An IoT electronic device executes services distributed by an IoT service orchestration device. A Lightweight Machine-to-Machine (LwM2M) request message is received. The LwM2M request message contains a LwM2M object identifying hardware resources of the IoT electronic device for which characteristics are requested. A LwM2M command is executed that accesses a LwM2M interface identified based on content of the LwM2M object to determine the characteristics of the hardware resources of the IoT electronic device which are identified by the LwM2M object. A response message contains information identifying the characteristics of the hardware resources of the IoT electronic device. The response message is communicated toward the IoT service orchestrator device. A service image is received for execution which is adapted by the IoT service orchestrator device, responsive to the information in the response message identifying the characteristics of the hardware resources of the IoT electronic device.
