AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2026-03-07 · Documentation high

File: AWSCloudFormation/latest/TemplateReference/aws-resource-gamelift-containerfleet.md

Summary

Added PlayerGatewayMode property documentation detailing DDoS protection features, updated location deployment documentation, and clarified scaling policy/tagging descriptions.

Security assessment

The PlayerGatewayMode documentation explicitly describes security features like DDoS protection, traffic validation, and IP hiding. This adds security-related documentation but does not indicate resolution of a specific security flaw.

+A set of locations to deploy container fleet instances to. You can add any AWS Region or Local Zone that's supported by Amazon GameLift Servers. Provide a list of one or more AWS Region codes, such as `us-west-2`, or Local Zone names. Also include the fleet's home Region, which is the AWS Region where the fleet is created. For a list of supported Regions and Local Zones, see [ Amazon GameLift Servers service locations](https://docs.aws.amazon.com/gamelift/latest/developerguide/gamelift-regions.html) for managed hosting.

+Configures player gateway for your fleet. Player gateway provides benefits such as DDoS protection by rate limiting and validating traffic before it reaches game servers, hiding game server IP addresses from players, and providing updated endpoints when relay endpoints become unhealthy.
+
+**How it works:** When enabled, game clients connect to relay endpoints instead of to your game servers. Player gateway validates player gateway tokens and routes traffic to the appropriate game server. Your game backend calls [GetPlayerConnectionDetails](https://docs.aws.amazon.com/gamelift/latest/apireference/API_GetPlayerConnectionDetails.html) to retrieve relay endpoints and player gateway tokens for your game clients. To learn more about this topic, see [DDoS protection with Amazon GameLift Servers player gateway](https://docs.aws.amazon.com/gameliftservers/latest/developerguide/ddos-protection-intro.html).
+
+Possible values include:
+
+  * `DISABLED` (default) -- Game clients connect to the game server endpoint. Use this when you do not intend to integrate your game with player gateway.
+
+  * `ENABLED` \-- Player gateway is available in fleet locations where it is supported. Your game backend can call [GetPlayerConnectionDetails](https://docs.aws.amazon.com/gamelift/latest/apireference/API_GetPlayerConnectionDetails.html) to obtain a player gateway token and endpoints for game clients.
+
+  * `REQUIRED` \-- Player gateway is available in fleet locations where it is supported, and the fleet can only use locations that support this feature. Attempting to add a remote location to your fleet which does not support player gateway will result in an `InvalidRequestException`.
