Amazon RDS Proxy announces support for end-to-end IAM authentication

Amazon Relational Database Service (RDS) Proxy now supports end-to-end IAM authentication for connections to Amazon Aurora and RDS database instances. This feature allows you to connect from your applications to your databases through RDS Proxy using AWS Identity and Access Management (IAM) authentication. End-to-end IAM authentication simplifies credential management, reduces credential rotation overhead, and enables you to leverage IAM's robust authentication and authorization capabilities throughout your database connection path.

With end-to-end IAM authentication, you can now connect to your databases through RDS Proxy without needing to register or store credentials in Secrets Manager. End-to-end IAM authentication is available for MySQL and PostgreSQL database engines in all AWS Regions where RDS Proxy is supported.

Many applications, including those built on modern serverless architectures, may need to have a high number of open connections to the database or may frequently open and close database connections, exhausting the database memory and compute resources. Amazon RDS Proxy allows applications to pool and share database connections, improving your database efficiency and application scalability. RDS Proxy helps improve application scalability, resiliency, and security.

For information on supported database engine versions and regional availability of RDS Proxy, refer to our RDS and Aurora documentations.
