To scale up your EC2 Fleet, increase its target capacity. The EC2 Fleet launches the
additional Spot Instances according to the allocation strategy for the EC2 Fleet request.
If the allocation strategy is
lowest-price, the EC2 Fleet launches instances
using the Spot Instance pool with the lowest price. If the allocation strategy is
diversified, the EC2 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 EC2 Fleet, decrease its target capacity. First, the EC2 Fleet cancels
any open requests that exceed the new target capacity. You can request that the EC2
Fleet terminate Spot Instances until the size of the fleet no longer exceeds the new
target capacity. If the allocation strategy is
lowest-price, the EC2
Fleet terminates the instances with the highest price per unit. If the allocation
capacity-optimized, the EC2 Fleet terminates the instances
in the Spot Instance pools that have the least available Spot Instance capacity. If
the allocation strategy is
diversified, the EC2 Fleet terminates instances
across the Spot Instance pools. Alternatively, you can request that the EC2 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 EC2 Fleet for now, but will use it again later, you can set the target capacity to 0.
