Serverless computing and FaaS (Function as a Service) are the new blacks! They radically change how software is organized, deployed, and charged for. This hands-on session will present Fn project (http://fnproject.io), an open-source project, which features a code-first approach to building polyglot applications on top of a FaaS platform. Together, we will write functions using various languages (ex. Go, Java, Kotlin). We will then discuss the different development phases (bootstrapping, local and remote deployment, testing...) and address aspects such as input & output coercion. We will then discuss an important aspect, i.e. functions orchestration. We will use the Fn Flow API, a distributed Promise based API, to compose multiple functions into meaningful applications. No flow-charts, no exoteric stuff, just plain readable and testable code! And barely any slide, just code, and demos!
