A
Utilize instance metadata for storing credentials and employ Amazon EventBridge to trigger a Lambda function for simultaneous RDS and metadata updates.
B
Encrypt credentials in an S3 bucket, with EventBridge scheduling a Lambda function for RDS and file updates, incorporating S3 Versioning for rollback.
C
Leverage AWS Secrets Manager for credential storage with automatic rotation and EC2 role-based access.
D
Use AWS Systems Manager Parameter Store for encrypted credential storage, with automatic rotation and EC2 role-based access.
