From the Developer Portal, you can configure how Rooms are created through the SDK in the coherence cloud.
From the left sidebar, select Rooms. On this page you can:
choose the regions you want to allow your rooms to be created in
enable Simulators for your Rooms
view a list of recently created Rooms
From the Developer Portal, you can configure what size you want your Simulator instances to be. To attach a Simulator to a Room, send the "Simulator slug" uploaded through the SDK with the Rooms creation request. When using the PlayResolver to create Rooms, the Simulator uploaded through the SDK is automatically assigned in the creation request.
