Method Detail

allocationStrategy

public final SpotAllocationStrategy allocationStrategy()

The strategy that determines how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the EC2 Fleet launch configuration. For more information, see Allocation strategies for Spot Instances in the Amazon EC2 User Guide.

price-capacity-optimized (recommended)

EC2 Fleet identifies the pools with the highest capacity availability for the number of instances that are launching. This means that we will request Spot Instances from the pools that we believe have the lowest chance of interruption in the near term. EC2 Fleet then requests Spot Instances from the lowest priced of these pools.

capacity-optimized

EC2 Fleet identifies the pools with the highest capacity availability for the number of instances that are launching. This means that we will request Spot Instances from the pools that we believe have the lowest chance of interruption in the near term. To give certain instance types a higher chance of launching first, use capacity-optimized-prioritized. Set a priority for each instance type by using the Priority parameter for LaunchTemplateOverrides. You can assign the same priority to different LaunchTemplateOverrides. EC2 implements the priorities on a best-effort basis, but optimizes for capacity first. capacity-optimized-prioritized is supported only if your EC2 Fleet uses a launch template. Note that if the On-Demand AllocationStrategy is set to prioritized, the same priority is applied when fulfilling On-Demand capacity.

diversified

EC2 Fleet requests instances from all of the Spot Instance pools that you specify.

lowest-price

EC2 Fleet requests instances from the lowest priced Spot Instance pool that has available capacity. If the lowest priced pool doesn't have available capacity, the Spot Instances come from the next lowest priced pool that has available capacity. If a pool runs out of capacity before fulfilling your desired capacity, EC2 Fleet will continue to fulfill your request by drawing from the next lowest priced pool. To ensure that your desired capacity is met, you might receive Spot Instances from several pools. Because this strategy only considers instance price and not capacity availability, it might lead to high interruption rates.

Default: lowest-price

If the service returns an enum value that is not available in the current SDK version, allocationStrategy will return SpotAllocationStrategy.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from allocationStrategyAsString().

Returns:

The strategy that determines how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the EC2 Fleet launch configuration. For more information, see Allocation strategies for Spot Instances in the Amazon EC2 User Guide.

instancePoolsToUseCount

public final Integer instancePoolsToUseCount()

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

Returns:

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