You don’t need complex microservices do get some benefits from reproducible production environments. If you have multiple machines and need all of them to have an identical environment, there is no better way. Everything else is ridiculously error prone and complicated. Ever tried to debug why two Java installations have different classpaths? Good luck. Need to upgrade different system level dependencies but your applications needs a specified version? How will you do that? Docker is like the static typing of deployments. It may seem a bit over the top at first, but it will really make your life easier.
