AWSEC2SpotOptions

Objective-C

@interface AWSEC2SpotOptions

Swift

class AWSEC2SpotOptions

Describes the configuration of Spot Instances in an EC2 Fleet.

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

    If the allocation strategy is lowest-price, 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 of the Spot Instance pools that you specify.

    If the allocation strategy is capacity-optimized, EC2 Fleet launches instances from Spot Instance pools with optimal capacity for the number of instances that are launching.

    Declaration

    Objective-C

    @property (nonatomic) AWSEC2SpotAllocationStrategy allocationStrategy;

    Swift

    var allocationStrategy: AWSEC2SpotAllocationStrategy { get set }

  • The behavior when a Spot Instance is interrupted. The default is terminate.

    Declaration

    Objective-C

    @property (nonatomic) AWSEC2SpotInstanceInterruptionBehavior instanceInterruptionBehavior;

    Swift

    var instanceInterruptionBehavior: AWSEC2SpotInstanceInterruptionBehavior { get set }

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

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable instancePoolsToUseCount;

    Swift

    var instancePoolsToUseCount: NSNumber? { get set }

  • The strategies for managing your workloads on your Spot Instances that will be interrupted. Currently only the capacity rebalance strategy is available.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2FleetSpotMaintenanceStrategies *_Nullable maintenanceStrategies;

    Swift

    var maintenanceStrategies: AWSEC2FleetSpotMaintenanceStrategies? { get set }

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

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable maxTotalPrice;

    Swift

    var maxTotalPrice: String? { get set }

  • The minimum target capacity for Spot Instances in the fleet. If the minimum target capacity is not reached, the fleet launches no instances.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable minTargetCapacity;

    Swift

    var minTargetCapacity: NSNumber? { get set }

  • Indicates that the fleet launches all Spot Instances into a single Availability Zone. Supported only for fleets of type instant.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable singleAvailabilityZone;

    Swift

    var singleAvailabilityZone: NSNumber? { get set }

  • Indicates that the fleet uses a single instance type to launch all Spot Instances in the fleet. Supported only for fleets of type instant.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable singleInstanceType;

    Swift

    var singleInstanceType: NSNumber? { get set }
