I covered a bit more of why in the first article here: https://www.conetix.com.au/blog/what-is-docker

Do you deploy individual services to isolated AWS instances or are they on the one instance? Do you ever hit dependency issues upgrading some of the services? Do you ever hit the "worked in development" type production pushes? If so, Docker may be of interest to you.

Of course, if it's not broken then you don't need to fix it. Docker can't solve issues if they don't exist in your environment and it's not a 100% fit for every scenario. It's still worth having a play so that you know how it all works, once you start using it it'll make a bit more sense.
