Abstract

Middleware has emerged as an important architectural component in modern distributed systems. It provides many solutions allowing to hide the management of the distribution of services and computations to the developers. However, its configuration becomes more and more complex, since it must fit application requirements, while adapting to the underlying system capacities. In this paper we propose a customization tool to automate the configuration of the ScalAgent message-oriented middleware. The tool uses the application description (into an Architecture Description Language) to determine and configure the set of middleware modules required to ensure non-functional properties required by the application. It is controlled by an algorithm that tries to minimize some non-functional property management costs. Our performance measurements clearly show the customization advantages.
