Multiple application server cluster with single messaging engine bus

This configuration features multiple application server clusters with only a single messaging engine bus member. This allows further scaling of applications where necessary, but keeps a simple messaging configuration.

A single messaging engine is much easier to manage than a more complex configuration however, if messaging traffic becomes too high, the single messaging engine will become a bottle neck and limit scalability.

Figure 1. Multiple application server cluster with single messaging engine bus configurationIn this figure, external bus members connect to the messaging engine of a bus member that is inside a bus.

If messaging traffic is expected to be too great for a single messaging engine, multiple bus members should be considered.
