Cloud computing exploits the software as a service model with distributed and interoperable services for the composition of software systems. Cloud-enabled systems that demand elasticity, scalability, and composition of services, etc., there is a need to capitalize on reusable solutions exploiting patterns and styles to architect cloud-based software. The objective of this research is to build and exploit a catalog of patterns that support reusable design knowledge to develop cloud-based architectures. We propose a three-step process with (i) pattern discovery, (ii) pattern documentation (building the catalog), and finally, (iii) pattern application (exploiting the catalog) to enable pattern-based architecting of cloud systems. We discovered seven patterns as generic and reusable solutions and demonstrate the pattern-driven architecture of the ECMC case study. Results suggest that pattern-based architecting enables the reuse of generic design decisions but lacks fine-grained architectural design. The solution is the first attempt towards establishing the catalog as a repository of patterns for architecture-based development of cloud systems.

In this article, we introduce a framework that can be used by organizations as a positioning instrument to think of business-ICT alignment decisions in light of the strategic importance of ICT (Information and Communication Technology) in their organization. We make a distinction between organizations where ICT is of high strategic importance and those where ICT is of low strategic importance. Based on this difference we argue that heavily investing in business-ICT alignment processes, structures and roles (PSRs) will not necessarily always be beneficial when ICT is of low strategic importance to the business. Furthermore, organizations that have a minimalist approach to the use of ICT do not necessarily need to invest in business-ICT alignment PSRs. We explain the dynamics and possible migration scenarios of our proposed framework after testing the statistical significance of the relationship between the strategic importance of ICT and the investment in business-ICT alignment. We end this article with a short empirical study which combines survey and case study results. Both the framework and framework dynamics still need further empirical validation, preferably with longitudinal data. Therefore, we stress and acknowledge that many of the discussions in this article are still explorative in nature. However, this article illustrates the possibilities and the need for a more fine-grained approach to business-ICT alignment.

This paper aims at discussing the potentials of bottom-up design practices in relation to the latest developments in Information and Communication Technologies (ICT) by making an in-depth review of inaugural cases. The first part of the study involves a literature study and the elaboration of basic strategies from the case study. The second part reframes the existing ICT tools and strategies and elaborates on their potentials to support the modes of participation performed in these cases. As a result, by distilling the created knowledge, the study reveals the potentials of novel modes of ICT-enabled design participation which exploit a set of collective action tools to support sustainable ways of self-organization and bottom-up design. The final part explains the relevance of these with solid examples and presents a hypothetical case for future implementation. The paper concludes with a brief reflection on the implications of the findings for the future of architectural design education.

The case study presented in this chapter discusses the design and implementation of an online platform, “come_NET,” in the context of intercultural computer clubs in Germany. This tool was built in close cooperation with the children and adult computer club participants. It was designed to foster the sharing of ideas and experiences across distances, support collaboration, and make skills and expertise accessible to others in the local neighborhood contexts. In particular, the participatory-design process involving the children in the computer clubs fostered a profound understanding of the platform structure and functionalities. The study results show how younger children in particular were able to benefit, as the closed nature of the platform enabled them to gather experience as users of social media, but in a safe and controlled environment.

Remote communities such as rural villages, post-disaster housing camps, and military forward operating bases are often located in remote and hostile areas with limited or no access to established infrastructure grids. Operating these communities with conventional assets requires constant resupply, which yields a significant logistical burden, creates negative environmental impacts, and increases costs. For example, a 2000-member isolated village in northern Canada relying on diesel generators required 8.6 million USD of fuel per year and emitted 8500 tons of carbon dioxide. Remote community planners can mitigate these negative impacts by selecting sustainable technologies that minimize resource consumption and emissions. However, the alternatives often come at a higher procurement cost and mobilization requirement. To assist planners with this challenging task, this paper presents the development of a novel infrastructure sustainability assessment model capable of generating optimal tradeoffs between minimizing environmental impacts and minimizing life-cycle costs over the community’s anticipated lifespan. Model performance was evaluated using a case study of a hypothetical 500-person remote military base with 864 feasible infrastructure portfolios and 48 procedural portfolios. The case study results demonstrated the model’s novel capability to assist planners in identifying optimal combinations of infrastructure alternatives that minimize negative sustainability impacts, leading to remote communities that are more self-sufficient with reduced emissions and costs.

The world-wide crisis caused by the Coronavirus disease 2019 (COVID-19) pandemic had a significant impact on the global economy functioning and the sustainable development of supply chains. The changes also affected seaports being the key links of maritime supply chains. The purpose of the research study described in this article was to identify the sources and kinds of disruptions observed in various maritime supply chains as a result of the COVID-19 pandemic and their impact on the operations of various types of seaport terminals, namely those serving bulk (universal, specialised) and general cargoes (universal, specialised). An additional purpose was to identify the dependencies between the type of terminal and its main function, and the tactical decisions adopted by the particular terminals. The research was carried out using the multiple-case study method. The study covered some selected port terminals functioning in Polish seaports (Gdańsk, Szczecin, Świnoujście), applying direct, semi-structured in-depth interviews. The analysis of the results was carried out using the inductive reasoning method. The research study has shown that as a result of the COVID-19 pandemic some maritime supply chains ceased to exist, some of them were operating with decreased cargo volumes, while in other cases the transshipment volumes actually rose during the pandemic. Among terminal operators’ tactical responses to disruptions in maritime supply chains, there were pro-active and adaptive measures. Pro-active (offensive) measures included actions taken by an enterprise in order to engage in new maritime supply chains, and even participating in establishing new maritime chains in response to limitations caused by the pandemic. Adaptive (defensive) measures covered actions taken by the port terminals as a consequence of changes in the existing maritime supply chains, caused by the pandemic in the port’s foreland or hinterland. The research study results revealed that the terminals extent of engagement and tactical decisions related to the pandemic were depended on the type of terminal (universal or specialised) and its main function played within a supply chain.
