The document discusses OpenFaaS, a serverless functions framework. It covers installing OpenFaaS, creating functions, autoscaling, and deploying functions on Kubernetes. It also summarizes why OpenFaaS was chosen over other serverless options and how to get involved in the community. The presentation includes a live demo of installing OpenFaaS and invoking functions.

23. Write a function
// Handle a serverless request
func Handle(req []byte) string {
return fmt.Sprintf("Hello, Go. You
said: %s", string(req))
}
handler.go
Use tools like dep for vendoring
faas new hello-nl --lang go -p ewilde
