Hi,
More like the bus is only a JMS topic with "distributed" not meaning probably what you hoped for. Since it's based on the ActiveMQ5 it's in HA configuration a single broker with master/slave (which with replicated LevelDB storage would then have ZooKeeper and everything else that's massively complex to manage). So nothing like the networks created by Hazelcast (eg. Vert.x underlying messaging infrastructure) / Storm / Spark / Cassandra / etc.
These restrictions create their own headache when it comes to scaling in Kubernetes for example, but I don't think we need to solve this issue quite yet. Creating components without locking them to a JMS is the key forward however as that would allow changing the implementation if requirements dictate such in the future.

I disagree with the fact where the actual bus-integration component
should reside. The components themselves should have the
capabilities of allowing another component to connect to their
internal "feeds" but the actual component -> bus connector should
be in the Kettle-repository. Why? The bus-connector is highly
dependent on the actual bus implementation. If we would change the
bus in any way in terms of implementation or API, it would require
changes to every Hawkular component (thus, they wouldn't be
decoupled by design) instead of only changing the implementation at
the bus-component.
I haven't worked with the bus yet, but isn't "the bus" just a synonym
for "a distributed JMS topic" ?
