Today?s entreprise-level applications are often built as an assembly of distributed components that provide the basic services required by the application logic. As the scale of these applications increases, coarse-grained components will need be decoupled and will use message-based communication, often helped by Message-Oriented Middleware or MOMs.
In the Java world, a standardized interface exists for MOMs: Java Messaging Service or JMS. And like other middleware, some JMS implementations use clustering techniques to provide some level of performance and fault-tolerance. One such implementation is JORAM, which is open-source and hosted by the ObjectWeb consortium.
The full version of this paper intends to describe performance modeling of various clustering configurations and validate our model with performance evaluation in a reallife cluster. In doing that, we observed that the resource-efficiency of the clustering methods can be very poor due to local instabilities and/or global load variations.
