Democratizing Serverless: The New Open Source Fn Platform

on YouTube ↗39m

" summary

Open source Fn Project runs functions as Docker images, supports Go, Node.js and Java, and uses an FN CLI to build, test (JUnit) and FN run locally before FN deploy pushes images to a Docker registry. Runtime uses STDIN/STDOUT, hot functions keep containers alive (idle default 30s) to avoid Docker startup ~300ms, async calls go to a pluggable queue, servers scale statelessly, routing uses an FN load balancer, metrics to Prometheus and tracing via OpenTracing.
