Here is how I'm using it personally: I have a handful of VPS's. Every once in a while I find a fantastic deal on one and add it to my "collection." Instead of trying to manage which VPS has what running on it - I use docker. Or rather I am migrating to it, still not 100% complete. It is quite powerful in this regard, allowing me to write small separate applications that run completely agnostic from their underlying hardware/virtualization. If I cancel a VPS, I just move the container over with a couple simple commands. So how is this useful? This morning I decided I wanted to have access to a HTTP-DNS tunnel. I launched iodine in a docker container and pushed it to one of my servers - if I need to move it to a different one, it's just a couple commands away from happening without having to reset or rebuild anything. I have a handful of web scrapers, RSS monitors, an IRC bouncer, etc running in docker containers that make management much easier than my previous solutions. Now as for a more "professional" use? I'm not as sold on it. If your server has room for multiple "things" running on it - you a.) need multiple smaller servers or b.) your application isn't large enough to even need docker to begin with. But of course this isn't applicable to everything and docker definitely has other benefits that depending on your software may or may not be useful.
