I was thinking about this in regards to all the “defederation” posts.

Let’s say you spin up a server and over night it gets super popular and grows enormous. Now your yearly expenses shoot up and you’re forced to either look for a new host or shut down.

Now what if instead, you could get a few other people to spin up more small instances and distribute parts of your biggest communities to them, however the users don’t notice because The communities are looking across instances instead of within their home instance?

That’s the idea at least. This would allow for many things but most importantly, it would make things a bit more manageable. Thoughts?

Would it be possible to have the dns of the instance technically be a load balancer and just point to different instances of the same docker container, but keep the database as a single shared entity?

Edit: oh OP is talking about doing this on a sublemmy level instead of a site wide level. Would my idea work for the entire instance?

dns of the instance technically be a load balancer and just point to different instances of the same docker container What you actually mean is the lemmy docker be loadbalanced. The DNS will only point to the loadbalancer.

This is still somewhat doable and easier than what OP is asking for but I'm unsure whether lemmy can handle the synchronization issues. My instance manager (lemm.ee) has kind of distributed his architecture by decoupling core components of lemmy. Example

DB on one server
Loadbalancer on another server
Main lemmy instance on one server
