TargetCapacitySpecificationRequest
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 OnDemandOptionsRequest
and SpotOptionsRequest.
