Recent research in cloud computing infrastructure for IoT data processing focuses on designing scalable, efficient, and intelligent architectures to handle the massive volume, velocity, and variety of data generated by IoT devices. Studies emphasize integrating cloud platforms with edge and fog computing to minimize latency, improve real-time analytics, and ensure seamless data flow between devices and cloud servers. Advanced frameworks leverage containerization, serverless computing, and AI-driven orchestration to enhance resource utilization and processing efficiency. By enabling elastic scalability, interoperability, and high-performance data management, cloud computing infrastructures play a crucial role in supporting IoT-based applications across domains such as smart cities, healthcare, and industrial automation.
