In this blog, we explore how to securely authenticate AWS workloads (EC2 or Lambda) to Azure Functions using Microsoft Entra ID Workload Identity Federation. We begin with an overview of identity federation and its role in enabling secure cross-cloud access, then walk through a step-by-step setup for service-to-service authentication. This approach removes the need for storing secrets and demonstrates a modern, secure authentication pattern across AWS and Azure.
