Things to Keep in Mind When Working with Vercel

The article is very short and only covers the bare bone basics.
I personally use Vercel for my SvelteKit and React apps, but I don’t think I’d use it for the backend, for all the limitations the article is exposing (the server is not always on, websockets problems and the way you have to handle your DB).
I will stick with my current configuration for backend.

Anyone deploying backend on vercel should be careful and understand vercel pricing on “Function Invocations” and “Function Duration” very well.
TLDR , you will run out of free quota very fast.
