Starting with Amazon EKS: A Simplified Guide for New Users

With EKS, you can manage, deploy, and scale containerized applications using Kubernetes while benefiting from Amazon Web Services (AWS) cloud infrastructure. For businesses and developers looking to leverage Kubernetes without the hassle of managing their clusters, EKS is a perfect choice. This simplified guide covers the basics of Amazon EKS, including what it is, how it works, and what you need to get started. By the end, you’ll better understand deploying your applications with Amazon EKS.

What is Amazon EKS?

Amazon EKS (Elastic Kubernetes Service) is a managed service that makes it easier to run Kubernetes clusters on AWS without installing and operating your own Kubernetes control plane. Kubernetes, an open-source system, automates containerized applications’ deployment, scaling, and management. EKS manages the Kubernetes control plane so developers can focus on deploying and managing their applications, not the underlying infrastructure, which you can learn more about from cloud experts. With EKS, AWS handles the operational complexities of Kubernetes, such as cluster setup, patching, upgrading, and security management. This frees you up to focus on your applications rather than the infrastructure.

Key Concepts to Understand Before Using EKS

Before diving into EKS, it’s essential to understand a few core concepts of Kubernetes and how they relate to EKS:

• Cluster: A Kubernetes cluster has at least one master (control plane) and multiple worker nodes where your application containers run. EKS manages the control plane, and you are responsible for the worker nodes.
• Node: A node runs containerized applications. In EKS, these nodes are often Amazon EC2 instances, but AWS Fargate can also be used for serverless deployment.
• Pod: A pod is a group of containers that share resources and are deployed together.
• Service: A service in Kubernetes exposes an application running on a set of pods that can be accessed internally or externally.
• Namespace: Namespaces in Kubernetes allow you to create isolated environments within the same cluster, helping with organization and resource management.

How to Get Started with Amazon EKS

Step 1: Prerequisites

Before you start using EKS, you’ll need a few tools and prerequisites. If you don’t already have one, sign up for an AWS account. The AWS Command Line Interface (CLI) is a tool for managing your AWS services from the command line. “kubectl” is Kubernetes’ command-line tool used to interact with the Kubernetes API server. At the same time, “eksctl” is a command-line tool for managing EKS clusters. Once you have these tools installed, you’re ready to begin.

Step 2: Create an EKS Cluster

Amazon EKS allows you to create clusters easily using the AWS Management Console, AWS CLI, or “eksctl“. The creation process can take several minutes. Once the cluster is up and running, “eksctl” will automatically configure “kubectl” for you.

Step 3: Deploy Applications on the EKS Cluster

Then, you can start deploying containerized applications. Kubernetes will automatically provision an AWS Elastic Load Balancer (ELB) to route traffic to your service. The external IP address will allow you to access your Nginx application via a web browser.

Step 4: Monitor and Scale Your Applications

One critical advantage of Kubernetes and EKS is that they can scale your applications as demand grows. Use the “kubectl” commands to monitor the status of your pods and nodes.

Step 5: Clean Up Resources

Clean up your resources once you’re done with your experiments or applications to avoid unnecessary costs.

Amazon EKS is a powerful tool for developers and businesses looking to leverage Kubernetes. This guide taught you the basics of setting up and running an EKS cluster. Whether you’re new to Kubernetes or cloud computing in general, EKS simplifies the entire process and provides an excellent entry point for scaling applications on AWS. Now, you’re ready to explore more advanced features, such as monitoring, scaling, and securing your applications in Amazon EKS!
