/**
 * Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#requestSpotFleet(RequestSpotFleetRequest) RequestSpotFleet operation}.
 * <p>
 * Creates a Spot fleet request.
 * </p>
 * <p>
 * You can submit a single request that includes multiple launch
 * specifications that vary by instance type, AMI, Availability Zone, or
 * subnet.
 * </p>
 * <p>
 * By default, the Spot fleet requests Spot instances in the Spot pool
 * where the price per unit is the lowest. Each launch specification can
 * include its own instance weighting that reflects the value of the
 * instance type to your application workload.
 * </p>
 * <p>
 * Alternatively, you can specify that the Spot fleet distribute the
 * target capacity across the Spot pools included in its launch
 * specifications. By ensuring that the Spot instances in your Spot fleet
 * are in different Spot pools, you can improve the availability of your
 * fleet.
 * </p>
