Prepared containers, startup script,
semi-automated solution.

13. DEMO
 Docker containers run in Bluemix
 Communicate with local machine
 Stops the trains on the Model Railway Track
 Extra: Bluemix integration with DigitalOcean

14. Difficulties
 Bluemix Docker support undocumented
o Base Docker layer is not provided
o Startup script and configuration is hard to come by
o Only 5 ports published (withouta support ticket)
 Bluemix not fully reliable
 Network communication issues
 Monitoring difficulties
