Use auto-scaling in Amazon GameLift Servers to dynamically scale your fleet capacity in response to game server activity. As players arrive and start game sessions, auto scaling can add more instances; as player demand wanes, auto scaling can terminate unneeded instances. Auto scaling is an effective way to minimize your hosting resources and costs, while still providing a smooth, fast player experience.
To use auto scaling, you create scaling policies that tell Amazon GameLift Servers when to scale up or down. There are two types of scaling policies: target-based and rule-based. The target-based approach—target tracking—is a complete solution. We recommend it as the simplest and most effective option. Rule-based scaling policies require you to define each aspect of the auto scaling decision-making process, which is useful for addressing specific issues. This solution works best as a supplement to target-based auto scaling.
You can manage target-based auto scaling using the Amazon GameLift Servers console, the AWS Command Line Interface (AWS CLI), or an AWS SDK. You can manage rule-based auto scaling using the AWS CLI or an AWS SDK only, although you can view rule-based scaling policies in the console.
