Remarks

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:

Note: You must specify VCpuCount and MemoryMiB. All other attributes are optional. Any unspecified optional attribute is set to its default.

MaxSpotPriceAsPercentageOfOptimalOnDemandPrice

[Price protection] The price protection threshold for Spot Instances, as a percentage of an identified On-Demand price.

double? MaxSpotPriceAsPercentageOfOptimalOnDemandPrice { get; }

Property Value

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 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 you set DesiredCapacityType 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 Auto Scaling 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: - Automatic optimal price protection

double? OnDemandMaxPricePercentageOverLowestPrice { get; }

Property Value

double?

Remarks

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

To turn off price protection, specify a high value, such as 999999.

If you set DesiredCapacityType 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.

double? SpotMaxPricePercentageOverLowestPrice { get; }

Property Value

double?

Remarks

The identified Spot 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.
