A couple things to unpack here as there is both Node Autoscaling and (Horizontal) Pod Autoscaling.
On Node Groups yes, but you’ll need to create your and manage your own AMIs. Using a CNI other than the Amazon VPC CNI plug-in may also mean you are responsible for debugging any pod networking issues that crop up.
Once the Fargate Profile is created, when you create a pod, if the namespace of the pod matches one of the namespaces in the Fargate Profile, then it will result in a Fargate worker node being created and the pod placed on the worker.
Sadness. Your pod will be stuck in a pending state. Forever. Stuck in a perpetual Yay, welcome to Ground Hog Day, 2020 edition.
I hope this answered some of your initial questions on EKS, Fargate, and Node Groups. If you think I’ve missed something please ask in the comments section below!

EKS is a managed service that makes it easy to deploy, manage, and scale containerized applications using Kubernetes on AWS. EKS runs up-to-date versions of the open-source Kubernetes software, so you can use all the existing plugins and tooling from the Kubernetes community. EKS is also integrated with many AWS services to provide a rich and seamless experience for running your containerized workloads.
Service discovery is a method of automatically identifying and configuring the services that are running on a network. This can be done through a variety of means, such as by using a central repository that stores information about the services that are available, or by using a broadcast mechanism that allows services to announce their presence to other devices on the network.
EKS provides a managed Kubernetes service, which means that you don’t have to worry about installing, configuring, and maintaining your own Kubernetes cluster. This can save you a lot of time and effort, particularly if you’re not already familiar with Kubernetes. In addition, EKS is integrated with other AWS services, which can make it easier to set up and manage your containerized applications.
You will need to configure your VPC in order to allow communication between your EKS cluster and your worker nodes. You will also need to create a security group for your EKS cluster that will allow traffic from your worker nodes. Finally, you will need to create subnets for your EKS cluster in order to allow communication between your EKS cluster and the internet.
What is Amazon EKS?
As we know that containers were always there, we call them Docker in the current time. Amazon Elastic Kubernetes Service has simplified the use of Kubernetes on AWS/Cloud hence removing the effort of setting it up on a personal control-plane. It takes care of upgrades & patching.
EKS – Cloud Trail are together used to track user and cluster activity. Cloud Trail captures the API calls coming to EKS.
Logs for K8s can be seen in Amazon CloudWatch.
Running clusters can be updated without removing old clusters or creating new clusters. It offers compatibility with add-ons like CoreDNS used to create DNS service, web-based UI called Kubernetes Dashboard and kubectl a utility used to access and manage clusters. Control plane in K8s knows how talking happens between K8s and cluster:
