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.

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!
