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 .
[REQUIRED]
The target capacity.
The unit for the target capacity.
Default: units (translates to number of instances)
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.
The Regions used to narrow down the list of Regions to be scored. Enter the Region code, for example, us-east-1 .
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 .
The architecture type.
The virtualization type.
The attributes for the instance types. When you specify instance attributes, Amazon EC2 will identify instance types with those attributes.
The minimum and maximum number of vCPUs.

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

The maximum amount of memory, in MiB. To specify no maximum limit, omit this parameter.
The CPU manufacturers to include.
intel .amd .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
The minimum and maximum amount of memory per vCPU, in GiB.
Default: No minimum or maximum limits
The minimum amount of memory per vCPU, in GiB. To specify no minimum limit, omit this parameter.
The maximum amount of memory per vCPU, in GiB. To specify no maximum limit, omit this parameter.
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
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
The price protection threshold for Spot Instance. This is the maximum you’ll pay for an Spot Instance, expressed as a percentage above the least expensive current generation M, C, or R instance type with your specified attributes. When Amazon EC2 selects instance types with your attributes, it excludes instance types priced above your threshold.
The parameter accepts an integer, which Amazon EC2 interprets as a percentage.
To turn off price protection, 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: 100
The price protection threshold for On-Demand Instances. This is the maximum you’ll pay for an On-Demand Instance, expressed as a percentage above the least expensive current generation M, C, or R instance type with your specified attributes. When Amazon EC2 selects instance types with your attributes, it excludes instance types priced above your threshold.
The parameter accepts an integer, which Amazon EC2 interprets as a percentage.
To turn off price protection, 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
Indicates whether bare metal instance types must be included, excluded, or required.
included .required .excluded .Default: excluded
Indicates whether burstable performance T instance types are included, excluded, or required. For more information, see Burstable performance instances.

Indicates whether instance types must support hibernation for On-Demand Instances.
This parameter is not supported for GetSpotPlacementScores.
Default: false
The minimum and maximum number of network interfaces.
Default: No minimum or maximum limits
The minimum number of network interfaces. To specify no minimum limit, omit this parameter.
The maximum number of network interfaces. To specify no maximum limit, omit this parameter.
Indicates whether instance types with instance store volumes are included, excluded, or required. For more information, Amazon EC2 instance store in the Amazon EC2 User Guide .
included .required .excluded .Default: included
The type of local storage that is required.
hdd .ssd .Default: hdd and ssd
The minimum and maximum amount of total local storage, in GB.
Default: No minimum or maximum limits
The minimum amount of total local storage, in GB. To specify no minimum limit, omit this parameter.

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.
