Amazon Redshift Serverless Now Supports 2-AZ Subnet Configurations

Amazon Redshift Serverless now supports subnet configurations with 2 Availability Zones (AZs) when Enhanced VPC Routing (EVR) is not used. This enhancement simplifies the setup process, as you no longer need 3 AZs in your Amazon VPC subnet network.

Previously, creating an Amazon Redshift Serverless workgroup required 3 AZs in your Amazon VPC subnet network. With this update, you only need 2 AZs when creating or updating workgroups without EVR. This requirement applies regardless of your base RPU size (4 to 1024 RPUs), your workgroup’s RPU usage, or whether AI-driven scaling and optimizations is enabled. This change reduces your operational overhead by eliminating the need to configure an additional AZ when you already have 2 AZs defined in your Amazon VPC subnet network.

The 2-AZ support is available in all commercial AWS regions where Amazon Redshift Serverless is offered.

For detailed information about implementing 2-AZ support in Amazon Redshift Serverless, please consult the Amazon Redshift Serverless documentation.
