SmartLife applications are emerging as intelligent user-centered systems that will shape future trends in technology and communication. The development of such applications integrates web services, cloud computing, and big data management, among other frameworks and methods. The authors' paper reports on new perspectives of services and cloud computing architectures for the challenging domain of SmartLife applications. In this paper, they explore SmartLife applications in the context of semantic-supported systems architectures and big data in cloud settings. Using a SmartLife application scenario, they investigate graph data management, fast big data, and semantic support through ontological modeling.
