Move functions to Arm64 about aws-serverless-ecommerce-platform

[nilskelleter]

Hi Nicolas,

maybe I can support with this task.

Do you already know that it is "only" necessary to add the architectures parameter to the SAM templates or do you expect any issues with some dependencies which have no ARM64 support?

Regards

Nils

Hey @nilskelleter !

Thanks a lot for the help here! In theory, it should work. I've been building and deploy this project from both Linux and MacOS without issue, so I'm assuming there are no compilation is needed. That said, some libraries might package their own binaries which might not have Arm64 support.

In my PR only the services delivery, delivery-pricing, orders, payment, platform, products, users sand warehouse service are covered at the moment.

The payment-3p is not covered because I shortly checked the @aws-cdk/aws-sam documentation (https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-sam.CfnFunction.html) and it looks like that the CfnFunction class currently does not support Arm64. But I have no experience with CDK yet, so maybe there is another solution.

Also the CI/CD pipeline is not changed. Maybe the image of the BuildProject should be changed from aws/codebuild/standard:3.0 to aws/codebuild/amazonlinux2-aarch64-standard:2.0. But I don't oversee the consequence of this change at the moment for the complete pipeline.
