Build Infrastructure Engineering for Open Source at Travis CI

Travis CI has hosted open source since 2011, running almost a million Open Source builds per week, including many Open-Infrastructure projects.  This full-length talk will have three parts:

1) High-level detail of Travis' own build infrastructure
2) Technical and process challenges involved in running and maintaining build environments for a variety of operating systems, languages, and features for Open Source communities
3) Lessons learned and path forward.
Goal of talk:  give audience information to better understand potential trade-offs in making technical and process decisions in their own projects.
