Parameters:

• InstanceTypes (list) –

  The instance types. We recommend that you specify at least three instance types. If you specify one or two instance types, or specify variations of a single instance type (for example, an m3.xlarge with and without instance storage), the returned placement score will always be low.

  If you specify InstanceTypes, you can’t specify InstanceRequirementsWithMetadata.

  • (string) –

• TargetCapacity (integer) –

  [REQUIRED]

  The target capacity.

• TargetCapacityUnitType (string) – The unit for the target capacity.

• SingleAvailabilityZone (boolean) –

  Specify true so that the response returns a list of scored Availability Zones. Otherwise, the response returns a list of scored Regions.

  A list of scored Availability Zones is useful if you want to launch all of your Spot capacity into a single Availability Zone.

• RegionNames (list) –

  The Regions used to narrow down the list of Regions to be scored. Enter the Region code, for example, us-east-1.

  • (string) –

• InstanceRequirementsWithMetadata (dict) –

  The attributes for the instance types. When you specify instance attributes, Amazon EC2 will identify instance types with those attributes.

  If you specify InstanceRequirementsWithMetadata, you can’t specify InstanceTypes.

  • ArchitectureTypes (list) –

    The architecture type.

    • (string) –

  • VirtualizationTypes (list) –

    The virtualization type.

    • (string) –

  • InstanceRequirements (dict) –

    The attributes for the instance types. When you specify instance attributes, Amazon EC2 will identify instance types with those attributes.

    • VCpuCount (dict) – [REQUIRED]

      The minimum and maximum number of vCPUs.

      • Min (integer) – [REQUIRED]

        The minimum number of vCPUs. To specify no minimum limit, specify 0.

        The maximum number of vCPUs. To specify no maximum limit, omit this parameter.

    • MemoryMiB (dict) – [REQUIRED]

      The minimum and maximum amount of memory, in MiB.

      • Min (integer) – [REQUIRED]

        The minimum amount of memory, in MiB. To specify no minimum limit, specify 0.

        The maximum amount of memory, in MiB. To specify no maximum limit, omit this parameter.

    • CpuManufacturers (list) –

      The CPU manufacturers to include.

      • For instance types with Intel CPUs, specify intel.

      • For instance types with AMD CPUs, specify amd.

      • For instance types with Amazon Web Services CPUs, specify amazon-web-services.

      Note

      Don’t confuse the CPU manufacturer with the CPU architecture. Instances will be launched with a compatible CPU architecture based on the Amazon Machine Image (AMI) that you specify in your launch template.

      Default: Any manufacturer

      • (string) –

    • MemoryGiBPerVCpu (dict) –

      The minimum and maximum amount of memory per vCPU, in GiB.

        The maximum amount of memory per vCPU, in GiB. To specify no maximum limit, omit this parameter.

    • ExcludedInstanceTypes (list) –

      The instance types to exclude.

      You can use strings with one or more wild cards, represented by an asterisk ( *), to exclude an instance family, type, size, or generation. The following are examples: m5.8xlarge, c5*.*, m5a.*, r*, *3*.

      For example, if you specify c5*,Amazon EC2 will exclude the entire C5 instance family, which includes all C5a and C5n instance types. If you specify m5a.*, Amazon EC2 will exclude all the M5a instance types, but not the M5n instance types.

      Note

      If you specify ExcludedInstanceTypes, you can’t specify AllowedInstanceTypes.

      Default: No excluded instance types

      • (string) –

    • InstanceGenerations (list) –

      Indicates whether current or previous generation instance types are included. The current generation instance types are recommended for use. Current generation instance types are typically the latest two to three generations in each instance family. For more information, see Instance types in the Amazon EC2 User Guide.

      For current generation instance types, specify current.

      For previous generation instance types, specify previous.

      Default: Current and previous generation instance types

      • (string) –

    • SpotMaxPricePercentageOverLowestPrice (integer) –

      [Price protection] The price protection threshold for Spot Instances, as a percentage higher than an identified Spot price. The identified Spot price is the Spot price of the lowest priced current generation C, M, or R instance type with your specified attributes. If no current generation C, M, or R instance type matches your attributes, then the identified Spot price is from the lowest priced current generation instance types, and failing that, from the lowest priced previous generation instance types that match your attributes. When Amazon EC2 selects instance types with your attributes, it will exclude instance types whose Spot price exceeds your specified threshold.

      The parameter accepts an integer, which Amazon EC2 interprets as a percentage.

      To indicate no price protection threshold, specify a high value, such as 999999.

      If you set TargetCapacityUnitType to vcpu or memory-mib, the price protection threshold is applied based on the per-vCPU or per-memory price instead of the per-instance price.

      This parameter is not supported for GetSpotPlacementScores and GetInstanceTypesFromInstanceRequirements.

      Note

      Only one of SpotMaxPricePercentageOverLowestPrice or MaxSpotPriceAsPercentageOfOptimalOnDemandPrice can be specified. If you don’t specify either, then SpotMaxPricePercentageOverLowestPrice is used and the value for that parameter defaults to 100.

      Default: 100

    • OnDemandMaxPricePercentageOverLowestPrice (integer) –

      [Price protection] The price protection threshold for On-Demand Instances, as a percentage higher than an identified On-Demand price. The identified On-Demand price is the price of the lowest priced current generation C, M, or R instance type with your specified attributes. When Amazon EC2 selects instance types with your attributes, it will exclude instance types whose price exceeds your specified threshold.

      The parameter accepts an integer, which Amazon EC2 interprets as a percentage.

      To indicate no price protection threshold, specify a high value, such as 999999.

      This parameter is not supported for GetSpotPlacementScores and GetInstanceTypesFromInstanceRequirements.

      Note

      If you set TargetCapacityUnitType to vcpu or memory-mib, the price protection threshold is applied based on the per-vCPU or per-memory price instead of the per-instance price.

      Default: 20

Response Structure

• (dict) –

  • SpotPlacementScores (list) –

    The Spot placement score for the top 10 Regions or Availability Zones, scored on a scale from 1 to 10. Each score reflects how likely it is that each Region or Availability Zone will succeed at fulfilling the specified target capacity

at the time of the Spot placement score request. A score of 10 means that your Spot capacity request is highly likely to succeed in that Region or Availability Zone.

If you request a Spot placement score for Regions, a high score assumes that your fleet request will be configured to use all Availability Zones and the capacity-optimized allocation strategy. If you request a Spot placement score for Availability Zones, a high score assumes that your fleet request will be configured to use a single Availability Zone and the capacity-optimized allocation strategy.

Different Regions or Availability Zones might return the same score.

Note

The Spot placement score serves as a recommendation only. No score guarantees that your Spot request will be fully or partially fulfilled.

• (dict) –

  The Spot placement score for this Region or Availability Zone. The score is calculated based on the assumption that the capacity-optimized allocation strategy is used and that all of the Availability Zones in the Region can be used.

  • Region (string) –

    The Region.

  • AvailabilityZoneId (string) –

    The Availability Zone.

  • Score (integer) –

    The placement score, on a scale from 1 to 10. A score of 10 indicates that your Spot request is highly likely to succeed in this Region or Availability Zone. A score of 1 indicates that your Spot request is not likely to succeed.
