HAQM Redshift has launched the ability to run a single-node RA3.xlplus cluster. HAQM Redshift RA3 clusters support many important features including HAQM 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 HAQM 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 HAQM Redshift availability. To learn more about RA3 nodes, see the HAQM Redshift RA3 feature page. To learn more about DS2 to RA3 upgrades, see the Upgrading to RA3 node types section of the HAQM Redshift documentation. You can find more information on pricing by visiting the HAQM Redshift pricing page.
