	// The number of capacity units provided by the specified instance type in terms of virtual CPUs, memory, storage, throughput, or other relative performance characteristic.
	//
	// When a Spot or On-Demand Instance is provisioned, the
	// capacity units count toward the desired capacity. Amazon EC2 Auto Scaling provisions instances until the desired
	// capacity is totally fulfilled, even if this results in an overage. Value must be in the range of 1 to 999.
	//
	// For example, If there are 2 units remaining to fulfill capacity, and Amazon EC2 Auto Scaling can only provision
	// an instance with a WeightedCapacity of 5 units, the instance is provisioned, and the desired capacity is exceeded
	// by 3 units.
