In the case of having our ELB, we could create a topic per a cluster within ELB and then let nodes subscribe to the well known ELB's matching topic. If there's no LB involved, one mgt node can create a topic which corresponds to its domain and then let other nodes subscribe to this Well known topic. > > > Concerns, > > How are we going to incoperate these changes to future releases. > Deployment is part of the carbon kernel.
