get-spot-placement-scores¶

Description¶

Calculates the Spot placement score for a Region or Availability Zone based on the specified target capacity and compute requirements.

You can specify your compute requirements either by using InstanceRequirementsWithMetadata and letting Amazon EC2 choose the optimal instance types to fulfill your Spot request, or you can specify the instance types by using InstanceTypes .

For more information, see Spot placement score in the Amazon EC2 User Guide.

Options¶

--instance-types (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)

Syntax:

"string" "string" ...

--target-capacity (integer)

The target capacity.

--target-capacity-unit-type (string)

The unit for the target capacity.

Default: units (translates to number of instances)

Possible values:

vcpu

memory-mib

units

--single-availability-zone | --no-single-availability-zone (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.

--region-names (list)

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

(string)

Syntax:

"string" "string" ...

The price protection threshold for Spot Instance. This is the maximum you’ll pay for an Spot Instance, expressed as a percentage above the cheapest 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.

--dry-run | --no-dry-run (boolean)

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To calculate the Spot placement score for specified requirements

The following get-spot-placement-scores example first generates a list of all of the possible parameters that can be specified for the Spot placement score configuration using the --generate-cli-skeleton parameter, and saves the list to a JSON file. Then, the JSON file is used to configure the requirements to use to calculate the Spot placement score.

To generate all possible parameters that can be specified for the Spot placement score configuration, and save the output directly to a JSON file.

Output¶

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.

(structure)

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.

NextToken -> (string)

The token for the next set of results.
