You can read a bit about the Angeldust backend architecture in this comment chain (I have no idea what to call this): https://news.ycombinator.com/item?id=21858618

The Second Life approach sounds like a very good solution if you're having to, and willing to use multiple servers because of performance reasons. I think Angeldust's architecture is a bit cleaner and more straightforward due to different design goals. I specifically wanted to reduce complexity and keep a simple infrastructure so that I could code, debug and manage everything on my own.

I also have the luxury of using a single, big, many-core server if necessary. When Second Life started I don't think 32+-core servers were a thing, so their scaling model was probably also born out of sheer necessity.
