Hi, the foreman gem isn’t specific to the Ruby Language because it can be used with many different languages and frameworks.
Next, if these processes are Erlang processes, then one can use supervisors to startup dependent processes depending on your overall process architecture.
At this time, I prefer working with Docker and Kubernetes because I can easily setup and execute the same environment locally that will eventually run in staging and production.
In short, the tools that you have learned in the past may be still relevant in the now. Also, look at leveraging general purpose tools that can used across languages and frameworks.
