    The Internet of Things (IoT) consists in a variety of smart connected objects, among which a category of low-end devices based on micro-controllers. The orchestration of low-end IoT devices is not straightforward because of the lack of generic and holistic solutions articulating cloud-based tools on one hand, and low-end IoT device software on the other hand. In this paper, we describe such a solution, combining a cloud-based IDE, graphical programming, and automatic JavaScript generation. Scripts are pushed over the Internet and over-the-air for the last hop, updating runtime containers hosted on heterogeneous low-end IoT devices running RIOT. We demonstrate a prototype working on common off-the-shelf low-end IoT hardware with as little as 32kB of memory.

    Along with increasing demands for IoT (Internet of Things) solutions for business digitalization, the capability of easy and quick installation of IoT service is highly demanded. To achieve this, we developed a prototype of cloud-IoT orchestration framework providing capabilities of registration of IoT device, business workflow editor and deployment of workflows to IoT device through wireless network. In this paper, we explain the architecture of our framework and demonstrate its capability through a use case scenario of intrusion detection.
