1. Intro to Fn in 10 Minutes JeffConf 2/16/18 Chad Arimura VP Serverless, Oracle @chadarimura
2. About Me • Engineer and builder • 3x entrepreneur, most recently founding CEO of Iron.io • Blame us (at least partially) for Jeff
3. What is Serverless?
4. Why Serverless?
5. Introducing the Fn Project • Open-source serverless compute platform created by Iron.io team that built IronFunctions • Can be deployed to any cloud and on-premise • Active w/ 2500+ commits across 60+ contributors • Independently governed with plans for foundation
6. Differentiators • Open source and runs anywhere • Containers as primitives (bring-your-own-dockerfile) • Simple, elegant, and extensible by design • Independent yet vendor backed • Strong enterprise focus (security, scalability, observability, etc.)
7. An Fn Function • Small chunk of code wrapped into a container image • Gets input via STDIN and environment • Produces output to STDOUT • Logs to STDERR The Fn server handles everything else, like the API gateway, piping things around, storing logs, etc.
8. Fn CLI • fn init --runtime go • fn run • fn test • fn deploy --app myapp • fn call myapp myfunc → http://localhost:8080/r/myapp/myfunc
9. Demo #1
10. Fn Flow • Build long-running, reliable, scalable functions with rich sets of language-specific primitives including fork-join, chaining, delays and error handling • Supports complex parallel processes that are readable and testable (including unit tests) with standard programming tools • Java support using CompletableFuture API from Java 8 with JS, Python, Go language support on the way!
