New – Use Amazon EC2 Mac Instances to Build & Test macOS, iOS, ipadOS, tvOS, and watchOS Apps

Powered by Mac mini hardware and the AWS Nitro System, you can use Amazon EC2 Mac instances to build, test, package, and sign Xcode applications for the Apple platform including macOS, iOS, iPadOS, tvOS, watchOS, and Safari. The instances feature an 8th generation, 6-core Intel Core i7 (Coffee Lake) processor running at 3.2 GHz, with Turbo Boost up to 4.6 GHz. There’s 32 GiB of memory and access to other AWS services including Amazon Elastic Block Store (EBS), Amazon Elastic File System (EFS), Amazon FSx for Windows File Server, Amazon Simple Storage Service (S3), AWS Systems Manager, and so forth.

On the networking side, the instances run in a Virtual Private Cloud (VPC) and include ENA networking with up to 10 Gbps of throughput. With EBS-Optimization, and the ability to deliver up to 55,000 IOPS (16KB block size) and 8 Gbps of throughput for data transfer, EBS volumes attached to the instances can deliver the performance needed to support I/O-intensive build operations.

Mac instances run macOS 10.14 (Mojave) and 10.15 (Catalina) and can be accessed via command line (SSH) or remote desktop (VNC). The AMIs (Amazon Machine Images) for EC2 Mac instances are EC2-optimized and include the AWS goodies that you would find on other AWS AMIs: An ENA driver, the AWS Command Line Interface (CLI), the CloudWatch Agent, CloudFormation Helper Scripts, support for AWS Systems Manager, and the ec2-user account. You can use these AMIs as-is, or you can install your own packages and create custom AMIs (the homebrew-aws repo contains the additional packages and documentation on how to do this).

You can use these instances to create build farms, render farms, and CI/CD farms that target all of the Apple environments that I mentioned earlier. You can provision new instances in minutes, giving you the ability to quickly & cost-effectively build code for multiple targets without having to own & operate your own hardware. You pay only for what you use, and you get to benefit from the elasticity, scalability, security, and reliability provided by EC2.
