SpotFleetAllocationStrategy

The Spot Fleet allocation strategy. This parameter can be used only when Spot Fleet is enabled by setting SpotFleetMaxPrice.

| Default value | lowestPrice | | Allowed values | lowestPrice, diversified, capacityOptimized |

Use Cases

• Using lowestPrice (default) to minimize costs by selecting the cheapest available Spot pools
• Switching to capacityOptimized for workloads that need higher availability by selecting pools with the most available capacity, reducing the chance of interruption
• Using diversified to spread instances across multiple Spot pools, reducing the impact of a single pool being reclaimed

Additional Information

The three strategies behave as follows:

• lowestPrice -- Spot instances are launched from the pool with the lowest price. This maximizes cost savings but may lead to higher interruption rates if the cheapest pool runs low on capacity.
• diversified -- Spot instances are distributed across all available pools. This reduces the risk of all instances being interrupted simultaneously.
• capacityOptimized -- Spot instances are launched from pools with the most available capacity. This is the best choice for workloads that have a high cost of interruption.

This parameter only takes effect when Spot Fleet is enabled via SpotFleetMaxPrice.
