Abstract
This paper presents a vision on how to apply the DevOps paradigm in the context of QoS-aware adaptive applications. The goal is to raise awareness on the lack of quantitative approaches that support software designers in understanding the impact of design alternatives at the development and operational stages. To this end, in this paper we: (i) verify the compliance of a design for adaptation approach with the DevOps life-cycle; (ii) perform the runtime monitoring of dynamic IoT systems, through Quality-of-Service (QoS) evaluation of system parameters, to guide a QoS-based adaptation with the goal of fulfilling QoS-based requirements over time.

Note that metrics can be expressed in different units for sensors and actuators of different brands, however such units can be converted to a common reference unit in the DO model, thus to avoid misleading comparison.
