-- | An instance type configuration for each instance type in an instance
-- fleet, which determines the EC2 instances Amazon EMR attempts to
-- provision to fulfill On-Demand and Spot target capacities. When you use
-- an allocation strategy, you can include a maximum of 30 instance type
-- configurations for a fleet. For more information about how to use an
-- allocation strategy, see
-- <https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-instance-fleet.html Configure Instance Fleets>.
-- Without an allocation strategy, you may specify a maximum of five
-- instance type configurations for a fleet.
--
-- The instance fleet configuration is available only in Amazon EMR
-- versions 4.8.0 and later, excluding 5.0.x versions.
