Availability buffer

An available server buffer, or availability buffer, is a specific number of online and unallocated servers that must exist in a fleet region. You define the target number of available servers with a region’s scaling settings. Depending on the current server density, a region might sometimes exceed its target.

If the number of available servers goes below or above the buffer value, it serves as a signal for the scaling system to increase or decrease the number of available servers. Game Server Hosting calculates the number of available servers by subtracting the number of allocated servers from the total number of servers.

If the number of available servers is below the target number, it adds more servers until the number of available servers matches the target number. Likewise, if the number of available servers is above the target number, it adjusts the number of servers.
