**To create an EC2 Fleet that launches Spot Instances as the default purchasing model**
2+
3+
This example creates an EC2 Fleet using the minimum parameters required to launch a fleet: a launch template, target capacity, and default purchasing model. The launch template is identified by its launch template ID and version number. The target capacity for the fleet is 2 instances, and the default purchasing model is ``spot``, which results in the fleet launching 2 Spot Instances.
4+
5+
When you create an EC2 Fleet, use a JSON file to specify information about the instances to launch.

aws ec2 create-fleet --cli-input-json file://file_name.json

**To create an EC2 Fleet that launches On-Demand Instances as the primary capacity**
72+
73+
This example creates an EC2 Fleet that specifies the total target capacity of 2 instances for the fleet, and a target capacity of 1 On-Demand Instance. The default purchasing model is ``spot``. The fleet launches 1 On-Demand Instance as specified, but needs to launch one more instance to fulfil the total target capacity. The purchasing model for the difference is calculated as ``TotalTargetCapacity`` – ``OnDemandTargetCapacity`` = ``DefaultTargetCapacityType``, which results in the fleet launching 1 Spot Instance.

**To create an EC2 Fleet that launches Spot Instances using the lowest-price allocation strategy**
108+
109+
If the allocation strategy for Spot Instances is not specified, the default allocation strategy, which is ``lowest-price``, is used. This example creates an EC2 Fleet using the ``lowest-price`` allocation strategy. The three launch specifications, which override the launch template, have different instance types but the same weighted capacity and subnet. The total target capacity is 2 instances and the default purchasing model is ``spot``. The EC2 Fleet launches 2 Spot Instances using the instance type of the launch specification with the lowest price.
