Powered-up Continuous Integration via Docker containers

Take a long-established Continuous Integration build chain and keep growing over time in applications complexity and languages/components to be supported. At some point your developers may start complaining about long build times, no easy debugging of failed builds, and only partial isolation during integration/regression tests.
This is a talk about how we learned that, even if applications themselves are not containerized, container technology can be a tool to power-up the build chain and overcome many of the above limitations.
