We’re excited to introduce the [Elastic CI Stack for EC2 Mac](https://github.com/buildkite/elastic-cI-stack-for-ec2-mac), a new way for teams to scale mobile CI/CD pipelines using AWS and Buildkite ⚡️ This new open source stack is created specifically for mobile teams, helping you migrate to AWS-managed servers for increased reliability, security, and speed 📱 Pinterest have been using Buildkite to power their own mobile CI pipelines using a similar architecture to the Elastic CI Stack for EC2 Mac, which you can read all about it in [Oliver Koo’s UnblockConf 21 talk](https://buildkite.com/blog/moving-pinterest-s-ios-builds-to-autoscaled-ec2-mac). Migrating from their self-managed hardware to Buildkite + AWS resulted in an 80% reduction in CI related build failures, and a 43% reduction in upgrade times 📉 This 1.0 release consists of a CloudFormation template that manages the Auto Scaling Group, Launch Template customizations to run the Buildkite Agent, and various supporting pieces required to maintain a pool of EC2 Mac instances running the agent. And coming up we’ll be adding m1 support, new autoscaling options, and more. To get started, see the [Elastic CI Stack for EC2 Mac Documentation](https://buildkite.com/docs/agent/v3/elastic-ci-stack-for-ec2-mac/autoscaling-mac-metal) or check it out [on GitHub](https://github.com/buildkite/elastic-cI-stack-for-ec2-mac) 🚀 If your team manages Linux and Docker based workflows too, check out our existing [Elastic CI Stack for AWS](https://buildkite.com/docs/tutorials/elastic-ci-stack-aws). Or if you'd like to connect with other teams running mobile CI/CD at scale, you can join the [Mobile Native Foundation forums](https://buildkite.com/blog/buildkite-has-joined-the-mobile-native-foundation) and the [Buildkite Community Slack](https://chat.buildkite.community).
