Processing IoT Sensor Data with Semi-Stateful Cloud Functions

At Zurich University of Applied Sciences, we are currently building a test track to link applied teaching with research and innovation. Such a facility allows for covering a whole range of topics: programming, autonomous driving, robotics, cloud, serverless, continuums, sensing, open data, data science, and various computing paradigms. We expect a video to be available around November that explains the facility and especially the teaching element. In this research blog post, we already report on interesting observations around the uplink between sensors and FaaS. We expect these insights to bring benefits to companies building IoT-cloud integrations.

Building a Sample MQTT-based Application on OpenWhisk

In two previous blog posts – here and here – we discussed our experience with deploying OpenWhisk on Kubernetes on OpenStack. As applied researchers at the Service Prototyping Lab, we are investigating potential use cases for such setups and for FaaS-based applications in general. In this blog post, we will therefore describe how we built a sample MQTT-based application that shows OpenWhisk in action for sensor data processing for future Internet of Things and smart dust scenarios.

The basic idea of the application is that it consumes data from an MQTT feed, stores it in a database and provides a means to access the database via a web UI. The architecture of the application is shown in the figure below. The application is based on this blog post.
