Abstract

This systematic review examines the integration of the Internet of Things (IoT) with Cloud Computing (sometimes coined as Cloud of Things), a convergence driving innovation across industries that also presents unique challenges. The study synthesizes research from 2015-2024, focusing on applications, challenges, and opportunities within this rapidly evolving field. A comprehensive search was conducted across IEEE Xplore, ScienceDirect, SpringerLink, Google Scholar, and ACM Digital Library, using relevant keywords and Boolean operators to identify peer-reviewed articles addressing IoT-cloud integration, edge/fog computing, and related architectures. The review adopts a rigorous methodology, including predefined inclusion/exclusion criteria, a multi-stage study selection process, thematic analysis, and SWOT analysis to evaluate recurring themes and assess the strengths, weaknesses, opportunities, and threats of IoT-cloud integration. Critical literature analysis reveals several key themes: architectural innovations in transportation and mobile applications, persistent security and privacy concerns, the rise of edge and fog computing to reduce latency, the need for scalable big data management, and the importance of standardization for interoperability. Research gaps identified include a lack of empirical validation in large-scale deployments, fragmented security frameworks, the absence of unified edge-cloud orchestration, underexplored advanced analytics, and limited open standards. The future research should prioritize real-world testbeds, comprehensive security solutions, integrated edge-cloud ecosystems, intelligent data analytics, open standards, and energy-aware architectures. Addressing these gaps will unlock the full potential of IoT-cloud integration, enabling smarter automation, predictive maintenance, personalized services, and optimized resource utilization across industries. This review offers valuable insights for researchers, practitioners, and policymakers seeking to harness the transformative power of these converging technologies.
