The new RA3.xlplus node provides 4 vCPUs and 32 GiB of RAM and addresses up to 32 TB of managed storage. A cluster with RA3.xlplus node-type can contain up to 32 of these instances, for a total storage of 1024 TB (that’s 1 petabyte!). With the new smaller RA3.xlplus instance...
operational databases, and data lakes. It offers different node types to suit various workloads; you can choose from RA3, DC2 and DS2 depending on your needs. RA3 is the latest instance type that allows you to independently
HSM encryption is not supported for DC2 and RA3 node types. HSMs are devices that provide direct control of key generation and management. They provide greater security by separating key management from the application and database layers. Amazon Redshift supports AWS CloudHSM Classic for key manag...
We introduced the RA3 node types in 2019 as a technology that allows the independent scaling of compute and storage. We also described how customers, including Codeacademy, OpenVault, Yelp, and Nielsen, have taken advantage of Amazon Redshift RA3 nodes with managed storage toscale thei...
When you launch a cluster, one option that you specify is the node type. The node type determines the CPU, RAM, storage capacity, and storage drive type for each node. Amazon Redshift offers different node types to accommodate your workloads, and we recommend choosing RA3 or DC2 depending ...
DATA DUDE: OK. But before we do that we have to figure out if we want a dc2-type node or an RA3-type node, though before we do THAT we should determine whether we want a large node or a more expensive extra-large node. BOSS: Great – we’ll do – wait – what’s the differe...

RA3 nodes come with managed SSD storage, which provides a very flexible and cost effective storage solution. 2. Apply Optimizations and Wait After analyzing metrics and optimizing queries (if applicable), you might need to update your cluster’s node type. If this is the case you’ll have ...
Here's how RA3 works. AWS characterizes RA3 as separating compute from storage. While this topology is often associated with elastic computing (where compute instances can be completely turned off when not used), it is used differently here. The RA3 node stays active, but cooler data can be ...
