Cloud Native, Event Drive, Serverless, Microservices Framework - OpenWhisk
summary
OpenWhisk is an open source, Apache‑2 platform (announced six months earlier) that runs event‑driven code on demand with millisecond latencies using a Kafka queue, Docker invokers and reusable containers. It uses triggers actions and rules to map events (MQTT, Git webhooks, Cloudant change feeds) to functions, supports JavaScript, Java, Python and Swift and is polyglot via Docker runtimes so PHP or Go can be added. Example: a Watson IoT fridge pipeline analyzes sensor readings, writes to Cloudant, fires a change trigger that creates and ships an order if warranty applies.
