Hi all,

Thinking of some serverless use cases for node-red and am curious if anyone is running it to execute a single flow from content passed in and then exit. Basically a lambda-type use of the product?

The main issue with that model is the startup time of Node-RED is many seconds and that really isn't suitable for a serverless type environment.

@dceejay Welp, i probably should have done that to start with, thanks.

@knolleary Ah, ok. I only have used it in docker and it's hard to see how quickly the startup completes.
