That is a diagram I made when I worked at LiveJournal showing the complexity of the infrastructure. I believe that covered everything, but that was circa 2005. Half a decade later, there have been a lot of changes to how things work.
Dreamwidth is not that complex. It could be, if we were to get as popular as LJ was at the time. We would certainly have to scale things up. Right now we operate a lot of services on one node and we double and triple pack things so that we need fewer servers.
