The attributes for the instance types for a mixed instances policy. Amazon EC2 Auto Scaling uses your specified requirements to identify instance types. Then, it uses your On-Demand and Spot allocation strategies to launch instances from these instance types.
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 Auto Scaling 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.
You must specify VCpuCount
and MemoryMiB
. All other attributes are optional.
Any unspecified optional attribute is set to its default.
For more information, see Creating an Auto Scaling group using attribute-based instance type selection in the Amazon EC2 Auto Scaling User Guide. For help determining which instance types match your attributes before you apply them to your Auto Scaling group, see Preview instance types with specified attributes in the Amazon EC2 User Guide for Linux Instances.

You can use strings with one or more wild cards, represented by an asterisk (
For example, if you specify
If you specify Default: All instance types |
|
BareMetal | Amazon.AutoScaling.BareMetal |
Gets and sets the property BareMetal. Indicates whether bare metal instance types are included, excluded, or required.
Default: |
|
BaselineEbsBandwidthMbps | Amazon.AutoScaling.Model.BaselineEbsBandwidthMbpsRequest |
Gets and sets the property BaselineEbsBandwidthMbps. The minimum and maximum baseline bandwidth performance for an instance type, in Mbps. For more information, see Amazon EBS–optimized instances in the Amazon EC2 User Guide for Linux Instances. Default: No minimum or maximum limits |
|
BurstablePerformance | Amazon.AutoScaling.BurstablePerformance |
Gets and sets the property BurstablePerformance. Indicates whether burstable performance instance types are included, excluded, or required. For more information, see Burstable performance instances in the Amazon EC2 User Guide for Linux Instances.
Default: |
|
CpuManufacturers | System.Collections.Generic.List<System.String> |
Gets and sets the property CpuManufacturers. Lists which specific CPU manufacturers to include.
Don't confuse the CPU hardware manufacturer with the CPU hardware 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 |
|
ExcludedInstanceTypes | System.Collections.Generic.List<System.String> |
Gets and sets the property ExcludedInstanceTypes.
The instance types to exclude. You can use strings with one or more wild cards, represented
by an asterisk (
For example, if you specify
If you specify Default: No excluded instance types |
|
InstanceGenerations | System.Collections.Generic.List<System.String> |
Gets and sets the property InstanceGenerations. Indicates whether current or previous generation instance types are included.
Default: Any current or previous generation |
|
LocalStorage | Amazon.AutoScaling.LocalStorage |

Default: |
|
LocalStorageTypes | System.Collections.Generic.List<System.String> |
Gets and sets the property LocalStorageTypes. Indicates the type of local storage that is required.
Default: Any local storage type |
|
MaxSpotPriceAsPercentageOfOptimalOnDemandPrice | System.Int32 |
Gets and sets the property MaxSpotPriceAsPercentageOfOptimalOnDemandPrice. [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 either the lowest priced current generation instance types or, failing that, the lowest priced previous generation instance types that match your attributes. When Amazon EC2 Auto Scaling selects instance types with your attributes, we will exclude instance types whose price exceeds your specified threshold. The parameter accepts an integer, which Amazon EC2 Auto Scaling interprets as a percentage.

If no current generation C, M, or R instance type matches your attributes, then the identified price is from either the lowest priced current generation instance types or, failing that, the lowest priced previous generation instance types that match your attributes. When Amazon EC2 Auto Scaling selects instance types with your attributes, we will exclude instance types whose price exceeds your specified threshold. The parameter accepts an integer, which Amazon EC2 Auto Scaling interprets as a percentage.
