Acceptance-Based Software Architecture Deployment for Improvement of Existing Applications

A lot of approaches are already published to solve software architecture deployment problems. Most of them are intended for academic use and assume that the software components can be deployed freely on the hardware components. But for an improvement of existing applications, non-functional constraints will have a high influence on the acceptance of the automatically generated solutions. In this paper, the organization of the engineers and their tasks as well as the amount of changes regarding to a currently applied system are considered. To gain a smart and reduced interface between hardware components, a method is presented to reduce the communication overhead for an existing architecture. Additionally, the deployment problem is restricted by the amount of changes in comparison to an initial deployment. This approach is tested on a realistic case study to show that it is possible to achieve high improvements with only small changes of the system.
