Custom domain names for client connections

You can create a custom domain name, also known as a custom URL, for both your Amazon Redshift cluster and Amazon Redshift Serverless workgroup. It's an easy-to-read DNS record that routes SQL client connections to your endpoint. You can configure it for an existing cluster or workgroup at any time. It provides several benefits:

  • The custom domain name is a more simple string than the default URL, which typically includes the cluster name or the workgroup name and the region. It's easier to recall and use.

  • You can quickly route traffic to a new cluster or workgroup in a fail-over case, for example. This makes it so clients don't have to make a configuration change when they reconnect. Connections can be re-routed centrally, with minimal disruption.

  • You can avoid sharing private information like a server name in a connection URL. You can hide it in a custom URL.

When you set up a custom domain name using a CNAME, there isn't any additional charge from Amazon Redshift. You may be billed from your DNS provider for a domain name, if you create a new one, but this cost is typically small.
