EKS cluster provisioning with managed node groups, Fargate profiles, or self-managed nodes VPC and networking design including security groups, network policies, and service mesh integration There are two types of node groups in EKS: • Managed node groups are backed by an EC2 Auto scaling group that AWS provisions and manages on your behalf. Update Kubeconfig Syntax: aws eks update-kubeconfig --region region-code --name your-cluster-name Kubernetes has 3 types of autoscaling groups. Both Karpenter and Cluster Autoscaler provide stable solutions for EKS autoscaling, with Karpenter best for high-performance, AWS-native requirements, particularly via EKS Auto Mode.

EKS - Cluster Autoscaler Step-01: Introduction The Kubernetes Cluster Autoscaler automatically adjusts the number of nodes in your cluster when pods fail to launch due to lack of resources or when nodes in the cluster are underutilized and their pods can be rescheduled onto other nodes in the cluster. Design AWS networking solutions (VPC, Transit Gateway, Security Groups, NACLs) Optimize autoscaling using Karpenter / Cluster Autoscaler Support AI/LLM workloads requiring high-compute infrastructure Implement Helm-based Kubernetes deployments Ensure reliability, scalability, cost optimization, and security best practices Required Technical Skills After 7 months of DevOps training, students should build something real, production-style, Tagged with aws, devops, kubernetes, microservices. This guide will provide a mental model for configuring the Cluster Autoscaler and choosing the best set of tradeoffs to meet your organization’s requirements. This article will help automate the process of creating and configuring Cluster Autoscaler and HPA in AWS Elastic Kubernetes Service (EKS). These permissions should be set up following the official Kubernetes Cluster Autoscaler AWS documentation. Cluster Autoscaler Configuration Cluster Autoscaler is a component that automatically adjusts the size of a Kubernetes Cluster so that all pods have a place to run and there are no unneeded nodes. Since worker nodes represent the largest cost component in most EKS deployments, selecting the right instance families and pricing models can dramatically impact your bill. This will allow Cluster Autoscaler and Karpenter to safely drain and evict pods from the under-utilized nodes during a Node scale-down event. Individual instances without Auto Scaling groups The Kubernetes cluster autoscaler is an important component to make sure your cluster does not run out of compute resources. Karpenter takes a different approach. Kubernetes builds upon 15 years of experience of running production workloads at Google, combined with best-of-breed ideas and practices from the community Why AWS Still Wins (Despite GCP's Better Design) Introduction This is a Tagged with aws, gcp, eks, gke. The Kubernetes Cluster Autoscaler is a popular Cluster Autoscaling solution maintained by SIG Autoscaling . , a group of EC2 instances that will run your Kubernetes workloads): The AWS Load Balancer Controller By default Cluster Autoscaler looks up for the EKS certificate in a different location. Kubernetes, also known as K8s, is an open source system for automating deployment, scaling, and management of containerized applications. Cost Optimization for Kubernetes on AWS EC2 spot instances integrate well with EKS through spot instance interruption handling and cluster autoscaler configurations. The nodegroup is managed using Amazon EC2 Auto Scaling group (ASG). TEST and Verification There are two types of nodegroups in EKS, managed nodegroup and Self-managed (also known as unmanaged) nodegroup. You can create a cluster (or nodegroup in an existing cluster) with IAM role that will allow use of cluster autoscaler : If you would like to be able to scale your node group up from 0 and you have labels and/or taints defined on your nodegroups, you will need to propagate these as tags on your Auto Scaling Groups (ASGs). (Note: When an EKS DescribeNodegroup API label and a tag on the underlying autoscaling group have the same key, the EKS DescribeNodegroup API label value will be saved by the Cluster Autoscaler over the autoscaling group tag value. Chapter 16: Working with a Service Mesh20. The "eks:DescribeNodegroup" permission allows Cluster Autoscaler to pull labels and taints from the EKS DescribeNodegroup API for EKS managed nodegroups. 🚀 What Happens When Traffic Suddenly Increases in Amazon EKS? While learning Amazon EKS, I wanted to understand something very practical: 👉 What actually happens inside the cluster when Contents: Complete microservices e-commerce platform 15+ Kubernetes manifests (Deployments, StatefulSets, Services) AWS integration (EKS, ECR, S3, IAM, NLB) Auto-scaling (HPA, VPA, Cluster If AWS terms overwhelm you, this chart will fix it. Cluster Autoscaling (CA). Prerequisites and Execution process Before executing the above script, AWS CLI, kubectl, and eksctl must be installed on the system. This guide provides advice about Cluster Autoscaling, including guidance for Auto Mode, Karpenter and Kubernetes Cluster Autoscaler. 5 things I wish I knew before running EKS in production: ━━━━━━━━━━━━━━━ 1. The AWS Cloud Provider implementation within Cluster Autoscaler controls the . DesiredReplicas field of your EC2 Auto Scaling Groups. When you move from EC2-land to Kubernetes, everything sounds different. For a long time, the official EKS documentation has recommended using the official Kubernetes Cluster Autoscaler. Horizontal Pod Autoscaling(HPA). Monitoring: To monitor the Amazon EKS cluster, AWS CloudWatch and AWS CloudTrail can be used. You will learn to implement robust monitoring solutions with Prometheus and Grafana, and automate scaling of your EKS nodes and applications using Cluster Autoscaler, HPA, and VPA. Roles & Responsibilities Advanced experience with AWS services (EKS, Cognito, Lambda, ALB, IAM, CloudWatch, VPC). This article will not address tuning the autoscaler for performance or optimizing your cluster for cost. Cluster Autoscaler configure on AWS EKS By referring to the AWS EKS documentation, you can configure resource requests and limits for Kubernetes using VPA and Goldilocks. e. Your 10% EKS optimized AMIs include configurations that reduce overhead, but custom AMIs let you strip unused components for additional savings. . The Cluster Autoscaler will automatically modify your node groups so that they scale out when you need more resources and scale in when you have underutilized resources. It covers provider selection, credential management, provider-specific configurat Chapter 14: Setting Load Balancing for Applications on EKS18. May 1, 2025 · EKS Cluster Autoscaler: Autoscaling on AWS Even managed Kubernetes usually doesn’t have built-in autoscaling out-of-the-box. Defines a Managed Node Group for the EKS cluster (i. Cluster-Autoscaler | Amazon EKS Deploy cluster-autoscaler on your EKS cluster Autoscaling is a function that automatically scales resources up or down to meet inconsistent demands. Managed node groups are tagged so that they work with the cluster autoscaler (that you'll have to deploy to the EKS cluster yourself).
