Game Server Hosting allows you to scale the number of servers in your fleet up and down in response to player demand per region using the scaling system. The scaling system controls when and how regions within a fleet scale up and down. Each region has independent scaling settings that allow you to tailor how they scale.
The region’s scaling settings tell the scaling system the minimum number of servers that should be available within the region and the maximum number of servers that should be available in the region.
- The region’s scaling settings tell the scaling system the minimum number of servers that should be available within the region and the maximum number of servers that should be available in the region.
- The usage settings you define at the build configuration level tell the scaling system how many servers running the connected build can fit on a machine.
- The current number of allocated servers tells the scaling system how many of the servers in a region are in use and not available for an allocation.
The scaling system considers all the build configurations within a fleet and uses the worst-case usage settings to determine how many servers can run per machine. Game Server Hosting uses the worst-case usage settings to prevent the fleet from re-scaling each time you switch build configurations.
It’s essential to understand how the worst-case usage settings impact scaling. For example, if the usage settings allow for three servers to run per machine and the scaling settings require four available machines, the scaling system spins up two machines. The two online machines result in six available servers instead of four due to the usage settings.
Game Server Hosting creates these two additional servers to make the most of the available capacity. By default, these additional servers are in a stopped state and offer a quick way of increasing server availability without needing to start a new machine.
