You can now scale the target capacity of a fleet of Spot instances up or down using the ModifySpotFleetRequest API. Previously, you could not modify the fleet’s target capacity after submitting a Spot fleet request.

The new ModifySpotFleetRequest API is available in all regions where Spot instances are currently supported. To get started, download the AWS SDKs or Command-Line Tools to provision and scale a Spot fleet.

To learn more, visit the Spot Fleet Requests section in the Amazon EC2 User Guide.
