CAFISE: An Approach to Enabling Adaptive Configuration of Service Grid Applications

Aiming at building up more powerful, open-standard-based and genericinfrastructures for application integration, service grids address thechallenges in large-scale coordinated sharing and on-demand compositionof network-based application services. The related endeavors have opened upnew ways of application development, deployment and integration. Inconnection with the new level of scale, openness and dynamism broughtforward by service grids, adaptive service configuration is ofessential importance to applications. This paper proposes an approachcalled CAFISE, which tries to better facilitate on-demand configurationand dynamic reconfiguration of service grid applications. In CAFISE, abusiness design and its supporting software system are considered in acoherent way, and a convergent relation, which helps to mapbusiness-level configurations to software-level configurations, ishighlighted. The paper is particularly devoted to presenting anddiscussing the principles, reference model, modeling language andsupporting application framework of CAFISE. Since practical usefulnessis highly valued in the development of CAFISE, the application of theapproach to a real-world scenario is also presented in the paper.
