This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::AutoScaling::InstancesDistribution object:

  $service_obj->Method(Att1 => { OnDemandAllocationStrategy => $value, ..., SpotMaxPrice => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::AutoScaling::InstancesDistribution object:

  $result = $service_obj->Method(...);


Describes an instances distribution for an Auto Scaling group with MixedInstancesPolicy.

The instances distribution specifies the distribution of On-Demand Instances and Spot Instances, the maximum price to pay for Spot Instances, and how the Auto Scaling group allocates instance types.


OnDemandAllocationStrategy => Str

  Indicates how to allocate instance types to fulfill On-Demand capacity.

The only valid value is prioritized, which is also the default value. This strategy uses the order of instance type overrides for the LaunchTemplate to define the launch priority of each instance type. The first instance type in the array is prioritized higher than the last. If all your On-Demand capacity cannot be fulfilled using your highest priority instance, then the Auto Scaling groups launches the remaining capacity using the second priority instance type, and so on.

OnDemandBaseCapacity => Int

  The minimum amount of the Auto Scaling group's capacity that must be
fulfilled by On-Demand Instances. This base portion is provisioned
first as your group scales.

The default value is 0. If you leave this parameter set to 0, On-Demand Instances are launched as a percentage of the Auto Scaling group's desired capacity, per the OnDemandPercentageAboveBaseCapacity setting.

OnDemandPercentageAboveBaseCapacity => Int

  Controls the percentages of On-Demand Instances and Spot Instances for
your additional capacity beyond C<OnDemandBaseCapacity>.

The range is 0–100. The default value is 100. If you leave this parameter set to 100, the percentages are 100% for On-Demand Instances and 0% for Spot Instances.

SpotAllocationStrategy => Str

  Indicates how to allocate Spot capacity across Spot pools.

The only valid value is lowest-price, which is also the default value. The Auto Scaling group selects the cheapest Spot pools and evenly allocates your Spot capacity across the number of Spot pools that you specify.

SpotInstancePools => Int

  The number of Spot pools to use to allocate your Spot capacity. The
Spot pools are determined from the different instance types in the
Overrides array of LaunchTemplate.

The range is 1–20 and the default is 2.

SpotMaxPrice => Str

  The maximum price per unit hour that you are willing to pay for a Spot
Instance. If you leave the value of this parameter blank (which is the
default), the maximum Spot price is set at the On-Demand price.

To remove a value that you previously set, include the parameter but leave the value blank.
