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.
The ops team at a company is the group responsible for running and scaling the apps after they've been written. The role varies from company to company, but in general they manage databases, underlying infrastructure, and other technology that power apps.
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.
This is a nitpick, but it really turns me off from coming back to applications, and I'd want to know about it if I were you: after I registered on dashboard.flynn.io, neither the password remembering functionality built into chrome nor my password manager (LastPass) seems to know how to autofill your login form. I haven't looked into why that would be at all, but it's a real nuisance!
"Non-cooperating services often use service discovery information in configuration, such as the backends for a load balancer defined in an HAproxy configuration. A generalized configuration rendering system is used to tie service discovery into most non-cooperating services."
The problem is to generate the config file, which etcd doesn't help.
One thing that I really like with other PasS companies is that they package that content up -- setup, architecture, documentation of a n-tier application (I am assuming you already built something like that for contracting work). How would I create a website with database and caching ect... using your services.
