Bitrise has developed a robust CI/CD infrastructure over the past decade to ensure reliability, consistency, and performance for developers. Their infrastructure spans three geographically redundant data centers and employs multiple internet providers to mitigate disruptions. Continuous testing and observability help preemptively identify and address issues, while consistency is prioritized through the use of high-spec Mac Minis with oversized SSDs and custom cooling systems to prevent performance degradation. Bitrise also uses the BitTorrent protocol for efficient image distribution without disrupting ongoing builds, and all machines are equipped with 10 GbE network interfaces to optimize network I/O. Build caching is enhanced by co-locating cache storage on the same high-speed network as build machines, thereby reducing latency and increasing throughput. These infrastructure choices are designed to prevent downtime and ensure fast, reliable builds, ultimately enhancing developer productivity by minimizing the time spent on infrastructure-related issues.
