There are no mentions in documentation. I assume that it is virtually unlimited within common sense. You just need to justify a need to increase that limit, when you make a request to AWS Support.

    Thanks for the info . Is there any performance issue found after certain number node groups ? Does a large number of groups require any specific configuations to maintain ?

    I guess, the main question is not "how many node groups you have", it's about "how many nodes" I know that thousands of nodes work in EKS. You just need to make sure that you have enough IPs in your subnets.

    If you need different node groups for different applications/workloads, you just need to add appropriate labels, taints and tolerations.
