6 Challenges Wix Faced While Building a Super CI Pipeline

Wix, a web development platform with over 200 million users and 500 backend engineers, has successfully implemented Buildkite to build a scalable, highly concurrent CI solution. This new system significantly reduced the time builds spend in queue from 40-60 minutes to just a few seconds. The main challenge Wix faced was managing different types of builds with varying SLAs and preventing "build storms." By using Buildkite's dynamic pipeline mechanism, resilient notifications, and autoscaling features, Wix was able to meet its requirements for a new build system.
