How Travis CI Uses Heroku to Scale Their Platform

Editor's note: This is a guest post from Mathias Meyer of Travis CI.

Travis CI is a continuous integration and deployment platform. It started out as a project to offer a free platform for the open source community to run their tests and builds on.

Over the past two years, Travis CI has grown, a lot. What started out with a single server running just a few hundred tests a day turned into a platform used by thousands of open source projects and hundreds of companies for their public and private projects. Travis CI is currently serving more than 62,000 active open source projects, with 32,000 daily builds, and 3,000 private projects with 11,000 daily builds.

Heroku is an important part of how we’ve scaled our platform, and this is the story of how we did it.
