Using static credentials for accessing AWS resources from Google Cloud poses significant security risks. Dynamic, short-lived credentials via OIDC Federation provide a solution that eliminates the need for manual key rotation. By integrating AWS and GCP services with automatic credential refresh, this method enhances security and reduces complexity in multi-cloud environments. The post details a practical implementation using AWS SDK, Kubernetes, and Terraform.
