServiceNamespace: sagemaker

  ScalingPolicy:
    Type: "AWS::ApplicationAutoScaling::ScalingPolicy"
    Properties:
      PolicyName: myscalablepolicy
      PolicyType: TargetTrackingScaling
      ScalingTargetId:
        Ref: ScalingTarget
      TargetTrackingScalingPolicyConfiguration:
        TargetValue: 75.0
        ScaleInCooldown: 600
        ScaleOutCooldown: 30
        PredefinedMetricSpecification:
          PredefinedMetricType: SageMakerVariantInvocationsPerInstance
