I currently have a Django-based intranet site (Windows Server 2012 w/ MSSQL DB) and will also have a web-app with the same set-up - both will be for company-use only, so at most ~500 users for the intranet and significantly less for the web app.

As a single dev doing smaller scale projects, is there any reason for me to want to move to this sort of setup? I obviously keep my project version controlled on Bitbucket and we run our usual backups on the servers and DBs, but is there something that Docker would bring that I'm just not getting? Or is this better suited for larger scale, super-fast iteration type projects?
