A target tracking scaling policy that automatically adjusts the capacity provider's compute resources to maintain a specified target value by tracking the required CloudWatch metric.

Example

import * as ec2 from 'aws-cdk-lib/aws-ec2';

const vpc = new ec2.Vpc(this, 'MyVpc');
const securityGroup = new ec2.SecurityGroup(this, 'SecurityGroup', { vpc });

const capacityProvider = new lambda.CapacityProvider(this, 'MyCapacityProvider', {
  subnets: vpc.privateSubnets,
  securityGroups: [securityGroup],
  scalingOptions: lambda.ScalingOptions.manual([
    lambda.TargetTrackingScalingPolicy.cpuUtilization(70),
  ]),
});
