Managing long-lived credentials in a multicloud environment is a primary source of architectural fragility and security debt. When an application hosted on Microsoft Azure needs to access a private Amazon Web Services resource, such as an S3 bucket or a DynamoDB table, engineering teams often resort to creating IAM users with static access keys. These keys are frequently hardcoded, inadequately rotated, or leaked through insecure CI/CD pipelines, leading to unauthorized data egress and compromised compliance postures (Humble & Farley, 2010). The definitive solution to this vulnerability is Workload Identity Federation using OpenID Connect (OIDC). By establishing a trust relationship between the Azure Active Directory (now Microsoft Entra ID) and the AWS Identity and Access Management (IAM) control plane, we eliminate the need for static secrets entirely.…
