Amazon EKS and Windows support

When planning to have a heterogenous Amazon EKS cluster, it is imperative to understand what limitations are applied to Windows-based nodes and how that would affect your Amazon EKS cluster.

One of the most common mistakes I’ve seen is customers first adding Windows-based node groups in their Amazon EKS cluster for the next plan on what to do regarding logging, monitoring, security, patching, and EKS limitations. This mistake usually costs lots of money and hours for customers paying hourly rates to consult companies to implement these projects. All these should be planned ahead of time, identifying commercial or open source tools that will address your requirements.

I will discuss some of the most common solutions that don’t fit on Windows-based node groups right from the shelf, which will require additional development to get up and running:

Karpenter: Not available for Windows-based nodes. If you need to use a tool that automatically adjusts the size of your Kubernetes cluster based on the following conditions:Pods that failed to run in the cluster due to insufficient resources, such as IPv4 node exhaustion, as mentioned in the previous topic

Nodes in the cluster that have been underutilized for an extended period of time and their pods can be placed on other existing nodes
