[curiously]

well not exactly a business case but it's obviously a win for developers.

I shed a single tear when I realized I could just fire up flask + nginx + uwsgi within seconds after installing docker.

For a business perspective, it's a little tricky. I guess it can help if you need to offer an onsite version of your SaaS app and the enterprise client had strict rules about being on site.

What would really make docker kickass is if they had a way to encrypt all the source code somehow and protect it.
