Dan recently built an internal Heroku from the ground up, using various open source components and bolting them together with Python. He will give an experience report of how he built it and what he learned. (In particular what he'd do differently if he did it again!)
The stack looks something like:
- hand-rolled web-based DNS editor
It has enabled lots of non-programmer techies (network, data center, infrastructure, telecoms, etc.) to roll their own mini apps and deploy them with zero effort.
