InstanceRequirementsRequest
The attributes for the instance types. 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:
AllowedInstanceTypes- The instance types to include in the list. All other instance types are ignored, even if they match your specified attributes.ExcludedInstanceTypes- The instance types to exclude from the list, even if they match your specified attributes.
If you specify InstanceRequirements, you can't specify InstanceType.
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 Amazon Web Services CloudFormation resource, you can't specify InstanceRequirements.
For more information, see Attribute-based instance type selection for EC2 Fleet, Attribute-based instance type selection for Spot Fleet, and Spot placement score in the Amazon EC2 User Guide.
Types
Properties
The minimum and maximum number of accelerators (GPUs, FPGAs, or Amazon Web Services Inferentia chips) on an instance.
Indicates whether instance types must have accelerators by specific manufacturers.
The accelerators that must be on the instance type.
The minimum and maximum amount of total accelerator memory, in MiB.
The accelerator types that must be on the instance type.
The instance types to apply your specified attributes against. All other instance types are ignored, even if they match your specified attributes.
The minimum and maximum baseline bandwidth to Amazon EBS, in Mbps. For more information, see Amazon EBS–optimized instances in the Amazon EC2 User Guide.
Indicates whether burstable performance T instance types are included, excluded, or required. For more information, see Burstable performance instances.
The CPU manufacturers to include.
The instance types to exclude.
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.
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.
The type of local storage that is required.
[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 minimum and maximum amount of memory per vCPU, in GiB.
The minimum and maximum amount of memory, in MiB.
The minimum and maximum amount of baseline network bandwidth, in gigabits per second (Gbps). For more information, see Amazon EC2 instance network bandwidth in the Amazon EC2 User Guide.
The minimum and maximum number of network interfaces.
[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.
Indicates whether instance types must support hibernation for On-Demand Instances.
[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 minimum and maximum amount of total local storage, in GB.
The minimum and maximum number of vCPUs.
