TargetCapacitySpecification¶
Structure Class¶
dataclass
¶
Bases: _SerdeShape
The number of units to request. You can choose to set the target
capacity in terms of instances or 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, or both 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
OnDemandOptions
and
SpotOptions.
