A Catalogue of Architectural Decisions for Designing IIoT Systems.

Designing Industrial IoT (IIoT) systems enforces new sets of architectural decisions on software/system architects. Although a rich set of materials for architecting enterprise software systems exist, there is a lack of reference documents on architectural decisions and alternatives that architects face to design IIoT systems. Based on our experience in designing IIoT systems in various domains such as process automation, discrete manufacturing and building automation, we provide a catalogue of architectural decisions, their impacts on the quality attributes of systems, and technology options to realize each design alternative.
