In recent years, it has become easy to construct advanced IoT systems by using a wide variety of cloud services. In this paper, I propose an exercise to build an IoT system by combining multiple cloud services. In this paper, I propose an exercise to build an IoT system by combining multiple cloud services. As an example of the exercise, I construct a system for monitoring elderly people. The students tried the exercise and constructed a system in which the guardian can check the temperature and humidity data of the guardian's house at any time via a storage server. The observed data is converted into a spreadsheet when it is written to the storage. The data is converted into a spreadsheet when it is written to the storage, and a voice interface is available for the guardian to check the status.
