Amazon Redshift adds rg.large and rg.12xlarge instance sizes in AWS GovCloud (US) Regions

Posted on: Aug 13, 2026

Amazon Redshift now offers rg.large and rg.12xlarge instance sizes for RG instances in the AWS GovCloud (US-West) and AWS GovCloud (US-East) Regions. RG instances deliver better performance, running data warehouse and data lake workloads up to 2.4x as fast as previous generation RA3 instances, at 30% lower price per vCPU. RG instances include Redshift's custom-built vectorized data lake query engine that processes Apache Iceberg and Parquet data on your cluster nodes, enabling you to run SQL analytics across your data warehouse and data lake using a single engine.

rg.large and rg.12xlarge instance sizes are available on patch version P202 and later. Customers can resize existing RG or RA3 clusters to these new instance sizes using Elastic Resize or Classic Resize. Customers with existing RA3 clusters can also upgrade to RG using Snapshot & Restore.

RG instances are available in four instance sizes: rg.large, rg.xlarge, rg.4xlarge, and rg.12xlarge. RG instances are available with flexible pricing options, including On-Demand, and 1-year and 3-year Reserved Instances with All Upfront, Partial Upfront, and No Upfront payment options.
