Defined in:



When passing InstanceDefinition as input to an Aws::Client method, you can use a vanilla Hash:

  instance_type: "c4.large", # required, accepts c4.large, c4.xlarge, c4.2xlarge, c4.4xlarge, c4.8xlarge, c5.large, c5.xlarge, c5.2xlarge, c5.4xlarge, c5.9xlarge, c5.12xlarge, c5.18xlarge, c5.24xlarge, r4.large, r4.xlarge, r4.2xlarge, r4.4xlarge, r4.8xlarge, r4.16xlarge, r5.large, r5.xlarge, r5.2xlarge, r5.4xlarge, r5.8xlarge, r5.12xlarge, r5.16xlarge, r5.24xlarge, m4.large, m4.xlarge, m4.2xlarge, m4.4xlarge, m4.10xlarge, m5.large, m5.xlarge, m5.2xlarge, m5.4xlarge, m5.8xlarge, m5.12xlarge, m5.16xlarge, m5.24xlarge
  weighted_capacity: "WeightedCapacity",

This data type is used with the Amazon 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.

    An EC2 instance type designation.


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 in the Amazon EC2 Auto Scaling User Guide. Default value is \"1\".
