If its the same architecture then you can copy the tar file to another system and run it. Its the same for Go apps except you get a binary. 
I do not want to recreate all the structure( I basically do web apps). Phoenix provides good defaults. If it was few lines of code then Go is fine, for larger project i prefer Phoenix( prefer might not be the right word since i don&#x27;t have elixir prod apps while i do have Go apps)
