Self-Architecting Software SYstems (SASSY) from QoS-annotated activity models

As the complexity associated with software development has increased, software engineers have sought novel ways to represent, reason about, and compose large-scale software systems. However, the majority of these approaches are geared to technically well versed engineers, making them unwieldy for use in a growing class of real-world pervasive computing systems. In this paper, we propose a new approach intended to address the current shortcomings in service-oriented software systems. Given the functional and QoS requirements specified by a domain expert in an activity oriented modeling language, an architecture satisfying the requirements is generated. We describe our approach in the context of a framework, entitled Self-Architecting Software SYstems (SASSY), which shapes our ongoing research and aims to automate the composition, analysis, adaptation, and evolution of service-oriented software systems.
