One of the areas where AWS IoT Core lacks is in terms of the fact that it does not serve as a good visualization tool like Grafana or Kibana, making it an area where improvements are required. It is quite ugly to see the visualization part offered by AWS IoT Core, so the data pipeline did upset some of the clients who used it. Visualization is a very important key feature, in my opinion, because most people would like to see results from graphs, etc., for which visualization, in my opinion, is a key feature. The tool wasn't very easy to configure.
