Amazon EKS — Complete Guide: Production-Ready Kubernetes on AWS
Welcome to the complete Amazon EKS tutorial. This guide takes you from zero to production-ready EKS clusters, covering everything a DevOps or Cloud Engineer needs to know.
Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes service that runs the Kubernetes control plane across multiple AWS Availability Zones. AWS handles the heavy lifting — patching, upgrading, and ensuring high availability of the control plane — so you can focus on deploying and running your applications.
What is Amazon EKS?
Amazon EKS runs upstream, CNCF-conformant Kubernetes. Any application that runs on standard Kubernetes runs on EKS without modification. You get the full Kubernetes ecosystem — Helm, ArgoCD, Prometheus, Istio — backed by AWS’s managed infrastructure.
Key Features:
| Feature | Description |
|---|---|
| Managed Control Plane | AWS runs the API server, etcd, and scheduler across 3 AZs |
| Multiple Compute Options | Managed Node Groups, Self-Managed Nodes, or Fargate (serverless) |
| Deep AWS Integration | VPC networking, IAM authentication, EBS/EFS storage, ALB/NLB load balancing |
| EKS Add-ons | Managed lifecycle for CoreDNS, kube-proxy, VPC CNI, EBS CSI, and more |
| Security | IRSA, Pod Identity, KMS encryption, Security Groups for Pods |
EKS Pricing Overview
| Component | Cost |
|---|---|
| EKS Cluster | $0.10/hour (~$73/month) per cluster |
| EC2 Worker Nodes | Standard EC2 pricing (varies by instance type) |
| Fargate | Per vCPU and memory per second |
| Data Transfer | Standard AWS data transfer rates |
| EKS Extended Support | Additional fee for older K8s versions past standard support |
Tip: The cluster fee is fixed regardless of workload size. Your biggest cost driver is usually EC2 instances and data transfer.
What You’ll Learn
By the end of this tutorial, you’ll be able to:
- Create and manage EKS clusters using eksctl and Terraform
- Design production VPC architectures for EKS
- Configure managed node groups, Fargate, and Spot instances
- Deploy and manage workloads with best practices
- Set up EBS, EFS, and FSx storage
- Configure ALB/NLB load balancing with the AWS Load Balancer Controller
- Implement security with IRSA, Pod Identity, RBAC, and encryption
- Set up observability with CloudWatch, Prometheus, and Grafana
- Scale with Cluster Autoscaler, Karpenter, HPA, and KEDA
- Perform cluster upgrades safely
- Build CI/CD pipelines and GitOps workflows
- Optimize costs with Spot instances and Karpenter
- Troubleshoot common EKS issues
- Deploy production-ready EKS clusters with Terraform
Prerequisites
Before you begin, make sure you have:
- AWS Account with admin or power-user IAM access
- Basic Kubernetes knowledge (pods, deployments, services)
- AWS CLI v2 installed and configured
- kubectl installed
- eksctl installed
