Goal: Identify gaps, if any, to support UPI OpenShift deployments on AWS ARM-based infrastructure for both openshift-sdn and ovn-kubernetes.

Problem: Customers have a requirement to run workloads on ARM processor-based infrastructure, but currently there has not been an exploration on OpenShift's ability to support that infrastructure for networking components and features to determine what, if any, gaps exist in our ability to support it.

Use Cases:

• Edge deployments with minimum architecture resources, e.g. IoT, autom
• Mitigating Intel and AMD dependency risks
•  

Open Questions:

• Is this for openshift-sdn, ovn-kubernetes, or both?
• Is there an SR-IOV requirement?
• Does CI exist today for AWS ARM deployments?
• This is AWS-only, with future goals of adding Azure and Bare Metal ARM-based infrastructures

Dependencies (internal and external):

• multi-arch team CI
• OpenShift Container Platform 4.x Tested Integrations (for aarch64, ARM)
