Cloud Foundry Summit North America 2018

IoT devices are becoming ubiquitous in e.g car-, smarter home, and many other industries. Applications dealing with IoT devices need to react to events and serverless platforms are essentially designed for such workflows. More and more sensors are continuously sensing data, some – often the majority – of this data is more or less neglectable, and some of this data requires attention. The reception of an event on serverless platforms yields the execution of a (set of) function(s). The pricing model is activation based, i.e. the customer is only charged for code really running. As a conclusion, customers are charged for code activations based on irrelevant events.

In this talk, we will show a system build on top of Cloud Foundry, which brings together event management and serverless computing capabilities to do both: Filter (IoT) events and execute actions. The project was generally a PoC, which was implemented as microservice architecture with different technologies (e.g. Golang, Angular JS, NodeJS, Rabbit MQ, etc.). Its aim is to handle events, based on rules set by the user and trigger actions on a serverless platform for handled events only.
We will show our microservice architectural design and talk about problems we faced. Moreover, we will show a demonstration video of an end-to-end scenario using the event handling system.
