Real-Life Use Cases with Examples 🌟

1. Dynamic Secrets for Cloud Providers: Vault can generate temporary AWS IAM credentials. Imagine a scenario where your company's app needs to access AWS S3 buckets securely. Vault can create IAM credentials on-the-fly for the app:

    vault write aws/roles/myapp \
       auth_type=iam \
       bound_iam_principal_arn=arn:aws:iam::123456789012:role/myapp-role
