Discovering serverless with OpenFaaS
summary
OpenFaaS is a serverless framework that runs on Docker Swarm or Kubernetes and can be installed on-premise quickly (Helm). It provides a gateway that routes and autos-scales functions (demo showed scaling from 1 to 5 replicas), supports any runtime including raw binaries via a lightweight watchdog, exports metrics to Prometheus, and an upcoming watchdog v2 will keep models or DB connections warm (demoed with a Python cat vs. dog classifier preloaded for near-instant responses).
