Web backends. BEAM VM's green threads work excellently for it, you can handle bursty workloads transparently and all you will pay for it is slightly increased latency (and I really mean slightly). I know, many people claim Ruby [on Rails] and Python [Django] do the same but I've seen APM dashboards of such projects and those of Elixir [Phoenix] and Golang [various, most recently GoFiber] apps and the difference is pretty stark. But if you mean the golden path of select/poll then yeah, hard to beat those on their own turf of course.
