Autonomic Behavior: EDA (event delivery architecture) to be used for event propagation

[fernandohackbart]

The events generated by metric collection, exceptions and external interruptions should be propagated internally using EDA, all the subscriber components will be notified when the event happens in order to trigger actions.

Research hot to implement (or use already implemented) EDA technology

Check also CEP (complex event processing)

In the scope of the Biosphere project, we are researching the Apache Kafka project, it looks to behave exaclty as expected (kind of JMS topic).

Also Akka seems to be another option to event delivery in the tissue.

Akka does not seems to like to be embedded but be the agent, keep checking...

Also for Kafka, if the tissue will manage the cell instances then the stream solution should be controlled by the tissue as well.
