AWS CloudFormation now supports Amazon Relational Database Service (Amazon RDS) Multi-AZ deployments with two readable standbys. AWS CloudFormation speeds up cloud provisioning with infrastructure as code. You can use AWS CloudFormation templates to deploy and modify Amazon RDS Multi-AZ deployments with two readable standbys, along with the rest of your AWS infrastructure, in a secure, efficient, and repeatable manner.

Amazon RDS Multi-AZ deployments provide enhanced availability and durability, making them a natural fit for production database workloads. Deployment of Amazon RDS Multi-AZ with two readable standbys supports up to 2x faster transaction commits than a Multi-AZ deployment with one standby instance. In this configuration, automated failovers typically take under 35 seconds. In addition, the two readable standbys can also serve read traffic without needing to attach additional read replicas.

For a full list of the Amazon RDS Multi-AZ with two readable standbys regional availability and supported engine versions, refer to the Amazon RDS User Guide.

Create or update a fully managed Amazon RDS Multi-AZ database with two readable standby instances in the Amazon RDS Management Console or by using CloudFormation.
