Making a tradeoff between adaptation and integration in adaptive service based systems

Abstract

Adaptation and integration are considered as two complementary aspects service based applications' life cycle. Although these two aspects are complementary, they correlate with each other. The correlation may influence design and runtime decisions and lead us to make a tradeoff between adaptation and integration. In this paper, we propose an approach to find out the correlation between adaptation and integration in an SBA. This approach helps service integrator make decisions consistent with the current system's status. Moreover, over the course of selecting the best adaptation strategy, it takes system constraints into account. To validate the approach, we apply it on an Online bookstore.
