Answer 1

You need to use message broker like ActiveMQ / RabbitMQ etc. Either you can set a seperate node for message broker or you can also set it on any node in your 2 cluster node.

Next thing you need to configure enableStompBrokerRelay in your WebSocketConfig on both nodes.

  @Override
  public void configureMessageBroker(MessageBrokerRegistry config) {
    config.setApplicationDestinationPrefixes("/app");
    config.enableStompBrokerRelay("/topic","/queue").setRelayHost("MQHOSTNAME").setRelayPort(MQPORT);
  }
