In continuation of our Part 1 of our blog introducing Pod Identity vs. IRSA for Amazon EKS, and Part 2, where we explored how to use Amazon EKS Pod Identity with the Rafay platform, this is Part 3 of the blog post. It will guide you through the migration of existing IRSA to Pod Identity using Rafay.
When managing containerized applications on Amazon Elastic Kubernetes Service (EKS), a critical concern is securely granting permissions to your applications so that they can securely access AWS resources. Traditionally, AWS has provided mechanisms like IAM Roles for Service Accounts (IRSA) to enable fine-grained permissions management within EKS clusters. However, EKS Pod Identity, a newer feature, offers a more refined and efficient solution.
In this blog, we’ll explore how EKS Pod Identity differs from IRSA, and why it represents a significant improvement for identity management in Amazon EKS based environments. Let's assume our EKS cluster resident application needs to securely access data in an AWS s3 bucket.
