Amazon Redshift introduces RA3 nodes with managed storage enabling independent compute and storage scaling
Starting today, Amazon Redshift RA3 nodes with managed storage are generally available. RA3 nodes enable you to scale and pay for compute and storage independently allowing you to size your cluster based only on your compute needs. Now you can analyze even more data cost-effectively.
RA3 nodes are built on the AWS Nitro System and feature high bandwidth networking and performance indistinguishable from bare metal. RA3 nodes use very large, high performance SSDs as local caches. RA3 nodes leverage your workload patterns and advanced data management techniques, such as automatic fine-grained data eviction and intelligent data pre-fetching, to deliver the performance of local SSD while scaling storage automatically to S3. RA3 nodes remain fully compatible with all your existing workloads.
To get started with RA3 nodes, you can create a cluster with RA3 nodes via the AWS Management Console or the create cluster API. To migrate your cluster to an RA3 cluster, you can take a snapshot of your existing cluster and restore it to an RA3 cluster, or do a classic resize from your existing cluster to a new RA3 cluster. To learn more about RA3 nodes, see the cluster management guide. You can find more information on pricing by visiting the Amazon Redshift pricing page.
RA3 nodes are generally available in US East (Ohio), US East (N. Virginia), US West (N. California), US West (Oregon), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), EU (Frankfurt), EU (Ireland), EU (London) regions, and will expand to additional regions in the coming months.
