How to Build a Distributed Serverless Polyglot Micro Services IoT Platform
summary
A runnable, open source event-driven platform is described that ties OpenWhisk actions to triggers via a Kafka message bus, stores code in CouchDB and executes functions in ephemeral Docker containers on invoker nodes. Deployments run locally (Vagrant/docker) or on Bluemix; actions support many languages or a custom Docker image. Triggers include HTTP, MQTT/RabbitMQ feeds and scheduled jobs; billing is per-millisecond and activation latency is optimized. The architecture is a working prototype and is deployed both locally and as a hosted service.
