my employer uses erlang because it's a huge leap forward operationally over ruby/python/go/java. the erlang/otp concept of a release is extremely straightforward and reliable and the beam (erlang/elixir vm) run time introspection and debugging tools are second to none. it's trivial to attach to any running application and get a REPL with full access to the environment. you can even update running code in place
how do people typically put security (authentication and authorization) around this? You wouldn't want just anyone to be able to connect to your running apps, of course. From what I saw in Elixir, there's some kind of cookie/session key that you can specify, but is that it or is there more?
