There are many choices to make when considering storage in Amazon Elastic Kubernetes Service (EKS). This lab walks through some of the fundamental choices you have in Kubernetes when it comes to data persistence. For workloads requiring persistent storage managed directly in EKS, there are several AWS storage services that can be integrated, including:

• Amazon Elastic Block Store (EBS)
• Amazon Elastic File System (EFS)
• Amazon FSx

This lab discusses the capabilities of each and demonstrates how to use EBS and EFS storage within EKS.

To implement the storage integrations, you will augment a cloud-native EKS application deployed using Terraform. Patches are progressively applied using Terraform to adapt the application to use different AWS storage services first-hand.

Learning objectives

Upon completion of this intermediate-level lab, you will be able to:

• Understand the various AWS storage services that integrate directly with EKS and when to use them
• Use Terraform to deploy different AWS storage service solutions in EKS
• Learn how Kubernetes resources, such as PersistentVolumes, PersistentVolumeClaims, and StatefulSets, are used to manage storage in EKS

Intended audience

• Cloud Architects
• DevOps Engineers
• Kubernetes Practitioners

Prerequisites

Familiarity with the following is beneficial:
