Starting today, you can launch builds on three new compute types, ARM, GPU and X-Large, when using AWS CodeBuild.
AWS CodeBuild’s support for ARM-based workload allows you to build and test your software updates natively, without needing to emulate or cross-compile. You can get started by creating or updating a CodeBuild Project, and selecting "ARM_CONTAINER" as the environment type and "BUILD_GENERAL1_LARGE" as the compute type. A new managed image, "aws/codebuild/amazonlinux2-aarch64-standard", based on Amazon Linux is now available for you to use as the build environment for these builds.
