public interface MixedInstancesPolicy

MixedInstancesPolicy allows you to configure a group that diversifies across On-Demand Instances and Spot Instances of multiple instance types.

For more information, see Auto Scaling groups with multiple instance types and purchase options in the Amazon EC2 Auto Scaling User Guide:

https://docs.aws.amazon.com/autoscaling/ec2/userguide/asg-purchase-options.html

Example:

 Vpc vpc;
 LaunchTemplate launchTemplate1;
 LaunchTemplate launchTemplate2;
 AutoScalingGroup.Builder.create(this, "ASG")
         .vpc(vpc)
         .mixedInstancesPolicy(MixedInstancesPolicy.builder()
                 .instancesDistribution(InstancesDistribution.builder()
                         .onDemandPercentageAboveBaseCapacity(50)
                         .build())
                 .launchTemplate(launchTemplate1)
                 .launchTemplateOverrides(List.of(LaunchTemplateOverrides.builder().instanceType(new InstanceType("t3.micro")).build(), LaunchTemplateOverrides.builder().instanceType(new InstanceType("t3a.micro")).build(), LaunchTemplateOverrides.builder().instanceType(new InstanceType("t4g.micro")).launchTemplate(launchTemplate2).build()))
                 .build())
         .build();
