Parameters
value
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. When Amazon EC2 Auto Scaling selects instance types with your attributes, we will exclude instance types whose price is higher than your threshold. 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. Default is 20. If you set target_capacity_unit_type 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.
