Custom load balancing with open-source shiny-server

If we have a single UNIX server where the application is copied within multiple folders in app directory, can we implement some custom load balancing - for e.g., round-robin, least-connected, etc. approaches?

Default app directory: /srv/shiny-server

|__ /srv/shiny-server
|_______________ /app-copy-1
|_______________ /app-copy-2
|_______________ ...
|_______________ /app-copy-n

NGINX can act as HTTP load balancer - any use of this?

Note: the commercial versions are too costly, hence looking for some way around.
Any thoughts are appreciated. Thanks in advance, fellow developers. :slight_smile:

I think that using shinyproxy or any general purpose container orchestrators like Kubernetes would be a much better solution.
