Properties

AllocationStrategy

Indicates how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the EC2 Fleet.

public string? AllocationStrategy { get; set; }
Property Value

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

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

InstanceInterruptionBehavior

The behavior when a Spot Instance is interrupted.

public string? InstanceInterruptionBehavior { get; set; }
Property Value

string

Remarks

Default: terminate

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

InstancePoolsToUseCount

The number of Spot pools across which to allocate your target Spot capacity.

public double? InstancePoolsToUseCount { get; set; }
Property Value

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.

public object? MaintenanceStrategies { get; set; }
Property Value

object

Remarks

Type union: either IResolvable or CfnEC2Fleet.IMaintenanceStrategiesProperty

MaxTotalPrice

The maximum amount per hour for Spot Instances that you're willing to pay.

public string? MaxTotalPrice { get; set; }
Property Value

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. > If your fleet includes T instances that are configured as <code>unlimited</code> , and if their average CPU usage exceeds the baseline utilization, you will incur a charge for surplus credits. The <code>MaxTotalPrice</code> does not account for surplus credits, and, if you use surplus credits, your final cost might be higher than what you specified for <code>MaxTotalPrice</code> . For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/burstable-performance-instances-unlimited-mode-concepts.html#unlimited-mode-surplus-credits">Surplus credits can incur charges</a> in the <em>Amazon EC2 User Guide</em> .

MinTargetCapacity

The minimum target capacity for Spot Instances in the fleet.

public double? MinTargetCapacity { get; set; }
Property Value

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

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

SingleAvailabilityZone

Indicates that the fleet launches all Spot Instances into a single Availability Zone.

public object? SingleAvailabilityZone { get; set; }
Property Value

object

Remarks

Supported only for fleets of type instant .

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

Type union: either bool or IResolvable

SingleInstanceType

Indicates that the fleet uses a single instance type to launch all Spot Instances in the fleet.

public object? SingleInstanceType { get; set; }
Property Value

object

Remarks

Supported only for fleets of type instant .
