class Aws::GameLift::Types::InstanceDefinition

**This data type is used with the GameLift FleetIQ and game server groups.**

An allowed instance type for a GameServerGroup. All game server groups must have at least two instance types defined for it. GameLift FleetIQ periodically evaluates each defined instance type for viability. It then updates the Auto Scaling group with the list of viable instance types.

@note When making an API call, you may pass InstanceDefinition

data as a hash:

      weighted_capacity: "WeightedCapacity",
    }

@!attribute [rw] instance_type

An EC2 instance type designation.
@return [String]

@!attribute [rw] weighted_capacity

Instance weighting that indicates how much this instance type
contributes to the total capacity of a game server group. Instance
weights are used by GameLift FleetIQ to calculate the instance
type's cost per unit hour and better identify the most
cost-effective options. For detailed information on weighting
instance capacity, see [Instance Weighting][1] in the *Amazon EC2
Auto Scaling User Guide*. Default value is "1".
