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.
We strongly discourage using the RequestSpotFleet API because it is a legacy
API with no planned investment. For options for requesting Spot Instances, see
Which
is the best Spot request method to use? in the
Amazon EC2 User Guide.
