Amazon Redshift has launched the ability to run a single-node RA3.xlplus cluster. Amazon Redshift RA3 clusters support many important features including Amazon Redshift Managed Storage (RMS), data sharing and AQUA. Single-node RA3.xlplus clusters allow you to take advantage of the most advanced Redshift features at a lower cost. You can migrate single-node DS2.xlarge or single-node DC2.large clusters to single-node RA3.xlplus clusters as part of a cross-instance Classic Resize function. You can also use cross-instance Classic Resize as part of the Reserved Instance (RI) Migration feature in the Amazon Redshift Console, CLI or API to migrate your single-node DS2.xlarge RI clusters to RA3.xlplus RI clusters without changes to the RI contract’s start or end dates and without incurring additional charges.

Single-node RA3.xlplus clusters are now available in all commercial AWS Regions. Refer to the AWS Region Table for Amazon Redshift availability. To learn more about RA3 nodes, see the Amazon Redshift RA3 feature page. To learn more about DS2 to RA3 upgrades, see the Upgrading to RA3 node types section of the Amazon Redshift documentation. You can find more information on pricing by visiting the Amazon Redshift pricing page.
