After your cluster is created, you can find information in this section about regions where features are available, maintenance tasks, node types, and usage limits.

Region and Availability Zone considerations
Amazon Redshift is available in several AWS Regions. By default, Amazon Redshift provisions your cluster in a randomly selected Availability Zone (AZ) within the AWS Region that you choose. All the cluster nodes are provisioned in the same Availability Zone.
You can optionally request a specific Availability Zone if Amazon Redshift is available in that zone. For example, if you already have an Amazon EC2 instance running in one Availability Zone, you might want to create your Amazon Redshift cluster in the same zone to reduce latency. On the other hand, you might want to choose another Availability Zone for higher availability. Amazon Redshift might not be available in all Availability Zones within an AWS Region.
For a list of supported AWS Regions where you can provision an Amazon Redshift cluster, see Amazon Redshift endpoints in the Amazon Web Services General Reference.
