Scaling Amazon GameLift hosting capacity

Hosting capacity, measured in instances, represents the number of game sessions that Amazon GameLift can host concurrently and the number of concurrent players that those game sessions can accommodate. One of the most challenging tasks with game hosting is scaling capacity to meet player demand without wasting money on resources that you don't need. For more information, see Scaling fleet capacity.

Capacity is adjusted at the fleet location level. All fleets have at least one location: the fleet's home Amazon Region. When viewing or scaling capacity, the information is listed by location, including the fleet's home Region and any additional remote locations.

You can manually set the number of instances to maintain, or you can set up auto scaling to dynamically adjust capacity as player demand changes. We recommend that you start by turning on the target-based auto scaling option. The goal of target-based auto scaling is to maintain enough hosting resources to accommodate current players plus a little extra to handle unexpected spikes in player demand. For most games, target-based auto scaling offers a highly effective scaling solution.

The topics in this section provide detailed help with the following tasks:

You can do most fleet scaling activities using the Amazon GameLift console. You can also use an Amazon SDK or the Amazon Command Line Interface (Amazon CLI) with the Amazon GameLift service API.

To manage fleet capacity in the console

  1. Open the Amazon GameLift console.

  2. In the navigation pane, choose Hosting, Fleets.

  3. On the Fleets page, choose the name of an active fleet to open the fleet's detail page.

  4. Choose the Scaling tab. On this tab, you can:

    • View historical scaling metrics for the entire fleet.

    • View and update capacity settings for each fleet location, including scaling limits and current capacity settings.

    • Update target-based auto scaling, view rule-based auto scaling policies applied to the entire fleet, and suspend auto scaling activity for each location.
