The previous post covered the decision: a live trading node and a backtest worker sharing one broker quota and one set of OAuth tokens, held together with Distributed Erlang instead of a message broker.
This one is the wiring. One OTP application built as two releases, a VPN between two networks, the connector process that gets the worker into the cluster, node naming and cookies, and what a GenServer.call to a process on another machine actually involves.
It's the architecture as originally shipped — including the parts that later turned out to be wrong.
