CreateGameServerGroupRequest

Gets and sets the property AutoScalingPolicy.

Configuration settings to define a scaling policy for the Auto Scaling group that is optimized for game hosting. The scaling policy uses the metric "PercentUtilizedGameServers" to maintain a buffer of idle game servers that can immediately accommodate new games and players. After the Auto Scaling group is created, update this value directly in the Auto Scaling group using the Amazon Web Services console or APIs.

Gets and sets the property BalancingStrategy.

Indicates how Amazon GameLift FleetIQ balances the use of Spot Instances and On-Demand Instances in the game server group. Method options include the following:

• SPOT_ONLY - Only Spot Instances are used in the game server group. If Spot Instances are unavailable or not viable for game hosting, the game server group provides no hosting capacity until Spot Instances can again be used. Until then, no new instances are started, and the existing nonviable Spot Instances are terminated (after current gameplay ends) and are not replaced.

• SPOT_PREFERRED - (default value) Spot Instances are used whenever available in the game server group. If Spot Instances are unavailable, the game server group continues to provide hosting capacity by falling back to On-Demand Instances. Existing nonviable Spot Instances are terminated (after current gameplay ends) and are replaced with new On-Demand Instances.

• ON_DEMAND_ONLY - Only On-Demand Instances are used in the game server group. No Spot Instances are used, even when available, while this balancing strategy is in force.

Gets and sets the property GameServerGroupName.

An identifier for the new game server group. This value is used to generate unique ARN identifiers for the Amazon EC2 Auto Scaling group and the Amazon GameLift FleetIQ game server group. The name must be unique per Region per Amazon Web Services account.

Gets and sets the property GameServerProtectionPolicy.

A flag that indicates whether instances in the game server group are protected from early termination. Unprotected instances that have active game servers running might be terminated during a scale-down event, causing players to be dropped from the game. Protected instances cannot be terminated while there are active game servers running except in the event of a forced game server group deletion (see ). An exception to this is with Spot Instances, which can be terminated by Amazon Web Services regardless of protection status. This property is set to NO_PROTECTION by default.

Gets and sets the property InstanceDefinitions.

The Amazon EC2 instance types and sizes to use in the Auto Scaling group. The instance definitions must specify at least two different instance types that are supported by Amazon GameLift FleetIQ. For more information on instance types, see EC2 Instance Types in the Amazon Elastic Compute Cloud User Guide. You can optionally specify capacity weighting for each instance type. If no weight value is specified for an instance type, it is set to the default value "1". For more information about capacity weighting, see Instance Weighting for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.

Gets and sets the property LaunchTemplate.

The Amazon EC2 launch template that contains configuration settings and game server code to be deployed to all instances in the game server group. You can specify the template using either the template name or ID. For help with creating a launch template, see Creating a Launch Template for an Auto Scaling Group in the Amazon Elastic Compute Cloud Auto Scaling User Guide. After the Auto Scaling group is created, update this value directly in the Auto Scaling group using the Amazon Web Services console or APIs.

Gets and sets the property MaxSize.

The maximum number of instances allowed in the Amazon EC2 Auto Scaling group. During automatic scaling events, Amazon GameLift FleetIQ and EC2 do not scale up the group above this maximum. After the Auto Scaling group is created, update this value directly in the Auto Scaling group using the Amazon Web Services console or APIs.

Gets and sets the property MinSize.

The minimum number of instances allowed in the Amazon EC2 Auto Scaling group. During automatic scaling events, Amazon GameLift FleetIQ and Amazon EC2 do not scale down the group below this minimum. In production, this value should be set to at least 1. After the Auto Scaling group is created, update this value directly in the Auto Scaling group using the Amazon Web Services console or APIs.

Gets and sets the property RoleArn.

The Amazon Resource Name (ARN) for an IAM role that allows Amazon GameLift to access your Amazon EC2 Auto Scaling groups.

Gets and sets the property Tags.

A list of labels to assign to the new game server group resource. Tags are developer-defined key-value pairs. Tagging Amazon Web Services resources is useful for resource management, access management, and cost allocation. For more information, see Tagging Amazon Web Services Resources in the Amazon Web Services General Reference.

Gets and sets the property VpcSubnets.

A list of virtual private cloud (VPC) subnets to use with instances in the game server group. By default, all Amazon GameLift FleetIQ-supported Availability Zones are used. You can use this parameter to specify VPCs that you've set up. This property cannot be updated after the game server group is created, and the corresponding Auto Scaling group will always use the property value that is set with this request, even if the Auto Scaling group is updated directly.
