Synopsis

Properties

AllocationStrategy	The strategy that determines the order of the launch template overrides to use in fulfilling On-Demand capacity.
CapacityReservationOptions	The strategy for using unused Capacity Reservations for fulfilling On-Demand capacity.
MaxTotalPrice	The maximum amount per hour for On-Demand Instances that you're willing to pay.
MinTargetCapacity	The minimum target capacity for On-Demand Instances in the fleet.
SingleAvailabilityZone	Indicates that the fleet launches all On-Demand Instances into a single Availability Zone.
SingleInstanceType	Indicates that the fleet uses a single instance type to launch all On-Demand Instances in the fleet.

Properties

AllocationStrategy

The strategy that determines the order of the launch template overrides to use in fulfilling On-Demand capacity.

virtual string AllocationStrategy { get; }

Property Value

System.String

Remarks

lowest-price - EC2 Fleet uses price to determine the order, launching the lowest price first.

prioritized - EC2 Fleet uses the priority that you assigned to each launch template override, launching the highest priority first.

Default: lowest-price

CapacityReservationOptions

The strategy for using unused Capacity Reservations for fulfilling On-Demand capacity.

virtual object CapacityReservationOptions { get; }

Property Value

System.Object

Remarks

Supported only for fleets of type instant .

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-ec2fleet-ondemandoptionsrequest.html#cfn-ec2-ec2fleet-ondemandoptionsrequest-capacityreservationoptions

MaxTotalPrice

The maximum amount per hour for On-Demand Instances that you're willing to pay.

virtual string MaxTotalPrice { get; }

Property Value

System.String

Remarks

If your fleet includes T instances that are configured as unlimited , and if their average CPU usage exceeds the baseline utilization, you will incur a charge for surplus credits. The MaxTotalPrice does not account for surplus credits, and, if you use surplus credits, your final cost might be higher than what you specified for MaxTotalPrice . For more information, see Surplus credits can incur charges in the Amazon EC2 User Guide .

MinTargetCapacity

The minimum target capacity for On-Demand Instances in the fleet.

virtual Nullable<double> MinTargetCapacity { get; }

Property Value

System.Nullable<System.Double>

Remarks

If this minimum capacity isn't reached, no instances are launched.

Constraints: Maximum value of 1000 . Supported only for fleets of type instant .

At least one of the following must be specified: SingleAvailabilityZone | SingleInstanceType
