Tell us about your request Add support for ARM64 architecture when running Batch jobs on AWS Fargate.

Which service(s) is this request for? Batch, Fargate, ECS.

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard? There is already ARM64 support for ECS tasks running on AWS Fargate that we use extensively. The runtime platform can be specified in the task definition parameters. However, there is currently no option for specifying the runtime platform for Batch jobs running on AWS Fargate in the job definition parameters.

We use Batch jobs for a substantial portion of our workload and being able to use ARM64 architecture would lower the costs significantly.

Are you currently working around this issue? No, we use x86-64 architecture for the workload.
