Scaling Faire’s CI horizontally with Buildkite, Kubernetes, and multiple pipelines

The speed and reliability of the CI system significantly affect engineering delivery at Faire. Confronted with scaling hurdles in Jenkins CI, the team pivoted to Buildkite, Kubernetes, and a poly-CI architecture. The once monolithic Jenkins pipeline fragmented into smaller, more efficient pipelines. This migration tackled Kubernetes scaling challenges and GitHub rate limitations. CI failures plummeted, feedback loops accelerated by 50%. Poly-CI vastly enhanced the developer experience, minimizing manual retries. Transitions for frontend and mobile CI are in motion.
