Building a Dynamic Mobile CI System - Shopify

This post details the revamp of Shopify's mobile CI system, moving from static configurations to a dynamic, virtualized infrastructure using Buildkite, VMware, and MacStadium's Private Cloud. Key improvements include faster build times (under 10 minutes), enhanced scalability through linked clones and a scheduler/worker VM architecture, and greater flexibility in managing OS and toolchain versions. The system addresses the specific challenges of iOS and Android builds, including code signing and emulator acceleration, and emphasizes the importance of investing in appropriate hardware for efficient CI operations.
