To scale up your Spot Fleet, increase its target capacity. The Spot Fleet launches
the additional Spot Instances according to the allocation strategy for the Spot Fleet
request. If the allocation strategy is
lowestPrice, the Spot Fleet launches
instances using the Spot Instance pool with the lowest price. If the allocation strategy
diversified, the Spot Fleet distributes the instances across the Spot
Instance pools. If the allocation strategy is
Fleet launches instances from Spot Instance pools with optimal capacity for the number
of instances that are launching.
To scale down your Spot Fleet, decrease its target capacity. First, the Spot Fleet
cancels any open requests that exceed the new target capacity. You can request that
the Spot Fleet terminate Spot Instances until the size of the fleet no longer exceeds
the new target capacity. If the allocation strategy is
Spot Fleet terminates the instances with the highest price per unit. If the allocation
capacityOptimized, the Spot Fleet terminates the instances
in the Spot Instance pools that have the least available Spot Instance capacity. If
the allocation strategy is
diversified, the Spot Fleet terminates instances
across the Spot Instance pools. Alternatively, you can request that the Spot Fleet
keep the fleet at its current size, but not replace any Spot Instances that are interrupted
or that you terminate manually.
If you are finished with your Spot Fleet for now, but will use it again later, you can set the target capacity to 0.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginModifySpotFleetRequest and EndModifySpotFleetRequest.
