What is eks in aws

Last updated: April 1, 2026

Quick Answer: EKS (Elastic Kubernetes Service) is AWS's fully managed Kubernetes service that simplifies running Kubernetes clusters without managing the control plane yourself, allowing you to focus on containerized applications at scale.

Key Facts

Overview

Amazon Elastic Kubernetes Service (EKS) is a managed container orchestration service that runs Kubernetes on AWS. It eliminates the need to install, operate, and maintain your own Kubernetes control plane or nodes. With EKS, you get a secure, scalable, and highly available Kubernetes environment for running containerized applications.

How EKS Works

EKS manages the Kubernetes control plane components across multiple availability zones for high availability. Your cluster runs on your own EC2 instances or through AWS Fargate, which is a serverless compute engine. The service automatically patches and updates your control plane, ensuring security and compliance without any action required on your part.

Key Features

Common Use Cases

EKS is ideal for organizations running microservices, containerized applications, and complex distributed systems. Companies use EKS for continuous deployment pipelines, machine learning workloads, and applications requiring high availability and automatic scaling. It's particularly useful for organizations already invested in the AWS ecosystem.

Pricing Considerations

EKS charges a per-cluster management fee regardless of cluster size. Additional costs include EC2 instances for your nodes or Fargate compute resources. Data transfer, storage, and other AWS services incur separate charges. Organizations should monitor usage to optimize costs.

Related Questions

What's the difference between EKS and self-managed Kubernetes?

EKS is fully managed by AWS with automatic patching and high availability, while self-managed Kubernetes requires you to handle control plane maintenance, updates, and availability. EKS reduces operational overhead significantly.

What is the difference between EKS and EC2?

EC2 provides virtual machines where you manage everything including operating system and application installation. EKS is a Kubernetes service that automates container orchestration and deployment. EKS typically requires less operational management for containerized workloads.

Can I use both EC2 and Fargate in the same EKS cluster?

Yes, you can run a hybrid EKS cluster with both EC2 nodes and Fargate pods. This flexibility allows you to optimize costs and resource usage for different workload types.

What is EKS vs ECS for container orchestration?

ECS is AWS's proprietary container orchestration service, while EKS is AWS's managed Kubernetes service. EKS uses standard Kubernetes making applications portable, while ECS is AWS-specific. Choose EKS for Kubernetes compatibility, ECS for AWS-native simplicity.

How much does EKS cost?

EKS charges $0.10 per cluster per hour, plus costs for EC2 instances or Fargate compute. Exact pricing depends on your infrastructure choices and region.

How much does Amazon EKS cost?

EKS charges per cluster per hour (approximately $0.10/hour per cluster) plus EC2 or Fargate compute costs for running containers. Total costs depend on cluster size, data transfer, and storage usage. AWS pricing calculator can estimate costs for your specific usage pattern.
