You pay the same low rate for RMS regardless of whether the data resides in high-performance SSDs or in Amazon S3. If the data in a node grows beyond the size of the large local SSDs, RMS automatically offloads that data to Amazon S3. Redshift Managed Storage (RMS) uses large, high-performance solid-state drives (SSDs) in each RA3 node for fast local storage and Amazon Simple Storage Service (Amazon S3) for longer-term durable storage. You should size your RA3 cluster based on the amount of data you process daily. With RA3, you choose the number of nodes based on your performance requirements and pay only for the managed storage you use. RA3 nodes with managed storage allow you to optimize your data warehouse by scaling and paying for compute and managed storage independently. Amazon Redshift Serverless automatically provisions the appropriate resources required to service the workload so you don’t need to choose a node type. For dynamic workloads, you can use Concurrency Scaling to automatically provision additional compute capacity and pay only for what you use on a per-second basis after exhausting the free credits (see Concurrency Scaling pricing).Īmazon Redshift offers different node types to accommodate your workloads, and we recommend choosing RA3 or DC2 depending on the required performance, data size, and growth. With Resize Scheduler, you can add and remove nodes on a daily or weekly basis to optimize cost and get the best performance. Once you make your selection, you may wish to use Elastic Resize to easily adjust the amount of provisioned compute capacity within minutes for steady-state processing. You’ll see on-demand pricing before making your selection, and later you can purchase reserved nodes for significant discounts. You can quickly scale your cluster, pause and resume the cluster, and switch between node types with a single API call or a few clicks in the Redshift console. What to expect with provisioned Amazon Redshift:įirst, learn more about node types so you can choose the best cluster configuration for your needs. Alternatively, Amazon Redshift Serverless allows you to pay for usage by automatically starting up, shutting down, and scaling capacity up or down based on your application's needs, so you pay only for capacity consumed while processing the workload. With provisioned Amazon Redshift, you can choose On-Demand Instances and pay for your database by the hour with no long-term commitments or upfront fees, or choose Reserved Instances for additional savings. Choose what is right for your business needs, with the ability to grow storage without over-provisioning compute or storage. With Amazon Redshift, you can start small at $0.25 per hour and scale up to petabytes of data and thousands of concurrent users.
