The new RG instances offer up to 2.4x faster query performance than previous RA3 instances at about 30% lower cost per vCPU. They provide options to right-size clusters according to workload demands. These instance sizes are available on the current Amazon Redshift track, while older instance types remain supported on the trailing track.
Customers can migrate existing RA3 clusters to RG instances using familiar methods like snapshot restore or resize operations. The RG instances support flexible pricing including On-Demand and Reserved Instances with no upfront payment, and are available across many global regions.
