More efficient and functional workplaces start with smart building data
Smart building data is being used to make buildings more efficient, more responsive, and better
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.
