class AWSAutoScalingInstanceRequirements

When you specify multiple parameters, you get instance types that satisfy all of the specified parameters. If you specify multiple values for a parameter, you get instance types that satisfy any of the specified values.

Represents requirements for the types of instances that can be launched. You must specify VCpuCount and MemoryMiB, but all other parameters are optional. For more information, see Creating an Auto Scaling group using attribute-based instance type selection in the Amazon EC2 Auto Scaling User Guide.

  • The price protection threshold for On-Demand Instances. This is the maximum you’ll pay for an On-Demand Instance, expressed as a percentage higher than the cheapest M, C, or R instance type with your specified attributes.

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.
