Erlang is highly optimized to build reliable network communication systems (application-level routers, message brokers, stream aggregators, perhaps MMO game engines, chat backends, etc.) The secret weapons are actor model and process separation (like microservice architecture, but within a single app), supervision (isolated processes are restarted on failure, there is no difference between known "application" errors and exceptions), and beyond state of the art protocol parsing and construction facilities, for both binary and text protocols. For some tasks (scientific computing, UIs, offline analytics) Erlang might not be the best choice. However, within its domain of applications, it really shines.
