To be fair you wouldn't just expose your server directly nowadays, you'd have them in a container orchestrator like k8s that would have a liveness probe (and container usage tracking) that would appropriately scale/restart pods as to not have the system going down, together with load balancers and DDoS protection systems like AWS Shield to detect such attempts. 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).
