I use Graviton instances in my Blueprint cluster by using Karpenter. I specified

{
    'key': 'kubernetes.io/arch',
    'operator': 'In',
    'values': ['amd64', 'arm64']
}

in my default provisioner's requirements, and Graviton. You can then put nodeSelector and nodeAffinity on pods, to decide on which arch to schedule them. If your containers use multi-arch images, you can let it do its thing and automatically pull the right image for the selected node's arch. If you don't specify the nodeSelector/affinity on arch, you risk running into CrashLoopBackOff issues, because images are pulled for the wrong arch, and you get executable format errors.

@Feder1co5oave Appreciate you spending time to give us some thoughts around a Graviton Pattern. We would highly encourage you to submit a PR for a new Graviton pattern to our https://github.com/aws-samples/cdk-eks-blueprints-patterns repo if you are interested. This will be a good contribution to the community based on all your work on this. Following is what we need.

1. A complete Pattern for Graviton nodes from EKS with all supported addons along with a workload. Check this for Sample Pattern - https://github.com/aws-samples/cdk-eks-blueprints-patterns/tree/main/lib/secure-ingress-auth-cognito
2. A Complete Readme file which has complete instructions to run the Graviton pattern. Check this for sample readme for a pattern - https://github.com/aws-samples/cdk-eks-blueprints-patterns/blob/main/docs/patterns/secureingresscognito.md

I will be more than happy to work and guide you if you are willing to submit a pattern as a contribution to community.
