I thought the post might shed more light on their use of Erlang for this service, but it focuses more on high level topology, AWS infrastructure, and load balancing. It's interesting to get a sense of the level of high level deployment tooling they used, because in a way Erlang marketing gives the impression that the language and VM are all you need.

There are some presentations from Wooga about their use of Erlang.

FWIW, here's a earlier post about chat architecture and talks a bit more about how it uses Erlang.
