<p>can I scale up (add more nodes) my Kubernetes cluster in AWS via AWS Auto Scaling Group only or I must use <code>kops</code> for this purpose as well? I used <code>kops</code> to provision Kubernetes cluster in the first place.</p>

<p>You definetly you can scale up in aws EKS using aws auto scaling group.</p>

<p>cluster auto-scaler will automatically add the node in pool when there is insufficient memory for pod or there fails to assign new pod on node.</p>

<p>for more help you can refer this document : <a href="https://medium.com/@alejandro.millan.frias/cluster-autoscaler-in-amazon-eks-d9f787176519" rel="nofollow noreferrer">https://medium.com/@alejandro.millan.frias/cluster-autoscaler-in-amazon-eks-d9f787176519</a></p>
