Amazon Elastic Kubernetes Service – Definition & Overview

Amazon Elastic Kubernetes Service – Definition & Overview


Amazon Elastic Kubernetes Service is a wholly managed service that Amazon Web Services (AWS) offers. Kubernetes is an open-source container planning platform that automates the deployment, scaling & management of containerized applications.

Furthermore, Amazon EKS shortens the process of running Kubernetes on AWS by controlling the heavy lifting associated with cluster setup, scaling, and maintenance.

How Does Amazon Elastic Kubernetes Service Work?

Amazon Elastic Kubernetes Service simplifies Kubernetes deployment on AWS by managing the control plane and automating key operational tasks. Users create an EKS cluster, stating the desired configuration.

Additionally, EKS provisions the required AWS resources, including compute instances, networking, and storage. The managed control plane is distributed across multiple Availability Zones for high availability.

However, users deploy containerized applications onto the cluster, and EKS automates load balancing, scaling, and self-healing. AWS services like IAM, VPC, and KMS boost security. EKS seamlessly integrates with other AWS, creating a scalable and secure platform for handling Kubernetes workloads without the complexities of manual management.

Two Components of Amazon Elastic Kubernetes Service:

Amazon Elastic Kubernetes Service contains two main components:

  1. Control Plane:

It is the central management component of Amazon EKS. It controls the Kubernetes cluster, including scheduling, scaling, and maintaining the applications’ desired state. In addition, Amazon EKS manages this control plane, ensuring its high availability and security.

  1. Worker Nodes:

These are instances in the Amazon EKS cluster operating the containerized applications. These nodes are part of an Amazon EC2 Auto Scaling group, enabling automatic scaling based on the workload.

Users can customize these worker nodes based on their application requirements, and the nodes communicate with the EKS control plane to receive instructions and updates. Worker nodes run the Kubernetes Kubelet, which manages containers on each node and communicates with the control plane to ensure the applications’ desired state.

Key Features and Aspects of Amazon Elastic Kubernetes Service:

Key features and aspects of Amazon EKS include:

  1. Managed Kubernetes Control Plane:

Amazon EKS manages the Kubernetes control plane, ensuring it is highly available, securely configured, and up-to-date.

  1. Easily Deploy and Scale Applications:

Users get to deploy, manage, and scale containerized applications using Kubernetes on AWS without managing the underlying infrastructure.

  1. Integration with AWS Services:

EKS seamlessly integrates with other AWS services, letting users leverage additional AWS features such as Amazon EC2, Amazon RDS, AWS Identity and Access Management (IAM), and more.

  1. Security:

It heightens security by leveraging AWS IAM for authentication, VPC (Virtual Private Cloud) for network isolation, and AWS Key Management Service (KMS) for encryption. Therefore, it ensures a secure environment for running containerized applications.

Benefits of Amazon Elastic Kubernetes Service:

Amazon Elastic Kubernetes Service offers numerous benefits for organizations pursuing to deploy and manage containerized applications using Kubernetes on the AWS cloud:

  1. Managed Control Plane:

Amazon EKS provides a fully managed Kubernetes control plane, removing the operational overhead of maintaining and scaling the control plane. AWS handles the control plane’s availability, security, and updates.

  1. Security Integration:

Amazon EKS integrates with AWS Identity and Access Management (IAM) for authentication and authorization. It leverages Amazon VPC for network isolation, increasing the overall security of the Kubernetes environment.

  1. Easy Cluster Management:

Users can create, update, and manage Kubernetes clusters using known tools and Kubernetes APIs. EKS shortens cluster management tasks, making it easier for organizations to implement and operate Kubernetes.

  1. Automated Updates:

It automates updating the Kubernetes control plane, decreasing the operational burden on users. Therefore, it ensures that the cluster stays up-to-date with the latest security patches and updates.

  1. Cost Efficiency:

Elastic Kubernetes Service allows organizations to adjust costs by automatically scaling worker nodes based on the application’s demand. Users can leverage Amazon EC2 Spot Instances to decrease compute costs further.


In conclusion, Amazon Elastic Kubernetes Service is a keystone in AWS’s container orchestration offerings, providing a fully managed and scalable Kubernetes environment. With a managed control plane, EKS discharges users of operational complexities, ensuring high availability, security, and seamless updates.

In addition, its integration with AWS services enriches flexibility and compatibility, while features like automatic scaling and security integration streamline cluster management. EKS authorizes organizations to proficiently deploy, scale, and manage containerized applications, fostering innovation without infrastructure maintenance overhead.

As a result, EKS arises as a robust solution for enterprises seeking a reliable and accessible platform for Kubernetes-based workloads.
