Cloud-Based Testbed for Large-Scale Data Collection System with Network-Edge.

With the recent development of IoT technology, it is becoming necessary to design systems that utilize not only the cloud but also the edge. We are studying systems that reduce the load on the cloud by performing various processes at the edge. Although experimentation in a large-scale environment is essential for such research, it is impractical to set up such an environment using actual computers. In this study, we attempted to construct a large-scale experimental environment on top of EKS, a container framework on Amazon Web Service and confirmed that it is possible to easily construct a large-scale experimental environment by using containers. Furthermore, we conducted several experiments on the constructed large-scale experimental environment and confirmed the following: 1) The computational load for the MQTT broker is sufficiently small even with high message frequency, 2) With a relay server, we can reduce the broker burden preserving the message delivery latency.
