Amazon RDS Multi-AZ deployment with two readable standbys now supports AWS IAM database authentication

Amazon Relational Database Service (Amazon RDS) Multi-AZ deployments with two readable standbys now supports using AWS Identity and Access Management (IAM) for database authentication. With IAM support, you can now centrally manage access to your RDS Multi-AZ deployments with two readable standbys along with other RDS deployments, instead of managing access individually. In addition, AWS IAM eliminates the need for storing password-based login credentials in the database.

Amazon RDS Multi-AZ deployments with two readable standbys is ideal when your workloads require lower write latency and more read capacity. This deployment option also supports minor version upgrades and system maintenance updates with typically less than one second of downtime when using Amazon RDS Proxy or open source tools such as AWS Advanced JDBC Driver, PgBouncer, or ProxySQL.
