Automated publish-subscribe middleware configuration with M2etis

We present Massive Multiuser Event Infrastructure (M²etis), a configurable publish-subscribe middleware. M²etis uses discrete-event simulations and regression methods to translate declarative descriptions of event types in terms of the application domain to an optimal configuration. Configuration decisions are based on the Quality-of-Service (QoS) requirements of the application and are conducted by a configuration component at design-time to minimize performance impacts at run-time. The demonstration shows how the M²etis configuration workflow can be applied to the application domain of Massively Multiplayer Online Games (MMOGs). We explain the configuration workflow as conducted by the M²etis configuration component and illustrate how it can be integrated into the development lifecycle of distributed applications.
