RA3 node types come in three different sizes to accommodate your analytical workloads. RA3 nodes use your workload patterns and advanced data management techniques to deliver the performance of local SSD while scaling storage automatically to Amazon Simple Storage Service (Amazon S3). RA3 nodes are built on the AWS Nitro System and feature high bandwidth networking and large high-performance SSDs as local caches. When you use the RA3 node size and choose your number of nodes, you can provision the compute independent of storage. If you’re using the DS2 node type, we strongly recommend that you upgrade to RA3 to get twice as much storage and improved performance for the same on-demand cost. Dense storage (deprecated) – DS2 nodes enable you to create large data warehouses using hard disk drives (HDDs).You choose the number of nodes you need based on data size and performance requirements. Dense compute – DC2 nodes enable you to have compute-intensive data warehouses with local SSD storage included.Other node types that we previously offered include the following: RA3 architecture gives you the ability to size your cluster based on the amount of data you process daily or the amount of data that you want to store in your warehouse there is no need to account for both storage and processing needs together. With RA3, you choose the number of nodes based on your performance requirements and only pay for the managed storage that you use. RA3 node types are the latest node type for Amazon Redshift. RA3 nodes with managed storage enable you to optimize your data warehouse by scaling and paying for compute and managed storage independently. In this post, we cover the current generation node RA3 architecture, different RA3 node types, important capabilities that are available only on RA3 node types, and how you can upgrade your current Amazon Redshift node types to RA3. The node type determines the CPU, RAM, storage capacity, and storage drive type for each node. While launching a provisioned cluster, one option that you specify is the node type. Creating an Amazon Redshift cluster is the first step in your process of building an Amazon Redshift data warehouse. Each cluster runs the Amazon Redshift engine and contains one or more databases. When spinning up a new instance of Amazon Redshift, you get to choose either Amazon Redshift Serverless, for when you need a data warehouse that can scale seamlessly and automatically as your demand evolves unpredictably, or you can choose an Amazon Redshift provisioned cluster for steady-state workloads and greater control over your Amazon Redshift cluster’s configuration.Īn Amazon Redshift provisioned cluster is a collection of computing resources called nodes, which are organized into a group called a cluster. This latest generation powers the several modern data architecture patterns our customers are actively embracing to build flexible and scalable analytics platforms. In its latest offering, Amazon Redshift runs on third-generation architecture where storage and compute layers are decoupled and scaled independent of each other. Support for Amazon Redshift Spectrum compute nodes was later added to extend your data warehouse to data lakes, and the concurrency scaling feature was added to support burst activity and scale your data warehouse to support thousands of queries concurrently. Its journey started as a standalone data warehousing appliance that provided a low-cost, high-performance, cloud-based data warehouse. Over the years, Amazon Redshift has evolved a lot to meet our customer demands. This enables you to use your data to acquire new insights for your business and customers. You can start with just a few hundred gigabytes of data and scale to a petabyte or more. Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud.
