Abstract: The rapid expansion of the Internet of Things (IoT) and the increasing reliance on wireless connectivity have driven the integration of cloud computing into large-scale IoT ecosystems. While cloud-based solutions offer elastic resources and centralized management, the growing number of connected devices, heterogeneous workloads, and dynamic wireless conditions pose significant challenges in terms of scalability and adaptability. Traditional Cloud–IoT architectures often struggle to efficiently accommodate massive device connectivity, fluctuating data rates, and varying quality-of-service requirements. Consequently, there is a growing need for architectural designs that can dynamically scale resources and adapt system behavior in response to changing network and application conditions. This review paper provides a comprehensive analysis of scalable and adaptive Cloud–IoT ecosystem design for wireless networks. It examines foundational architectural models, wireless communication technologies, and cloud computing paradigms that support IoT deployments. The paper further investigates scalability challenges related to device density, data volume, network capacity, and resource provisioning, as well as adaptability mechanisms that enable context-aware, autonomous, and mobility-aware system operation. Key architectural approaches, including edge and fog computing, microservices, containerization, and serverless computing, are reviewed and compared. In addition, the paper discusses resource management, orchestration strategies, and critical considerations related to security, privacy, and reliability. Through a comparative analysis of existing solutions and an exploration of application domains, the review identifies current limitations, trade-offs, and open research challenges. The paper aims to guide researchers and practitioners in designing resilient, efficient, and future-ready Cloud–IoT ecosystems for dynamic wireless environments.
