-- | The number of units to request. You can choose to set the target
-- capacity as the number of instances. Or you can set the target capacity
-- to a performance characteristic that is important to your application
-- workload, such as vCPUs, memory, or I\/O. If the request type is
-- @maintain@, you can specify a target capacity of 0 and add capacity
-- later.
--
-- You can use the On-Demand Instance @MaxTotalPrice@ parameter, the Spot
-- Instance @MaxTotalPrice@ parameter, or both parameters to ensure that
-- your fleet cost does not exceed your budget. If you set a maximum price
-- per hour for the On-Demand Instances and Spot Instances in your request,
-- EC2 Fleet will launch instances until it reaches the maximum amount that
-- you\'re willing to pay. When the maximum amount you\'re willing to pay
-- is reached, the fleet stops launching instances even if it hasn’t met
-- the target capacity. The @MaxTotalPrice@ parameters are located in
-- <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_OnDemandOptionsRequest OnDemandOptionsRequest>
-- and
-- <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_SpotOptionsRequest SpotOptionsRequest>.
