Parameters
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 the lowest priced current generation instance types, and failing that, from the lowest priced previous generation instance types that match your attributes. When Amazon EC2 selects instance types with your attributes, it will exclude instance types whose price exceeds your specified threshold. The parameter accepts an integer, which Amazon EC2 interprets as a percentage. If you set TargetCapacityUnitType 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.
Only one of
SpotMaxPricePercentageOverLowestPriceorMaxSpotPriceAsPercentageOfOptimalOnDemandPricecan be specified. If you don't specify either, Amazon EC2 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 as999999.
