Amazon Redshift launches RA3.4xlarge nodes with managed storage
Starting today, Amazon Redshift RA3.4xlarge nodes are generally available. These new node types support up to 64 TB of Redshift managed storage per node. They enable you to scale and pay for compute and storage independently, allowing you to size your cluster based only on your compute needs.

Previously, we launched the now popular RA3.16xlarge nodes for the largest workloads with 48vCPUs, 384 GiB of memory, and support for up to 64TB of Redshift managed storage per node. RA3.4xlarge nodes offer one-fourth compute (12 vCPU), and memory (96 GiB) compared to RA3.16xlarge at one-fourth of the price. By choosing the RA3 node size and number of nodes, you can now provision the right amount of compute for your workload.
RA3 nodes are built on the AWS Nitro System and feature high bandwidth networking and 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 the AWS Management Console or the create cluster API. To upgrade 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 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 Asia Pacific (Seoul, Singapore, Sydney, Tokyo), Brazil (São Paulo), Canada (Central), EU (Frankfurt, Ireland, London, Paris), US East (N. Virginia, Ohio), and US West (N. California, Oregon) regions.
