Unlocking AWS Graviton for Java: Continuous Modernization Made Easy

AWS Graviton support for Java exists to help teams modernize their applications efficiently. It automates the discovery of technical debt in your repositories, allowing you to focus on building rather than fixing. By leveraging AWS Transform continuous modernization, you can connect to your source provider, analyze your code, and open pull requests with the necessary changes, all while ensuring compatibility with Arm64 architecture.

The process begins with a readiness assessment that scans your repository for native libraries and architecture-specific code. This assessment identifies any Arm64 compatibility issues, allowing you to address them proactively. The remediation skill then resolves these findings by updating native libraries, upgrading dependencies, and applying necessary JVM flags for Graviton. For instance, you can set your AWS region with export AWS_REGION=us-east-1 and initiate a discovery scan using atx ct discovery scan --source graviton-demo to kick off the process.

In production, you need to be aware that while AWS Transform provisions infrastructure on x86 architecture, it generates Arm64 code changes that you must build and test in your own Arm64 pipeline. This limitation means you can't rely solely on AWS Transform for complete validation before merging your changes. The service has been generally available since October 29, 2026, so ensure your environment is set up with the necessary prerequisites, including AWS credentials and an Arm64 host for remediation.
