public enum SpotAllocationStrategy
extends Enum<SpotAllocationStrategy>

Indicates how to allocate instance types to fulfill Spot capacity.

Enum Constant Summary

Enum Constants

Enum Constant and Description
CAPACITY_OPTIMIZED The Auto Scaling group launches instances using Spot pools that are optimally chosen based on the available Spot capacity.
CAPACITY_OPTIMIZED_PRIORITIZED When you use this strategy, you need to set the order of instance types in the list of launch template overrides from highest to lowest priority (from first to last in the list).
LOWEST_PRICE The Auto Scaling group launches instances using the Spot pools with the lowest price, and evenly allocates your instances across the number of Spot pools that you specify.

Method Summary

Modifier and Type	Method and Description
static SpotAllocationStrategy	valueOf(String name) Returns the enum constant of this type with the specified name.
static SpotAllocationStrategy[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

LOWEST_PRICE

@Stability(value=Stable)
public static final SpotAllocationStrategy LOWEST_PRICE

The Auto Scaling group launches instances using the Spot pools with the lowest price, and evenly allocates your instances across the number of Spot pools that you specify.

CAPACITY_OPTIMIZED

@Stability(value=Stable)
public static final SpotAllocationStrategy CAPACITY_OPTIMIZED

The Auto Scaling group launches instances using Spot pools that are optimally chosen based on the available Spot capacity.

Recommended.

CAPACITY_OPTIMIZED_PRIORITIZED

@Stability(value=Stable)
public static final SpotAllocationStrategy CAPACITY_OPTIMIZED_PRIORITIZED

When you use this strategy, you need to set the order of instance types in the list of launch template overrides from highest to lowest priority (from first to last in the list).

Amazon EC2 Auto Scaling honors the instance type priorities on a best-effort basis but optimizes for capacity first.

Method Detail

values

public static SpotAllocationStrategy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SpotAllocationStrategy c : SpotAllocationStrategy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SpotAllocationStrategy valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
