The management server runs the OnionBalance daemon. OnionBalance combines the routing information (the introduction points) for multiple backend onion services instances and publishes this information in a master descriptor..

The backend application servers run a standard Tor onion service. When a client connects to the public onion service they select one of the introduction points at random. When the introduction circuit completes the user is connected to the corresponding backend instance.
