Amazon Redshift Concurrency Scaling is now available in three additional regions

Amazon Redshift Concurrency Scaling is now available in the AWS Europe (Zurich), Europe (Spain), and Middle East (UAE) regions.

Amazon Redshift Concurrency Scaling 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. Amazon Redshift customers with an active Redshift cluster earn up to one hour of free Concurrency Scaling credits, which is sufficient for the concurrency needs of most customers. Concurrency scaling allows you to specify usage control providing customers with predictability in their month-to-month cost, even during periods of fluctuating analytical demand.

To enable Concurrency Scaling, set the Concurrency Scaling Mode to Auto in your Amazon Web Services Management Console. 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.
