Feature Overview (aka. Goal Summary)  

Customers are looking to take advantage of the price/performance that ARM64 provides for their workloads. For this to be possible, a customer needs to be able to deploy ARM64 HCP worker nodes
 

Goals (aka. expected user outcomes)

I can deploy an ARM64 machinepool type to an existing clusters

Requirements (aka. Acceptance Criteria):

Install option:
Via: CLI, Portal and ARM/API call, I can specify ARM64 instance type(s). If I select those instance types, the resulting worker nodes of the cluster will be ARM64.

Day2:
I can add ARM64 instance types to an existing cluster

Billing:
ARM64 Instance types are billed appropriately and charged the ARO uplift

Documentation Considerations

Provide information that needs to be considered and planned so that documentation will meet customer needs.  Initial completion during Refinement status.

Interoperability Considerations

Which other projects and versions in our portfolio does this feature impact?  What interoperability test scenarios should be factored by the layered products?  Initial completion during Refinement status.
