    Industry 4.0 aims at evolving the current industrial processes towards directly connecting shopfloor machines to systems from different layers of the automation pyramid, such as Enterprise Resource Planning (ERP) or Manufacturing Execution Systems (MES). There are key functional and quality requirements that apply to most Industry 4.0 systems independent of the application domain, e.g., requirements related to interoperability, recoverability, security, and modifiability. Despite their importance, there is still a lack of understanding of (i) architecture drivers that focus on these quality aspects and (ii) architecture solutions for these architecture drivers that are adequate for a wide range of Industry 4.0 contexts. To contribute to filling this gap, we present in this paper (i) quality-centered architecture drivers derived from industrial cases, and (ii) architecture solutions based on the concepts of Digital Twins, Service-Oriented Architecture, and Virtual Automation Bus for four recurrent production plant scenarios. The architecture drivers and solutions presented in this paper were instantiated in different Industry 4.0 contexts, such as BaSys 4.0 (the German national reference project for Industry 4.0), and by the BaSys industry project partners.

    Continuous software engineering aims at orchestrating engineering knowledge from various disciplines in order to deal with the rapid changes within the ecosystems of which software-based systems are part of. The literature claims that one means to ensure these prompt responses is to incorporate virtual prototypes of the system as early as possible in the development process, such that requirements and architecture decisions are verified early and continuously by means of simulations. Despite the maturity of practices for designing and assessing architectures, as well as for virtual prototyping, it is still not clear how to jointly consider the practices from these disciplines within development processes, in order to address the dynamics imposed by continuous software engineering. In this regard, we discuss in this paper how to orchestrate architecture drivers and design specification techniques with virtual prototypes, to address the demands of continuous software engineering in development processes. Our proposals are based on experiences from research and industry projects in various domains such as automotive, agriculture, construction, and medical devices.
