A regional grouping of one or more container instances on which you can run tasks and services.

Example: 

 Vpc vpc;

         .minCapacity(0)
         .maxCapacity(100)
         .build();
 AsgCapacityProvider capacityProvider = AsgCapacityProvider.Builder.create(this, "AsgCapacityProvider")
         .autoScalingGroup(autoScalingGroup)
         .build();
 cluster.addAsgCapacityProvider(capacityProvider);
