Now when I think about it, is it even possible to run lemmy on a cluster, like a regular web app, or is it a monolith?

There’s a page for info on horizontal scaling Lemmy here: https://join-lemmy.org/docs/administration/horizontal_scaling.html

It does seem to be out of date (for one, it mentions that pict-rs can’t be horizontally scaled due to the sled database, but pict-rs now supports postgres so maybe that has changed.

I know larger instances run a separate federation container and many instances (including mine) run multiple lemmy-ui containers for the front end, but as I understand it the Lemmy backend can only run as a single service.

Is this a real Calvin and Hobbes? AI generated?

It doesn’t look edited but it seems a little too… something.
