I hope that the "why" is that it's much simpler to use on a small scale. What I'd really like is a standardized engine to deploy apps of many flavors on rather than having to create new chef scripts to deploy everything I write.
I essentially want something that works like heroku as far as ease of use for deployment/scaling, accommodates many different application types, and is easy for me to spin up in a 2-4 node cluster on my own VPSes. Every time I have a new app to deploy I just push it to the cluster and I'm done, adding additional VPSes as it starts to get full. I'm hoping this is such a thing, but I haven't tried it just yet, so I can't say for sure.
CloudFoundry, OpenShift, etc. seem pretty heavyweight and more meant for service providers or large corporate private clouds. If they can be used like I describe too could anyone provide some links to docs/blogs about it? I haven't found it so far.
The original motivation wasn't exactly that, but we changed it. At the first moment, we started an open source platform as a service based on Globo.com needs. That's why tsuru first supported EC2 instances. But that's pretty expensive: having 10 virtual machines for an app is not cheap, and does not fit in most company's budgets.
That's why we started implementing support for application containers, and we need to work on documentation and facilitate the life of people willing to deploy tsuru.
