Feedback Control Loops (FCLs) are the heart of any self-adaptive sys- tem. Existing engineering approaches for building self-adaptive systems mask FCL by providing abstraction layers that hide the application complexity. In this paper, we investigate a model-driven approach for the engineering of FCLs whose archi- tecture is based on the Service Component Architecture (SCA) model. Our proposal consists in exploiting the data streaming model, to specify the characteristics of the control

... , and to generate FCLs of self-adaptive systems deployed in large- scale environment. We argue that the use of a data-oriented model for designing self-adaptive systems significantly increases FCL visibility.
