So they're serverless. Except the server you're running it on. And the lamba/style code they wrote and uploaded to it.
But serverless, because no ops staff required. Except the ones who installed and maintain this.
This is like a snake eating its own tail and wondering what hurts.
Edit: despite my sarcasm, it's always good to see open-source solutions to reduce reliance (or risk of reliance) on closed vendor solutions. Just stop calling it serverless, and I'll stop telling you how fucking ridiculous that name is.
