// Creates a Spot Fleet request. The Spot Fleet request specifies the total target
// capacity and the On-Demand target capacity. Amazon EC2 calculates the difference
// between the total capacity and On-Demand capacity, and launches the difference
// as Spot capacity. You can submit a single request that includes multiple launch
// specifications that vary by instance type, AMI, Availability Zone, or subnet. By
// default, the Spot Fleet requests Spot Instances in the Spot Instance 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. 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. You can
// specify tags for the Spot Fleet request and instances launched by the fleet. You
// cannot tag other resource types in a Spot Fleet request because only the
// spot-fleet-request and instance resource types are supported. For more
// information, see Spot Fleet requests
// (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-fleet-requests.html)
// in the Amazon EC2 User Guide for Linux Instances.
