Greetings Wayfair Engineering Enthusiasts: old, new, and returned. We’re gathered today (virtually) to collect a story from Wayfair’s history. I’m Gary White, volunteering historian, frequent worker. I’m going to share with you all the journey we took as an organization to adopt Continuous Integration. This is part one of two. In part two, I’ll tell you the story of Buildkite at Wayfair. In this part (one), you’ll indulge me in learning about Gitlab CI. Where we started, the good, the bad, the decline, and the eventual decision to scrap our critical build infrastructure to do something new.
