Scope and architecture

ROSA is a managed OpenShift platform on AWS; EKS is a managed Kubernetes service. Choose based on whether the team needs OpenShift's platform and operating model, rather than treating both names as identical Kubernetes hosting packages.

A common Kubernetes API does not make cloud storage, ingress, workload identity and network policy configuration automatically portable. OpenShift also adds its own platform conventions and administration model.
