Future computing (FC) is a technology of real-world Internet of things on cloud computing with respect to IT convergence that has emerged rapidly as an exciting new industry and life paradigm. Future computing is being used to encompass the cloud, big data, and cloud data centers that are the megatrends of the computing industry. This technology is making a new future market that is different from the past and is evolving toward gradually eroding the existing market. Internet of things is a vast and dynamic territory and is evolving at a rapid pace. The realization of the Internet of things vision brings ICT technologies closer to many aspects of real-world facing serious issues such as global warming, environment protection, and energy saving on cloud computing. Advanced technologies in sensing, processing, communication, and services are leading to IoT service in our life such as industry, army, and life paradigms on cloud computing environment. There might be many issues to realize and provide smart services, and much effort and enormous attention have been focused on Internet of things on cloud computing technologies. Theoretical research contributions presenting advanced technologies, concepts, or analyses, reports on experiences and experiments of implementation and application of theories, and tutorials on new trends should be needed on this research fields. For the aforementioned reasons, the special issue intends to give an overview of the state of the art of issues and solution guidelines for the FC services with IT convergence. 2 Related works Meng et al.
