> And of course, you can also use a more low latency high availability oriented language handling the frontend (like Elixir, which will have trouble doing the heavy data oriented stuff Julia can), with Julia as a microservice to handle the actual backend logic and analytics, which is probably the setup I'd go for (using 2 high level lispy-languages with very different qualities, each doing what it does best).

I would do this exactly too, if I had to do number crunching.
