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.
