.. py:method:: EC2.Client.get_instance_types_from_instance_requirements(**kwargs)

  

  Returns a list of instance types with the specified instance attributes. You can use the response to preview the instance types without launching instances. Note that the response does not consider capacity.

   

  When you specify multiple parameters, you get instance types that satisfy all of the specified parameters. If you specify multiple values for a parameter, you get instance types that satisfy any of the specified values.

      .. 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.

       

      Default: No minimum or maximum limits

      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``.

      - *(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 <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html>`__ in the *Amazon EC2 User Guide*.

       

      For current generation instance types, specify ``current``.

       

      For previous generation instance types, specify ``previous``.

      - *(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.

       

      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 <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_GetSpotPlacementScores.html>`__ and `GetInstanceTypesFromInstanceRequirements <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_GetInstanceTypesFromInstanceRequirements.html>`__.

       

      .. note::

        

        Only one of ``SpotMaxPricePercentageOverLowestPrice`` or ``MaxSpotPriceAsPercentageOfOptimalOnDemandPrice`` can be specified. If you don't specify either, Amazon EC2 will automatically apply optimal price protection to consistently select from a wide range of instance types. To indicate no price protection threshold for Spot Instances, meaning you want to consider all instance types that match your attributes, include one of these parameters and specify a high value, such as ``999999``.

        

       

      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 <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_GetSpotPlacementScores.html>`__ and `GetInstanceTypesFromInstanceRequirements <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_GetInstanceTypesFromInstanceRequirements.html>`__.

       

      .. 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``

      

    
    - **BareMetal** *(string) --*

    - **NetworkBandwidthGbps** *(dict) --* 

      The minimum and maximum amount of baseline network bandwidth, in gigabits per second (Gbps). For more information, see `Amazon EC2 instance network bandwidth <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-network-bandwidth.html>`__ in the *Amazon EC2 User Guide*.

       

      Default: No minimum or maximum limits

      

    
      - **Min** *(float) --* 

        The minimum amount of network bandwidth, in Gbps. To specify no minimum limit, omit this parameter.

        

      
      - **Max** *(float) --* 

        The maximum amount of network bandwidth, in Gbps. To specify no maximum limit, omit this parameter.

        

      
    
    - **AllowedInstanceTypes** *(list) --* 

      The instance types to apply your specified attributes against. All other instance types are ignored, even if they match your specified attributes.

       

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

       

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

       

      .. note::

        

        If you specify ``AllowedInstanceTypes``, you can't specify ``ExcludedInstanceTypes``.

        

       

      Default: All instance types

      

    
      - *(string) --* 

      
  
    - **MaxSpotPriceAsPercentageOfOptimalOnDemandPrice** *(integer) --* 

      [Price protection] The price protection threshold for Spot Instances, as a percentage of 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. If no current generation C, M, or R instance type matches your attributes, then the identified 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 price exceeds your specified threshold.

       

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

       

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

       

      .. note::

        

        Only one of ``SpotMaxPricePercentageOverLowestPrice`` or ``MaxSpotPriceAsPercentageOfOptimalOnDemandPrice`` can be specified. If you don't specify either, Amazon EC2 will automatically apply optimal price protection to consistently select from a wide range of instance types. To indicate no price protection threshold for Spot Instances, meaning you want to consider all instance types that match your attributes, include one of these parameters and specify a high value, such as ``999999``.

        

      

    
    - **BaselinePerformanceFactors** *(dict) --* 

      The baseline performance to consider, using an instance family as a baseline reference. The instance family establishes the lowest acceptable level of performance. Amazon EC2 uses this baseline to guide instance type selection, but there is no guarantee that the selected instance types will always exceed the baseline for every application. Currently, this parameter only supports CPU performance as a baseline performance factor. For more information, see `Performance protection <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-fleet-attribute-based-instance-type-selection.html#ec2fleet-abis-performance-protection>`__ in the *Amazon EC2 User Guide*.

      

    
      - **Cpu** *(dict) --* 

        The CPU performance to consider, using an instance family as the baseline reference.

        

      
        - **References** *(list) --* 

          Specify an instance family to use as the baseline reference for CPU performance. All instance types that match your specified attributes will be compared against the CPU performance of the referenced instance family, regardless of CPU manufacturer or architecture differences.

           

          .. note::

            

            Currently, only one instance family can be specified in the list.

            

          

        
          - *(dict) --* 

            Specify an instance family to use as the baseline reference for CPU performance. All instance types that match your specified attributes will be compared against the CPU performance of the referenced instance family, regardless of CPU manufacturer or architecture.

             

            .. note::

              

              Currently, only one instance family can be specified in the list.

              

            

          
            - **InstanceFamily** *(string) --* 

              The instance family to use as a baseline reference.

               

              .. note::

                

                Ensure that you specify the correct value for the instance family. The instance family is everything before the period ( ``.``) in the instance type name. For example, in the instance type ``c6i.large``, the instance family is ``c6i``, not ``c6``. For more information, see `Amazon EC2 instance type naming conventions <https://docs.aws.amazon.com/ec2/latest/instancetypes/instance-type-names.html>`__ in *Amazon EC2 Instance Types*.

                

               

              The following instance families are *not supported* for performance protection:

               

              
              * ``c1``
               
              * ``g3`` | ``g3s``
               
              * ``hpc7g``
               
              * ``m1`` | ``m2``
               
              * ``mac1`` | ``mac2`` | ``mac2-m1ultra`` | ``mac2-m2`` | ``mac2-m2pro``
               
              * ``p3dn`` | ``p4d`` | ``p5``
               
              * ``t1``
               
              * ``u-12tb1`` | ``u-18tb1`` | ``u-24tb1`` | ``u-3tb1`` | ``u-6tb1`` | ``u-9tb1`` | ``u7i-12tb`` | ``u7in-16tb`` | ``u7in-24tb`` | ``u7in-32tb``
              

               

              If you enable performance protection by specifying a supported instance family, the returned instance types will exclude the above unsupported instance families.

               

              If you specify an unsupported instance family as a value for baseline performance, the API returns an empty response for `GetInstanceTypesFromInstanceRequirements <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_GetInstanceTypesFromInstanceRequirements>`__ and an exception for `CreateFleet <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateFleet>`__, `RequestSpotFleet <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_RequestSpotFleet>`__, `ModifyFleet <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_ModifyFleet>`__, and `ModifySpotFleetRequest <https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_ModifySpotFleetRequest>`__.

              

            
          
      
      
    
    - **RequireEncryptionInTransit** *(boolean) --* 

      Specifies whether instance types must support encrypting in-transit traffic between instances. For more information, including the supported instance types, see `Encryption in transit <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/data-protection.html#encryption-transit>`__ in the *Amazon EC2 User Guide*.

       

      Default: ``false``
