We are doing POC where, we have existing DEV and PROD ready AWS EKS cluster 1.19, especially running using AWS CNI plugin v1.7 and on linux platform. Question - before we spend time and researching, possible to add EKS Worker nodes (windows platform) to existing AWS EKS cluster or should we have seperate EKS Cluster for Windows only nodes ?

I think the documentation on this is pretty clear. For example here: https://docs.aws.amazon.com/eks/latest/userguide/windows-support.html

So it seems that:

  • You indeed can add windows nodes to an EKS cluster. They will be configurated in a separate nodegroup inside your EKS cluster.
  • You should always have at least one Linux node in your EKS cluster (so that would be in a separate node group) to run core EKS services.

    Amazon EKS clusters must contain one or more Linux nodes to run core system pods that only run on Linux, such as coredns and the VPC resource controller.
