Serverless computing is one of the hottest trends in software second only to containers. But most serverless function platforms suffer from vendor lock-in and a poor developer experience. Ideally, companies should be able to run their functions on any cloud choosing the one that offers the best value with the knowledge that they could change providers if need be. Developers should be able to build and test on their laptops knowing that the functions platform they’re developing on locally is same platform that’s running in the cloud—not some approximation or emulation. The purpose of the recently announced Fn project is to respond to these needs and to deliver an open source Apache 2.0 licensed functions platform that can run anywhere: laptop, server, cloud. In this session we’ll introduce Fn, its polyglot function support, and its Docker-based architecture that allows it to run on any platform and with any scheduler including Kubernetes, Mesos, and Swarm.
