### [Scaling iOS CI with Anka](https://yomu.fyi/post/scaling-ios-ci-with-anka.md)

Shopify needed a unified CI/CD system that could give iOS developers the same reliable, disposable build environments already used for Linux and Android projects. An earlier VMware ESXi setup used a shared storage area network, but its maintenance burden and write throughput limit created stability and scalability problems. The replacement uses Anka, a Docker-like macOS virtualization layer built on Apple’s Hypervisor.framework: one Core i7 Mac Mini runs one VM with local storage, while layered images are pushed to registries and pulled across two MacStadium data centers. Buildkite agents clone temporary snapshots, boot suspended VMs in under a second, run steps, upload artifacts, and delete the VMs afterward. Shopify reports about 350 iOS build jobs per hour for roughly 60 iOS developers, with easier Xcode and macOS upgrades, no shared-storage single point of failure, and horizontal scaling, although capacity remains manually adjusted and spiky demand can increase queue times.
