Manage access to your RDS for MySQL and Amazon Aurora databases using AWS IAM

Starting today, Amazon RDS enables you to use AWS Identity and Access Management (IAM) to manage database access for Amazon RDS for MySQL DB instances and Amazon Aurora DB clusters. Database administrators can now associate database users with IAM users and roles. By using IAM, you can manage user access to all AWS resources from a single location, avoiding issues caused by permissions that are out of sync on different AWS resources.
