Implements CfnLaunchTemplate.IInstanceRequirementsPropertyRemarks
When you specify instance attributes, Amazon EC2 will identify instance types with these attributes.
You must specify VCpuCount and MemoryMiB . All other attributes are optional. Any unspecified optional attribute is set to its default.
When you specify multiple attributes, you get instance types that satisfy all of the specified attributes. If you specify multiple values for an attribute, you get instance types that satisfy any of the specified values.
To limit the list of instance types from which Amazon EC2 can identify matching instance types, you can use one of the following parameters, but not both in the same request:
If you specify <code>InstanceRequirements</code> , you can't specify <code>InstanceType</code> .
Attribute-based instance type selection is only supported when using Auto Scaling groups, EC2 Fleet, and Spot Fleet to launch instances. If you plan to use the launch template in the launch instance wizard , or with the RunInstances API or AWS::EC2::Instance AWS CloudFormation resource, you can't specify InstanceRequirements .
For more information, see Specify attributes for instance type selection for EC2 Fleet or Spot Fleet and Spot placement score in the Amazon EC2 User Guide .

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

public string[] ExcludedInstanceTypes { get; set; }Property Value
System.String[]

MaxSpotPriceAsPercentageOfOptimalOnDemandPrice
[Price protection] The price protection threshold for Spot Instances, as a percentage of an identified On-Demand price.
public Nullable<double> MaxSpotPriceAsPercentageOfOptimalOnDemandPrice { get; set; }Property Value
System.Nullable<System.Double>
Remarks
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.
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 .
MemoryGiBPerVCpu

Remarks
OnDemandMaxPricePercentageOverLowestPrice
[Price protection] The price protection threshold for On-Demand Instances, as a percentage higher than an identified On-Demand price.
public Nullable<double> OnDemandMaxPricePercentageOverLowestPrice { get; set; }Property Value
System.Nullable<System.Double>
Remarks
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 turn off price protection, specify a high value, such as 999999 .
This parameter is not supported for GetSpotPlacementScores and GetInstanceTypesFromInstanceRequirements .
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
RequireHibernateSupport
Indicates whether instance types must support hibernation for On-Demand Instances.
public object RequireHibernateSupport { get; set; }Property Value
System.Object
Remarks
This parameter is not supported for GetSpotPlacementScores .

[Price protection] The price protection threshold for Spot Instances, as a percentage higher than an identified Spot price.
public Nullable<double> SpotMaxPricePercentageOverLowestPrice { get; set; }Property Value
System.Nullable<System.Double>
Remarks
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.

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 .
