Billing strategy – on-demand billing or a reserved pricing strategy.The region where the cluster is deployed.The node type that the customer chooses to build his cluster. ![]() Redshift Pricing is broadly affected by four factors: An hour of concurrency scaling comes free for every 24 hours a Redshift cluster stays operational. Redshift’s concurrency scaling allows one to scale at times where a higher load is anticipated. It can query data stored in S3 or other storage services. Redshift spectrum helps one to exploit Redshift querying abilities on data that is not stored Redshift table. Tasks are usually query processes that deal with the chunk of the data that is handled by the particular worker node.īeyond the superfast querying abilities and virtually unlimited storage through horizontal scaling, Redshift offers many other features. Secondary nodes or worker nodes are responsible for actually executing the tasks. Leader nodes handle client communication, query strategy, and assign tasks to the worker nodes. Redshift is designed as a collection of instances that are designated as a leader or worker node. On the other hand, customers with heavy processing requirements can configure it with dense compute instances that are made of SSDs. For example, customers with storage heavy workload and wants to keep the costs down can use Redshift’s dense storage nodes that are made of HDDs. Redshift clusters can be configured for different kinds of workloads as per the requirement. Under its hood, Redshift has a massively parallel processing architecture.
