Serverless IoT Framework

This paper presents the Serverless IoT Framework (SIF), a unified programming framework for IoT applications in the Edge Cloud Continuum based on Serverless Computing. It enables to bundle applications for the cloud, edge, and IoT devices, all written in a FaaS style where state-less functions subscribe to events that are created by various kinds of triggers. The execution of invocation can be optimized in space and time across federated FaaS platform and local execution resources of devices. Functions specify required resources, such as special sensors on device-level, as well as required data and the required response time. The execution of invocations is then optimized based on the given information. This paper introduces the SIF concepts and the implementation platforms on device and edge/cloud levels. We demonstrate the usage and available optimization within an example.
