In 2026, Amazon Redshift expanded its region-specific offerings by adding large (rg.large) and extra-large (rg.12xlarge) RG instance sizes in AWS GovCloud (US-West and US-East). These instances use a custom vectorized query engine enabling unified data warehouse and lake analytics with up to 2.4 times performance improvement over prior RA3 instances.

The new sizes support flexible scaling through Elastic and Classic Resize and allow RA3 clusters to upgrade via snapshot restore. Multiple pricing options—including On-Demand and reserved plans—enable customers to optimize cost and performance in compliance-focused AWS GovCloud environments.
