The focusing concept of Internet of Things (IoT) is quickly changing from inter-connecting uniquely-identifiable embedded devices to 'things as a service'. Thus, diverse IoT services are being incubated by software-driven frameworks and shared/virtual/programmable resources. As a beginning step, in this paper, we discuss how to prepare and inter-connect hyperconverged SmartX Boxes so that it can play the miniaturized playground for IoT-Cloud service realization.
