Amazon Redshift announces Concurrency Scaling: Consistently fast performance during bursts of user activity

Amazon Redshift now automatically and elastically scales query processing power to provide consistently fast performance for hundreds of concurrent queries. Concurrency Scaling resources are added to your Redshift cluster transparently in seconds, as concurrency increases, to process queries without wait time. Once workload demand subsides, Amazon Redshift automatically shuts down Concurrency Scaling resources to save you cost. You can continue to use your existing applications and Business Intelligence tools without any changes.

Concurrency Scaling is free for most Redshift customers. For every 24 hours that your main cluster is in use, you accrue a one-hour credit for Concurrency Scaling. These credits enable you to offset the cost of handling significant variance in your workloads, while ensuring consistently fast performance throughout the course of a day. For any usage that exceeds the accrued free usage credits, you’re billed on a per-second basis based on the on-demand rate of your Amazon Redshift cluster. Refer to the Amazon Redshift pricing for more details.

To enable Concurrency Scaling, simply set the Concurrency Scaling Mode to Auto in the AWS Management Console, as described in the Redshift Cluster Management Guide. You can allocate Concurrency Scaling usage to specific user groups and workloads, control the number of Concurrency Scaling clusters that can be used, and monitor Cloudwatch performance and usage metrics.

Amazon Redshift Concurrency Scaling is available in the US East (N. Virginia), US East (Ohio), US West (Oregon), Asia Pacific (Tokyo) and EU (Ireland) regions starting with build version 1.0.6761, and will expand to additional regions in the coming months.
