13. Serverless Functions, Microservices Build, Deploy & Iterate

15. An Fn Function Code wrapped in a container image
Input from STDIN and environment
Output to STDOUT
Logs to STDERR
The Fn server handles everything else

16. fn init to create a function fn run a function locally
fn CLI
fn init to create a function
fn run a function locally
fn test a function
fn deploy a function or application (a set of functions)
fn call a deployed function

18. Fn Flow
For long-running, reliable, scalable functions with primitives for fork-join, chaining, delays and error handling
Java support using CompletableFuture API from Java 8—Node, Python, Go support on the way!
