AWSEC2OnDemandOptions

Objective-C

@interface AWSEC2OnDemandOptions

Swift

class AWSEC2OnDemandOptions

Describes the configuration of On-Demand Instances in an EC2 Fleet.

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

    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

    Declaration

    Objective-C

    @property (nonatomic) AWSEC2FleetOnDemandAllocationStrategy allocationStrategy;

    Swift

    var allocationStrategy: AWSEC2FleetOnDemandAllocationStrategy { get set }

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

    Supported only for fleets of type instant.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSEC2CapacityReservationOptions *_Nullable capacityReservationOptions;

    Swift

    var capacityReservationOptions: AWSEC2CapacityReservationOptions? { get set }

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

    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.

    Declaration

    Objective-C

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

    Swift

    var maxTotalPrice: String? { get set }

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

    Declaration

    Objective-C

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

    Swift

    var minTargetCapacity: NSNumber? { get set }

  • Indicates that the fleet launches all On-Demand 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 On-Demand 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 }
