InstanceRequirementsRequest - Amazon Elastic Compute Cloud
ContentsSee Also

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.

Note

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 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.

AllowedInstanceType.N

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

Type: Array of strings

Array Members: Minimum number of 0 items. Maximum number of 400 items.

Length Constraints: Minimum length of 1. Maximum length of 30.

Pattern: [a-zA-Z0-9\.\*\-]+

Required: No

BareMetal

Default: No minimum or maximum limits

Type: BaselineEbsBandwidthMbpsRequest object

Required: No

BaselinePerformanceFactors

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 in the Amazon EC2 User Guide.

Type: BaselinePerformanceFactorsRequest object

Required: No

  • For instance types with AMD CPUs, specify amd.

  • For instance types with AWS CPUs, specify 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

Type: Array of strings

Valid Values: intel | amd | amazon-web-services | apple

Required: No

ExcludedInstanceType.N

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

Array Members: Minimum number of 0 items. Maximum number of 400 items.

Length Constraints: Minimum length of 1. Maximum length of 30.

Pattern: [a-zA-Z0-9\.\*\-]+

InstanceGeneration.N

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.
