You don’t need to restart a server periodically.
Server instances of Strix Cloud are designed to allow stable operation even if it is run continuously for long periods of time. You don’t need to restart it periodically. Of course, if you make periodical restarts during the operation, it will run more stably. Strix Cloud, however, has no function to do so, and you need to do it manually.
Please note that restarting a server instance may be required if you change the number of room servers or their configurations. Restarting a server instance may also be required when a server’s load gets too high and the operation becomes unstable. To avoid such cases, you should limit the number of rooms or the number of messages per second appropriately for your game title.
