What are the differences between an AWS Autoscaling Group and an AWS EKS managed node group for use with an EKS cluster?

Sources

Answer

An AWS Autoscaling Group and an AWS EKS managed node group are both used for automatic scaling and management of EC2 instances in an EKS cluster. However, there are some differences between them. An Autoscaling Group is a collection of EC2 instances that are treated as a logical grouping for the purposes of automatic scaling and management
1
. It lets you use Amazon EC2 Auto Scaling features such as health check replacements and scaling policies. On the other hand, an EKS managed node group automates the provisioning and lifecycle management of nodes for your Kubernetes clusters
2
. It provides an abstraction to Amazon EC2 instances and Auto Scaling groups, enabling a set of simple one-step operations in EKS to provision and manage groups of cluster nodes. It is compatible with the Cluster Autoscaler and is backed by EC2 instances in your account which are managed by an Auto Scaling group
