In the simplest sense it's an open source Paas (think Heroku), but with much more flexible technology. It's designed for ops teams who can run a single platform instead of doing custom deployment work for each application and database
Could you also explain to me what running a single platform instead of custom deployment means? A lot of solutions solve that problem. I don't understand how your product does that.
You could think of them as the sysadmins or IT team that powers especially public-facing services and websites. Think Twitter, HN, etc. The people in charge for making sure there are no fail whales are the ops team.
