Synopsis
Properties
AllocationStrategy | Indicates how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the EC2 Fleet. |
InstanceInterruptionBehavior | The behavior when a Spot Instance is interrupted. |
InstancePoolsToUseCount | The number of Spot pools across which to allocate your target Spot capacity. |
MaintenanceStrategies | The strategies for managing your Spot Instances that are at an elevated risk of being interrupted. |
MaxTotalPrice | The maximum amount per hour for Spot Instances that you're willing to pay. |
MinTargetCapacity | The minimum target capacity for Spot Instances in the fleet. |
SingleAvailabilityZone | Indicates that the fleet launches all Spot Instances into a single Availability Zone. |
SingleInstanceType | Indicates that the fleet uses a single instance type to launch all Spot Instances in the fleet. |
Properties
AllocationStrategy
Indicates how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the EC2 Fleet.
virtual string AllocationStrategy { get; }
Property Value
System.String
Remarks
If the allocation strategy is lowestPrice
, EC2 Fleet launches instances from the Spot Instance pools with the lowest price. This is the default allocation strategy.
If the allocation strategy is diversified
, EC2 Fleet launches instances from all the Spot Instance pools that you specify.
If the allocation strategy is capacityOptimized
, EC2 Fleet launches instances from Spot Instance pools that are optimally chosen based on the available Spot Instance capacity.
Allowed Values : lowestPrice
| diversified
| capacityOptimized
| capacityOptimizedPrioritized
InstanceInterruptionBehavior
The behavior when a Spot Instance is interrupted.
virtual string InstanceInterruptionBehavior { get; }
Property Value
System.String
Remarks
InstancePoolsToUseCount
The number of Spot pools across which to allocate your target Spot capacity.
virtual Nullable<double> InstancePoolsToUseCount { get; }
Property Value
System.Nullable<System.Double>
Remarks
Supported only when Spot AllocationStrategy
is set to lowest-price
. EC2 Fleet selects the cheapest Spot pools and evenly allocates your target Spot capacity across the number of Spot pools that you specify.
Note that EC2 Fleet attempts to draw Spot Instances from the number of pools that you specify on a best effort basis. If a pool runs out of Spot capacity before fulfilling your target capacity, EC2 Fleet will continue to fulfill your request by drawing from the next cheapest pool. To ensure that your target capacity is met, you might receive Spot Instances from more than the number of pools that you specified. Similarly, if most of the pools have no Spot capacity, you might receive your full target capacity from fewer than the number of pools that you specified.
MaintenanceStrategies
The strategies for managing your Spot Instances that are at an elevated risk of being interrupted.
virtual object MaintenanceStrategies { get; }
Property Value
System.Object
Remarks
MaxTotalPrice
The maximum amount per hour for Spot Instances that you're willing to pay.
virtual string MaxTotalPrice { get; }
Property Value
System.String
Remarks
We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.
If you specify a maximum price, your Spot Instances will be interrupted more frequently than if you do not specify this parameter.
MinTargetCapacity
The minimum target capacity for Spot Instances in the fleet.
virtual Nullable<double> MinTargetCapacity { get; }
Property Value
System.Nullable<System.Double>
Remarks
If the minimum target capacity is not reached, the fleet launches no instances.
Supported only for fleets of type instant
.
At least one of the following must be specified: SingleAvailabilityZone
| SingleInstanceType
SingleAvailabilityZone
Indicates that the fleet launches all Spot Instances into a single Availability Zone.
virtual object SingleAvailabilityZone { get; }
Property Value
System.Object
Remarks
Supported only for fleets of type instant
.
SingleInstanceType
Indicates that the fleet uses a single instance type to launch all Spot Instances in the fleet.
virtual object SingleInstanceType { get; }
Property Value
System.Object
Remarks
Supported only for fleets of type instant
