OnDemandAllocationStrategy

class aws_cdk.aws_autoscaling.OnDemandAllocationStrategy(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)

Bases: Enum

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

Attributes

LOWEST_PRICE

This strategy uses the lowest-price instance types in each Availability Zone based on the current On-Demand instance price.

To meet your desired capacity, you might receive On-Demand Instances of more than one instance type in each Availability Zone. This depends on how much capacity you request.

PRIORITIZED

This strategy uses the order of instance types in the LaunchTemplateOverrides 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 group launches the remaining capacity using the second priority instance type, and so on.
