# Create a zero-ETL integration for Aurora
<a name="zero-etl-setting-up.create-integration-aurora"></a>

In this step, you create an Aurora zero-ETL integration with Amazon Redshift.

**To create an Aurora zero-ETL integration with Amazon Redshift**

1. From the Amazon RDS console, [create a custom DB cluster parameter group](https://docs.amazonaws.cn/AmazonRDS/latest/AuroraUserGuide/zero-etl.setting-up.html#zero-etl.parameters) as described in the *Amazon Aurora User Guide*.

1. From the Amazon RDS console, [create a source Amazon Aurora DB cluster](https://docs.amazonaws.cn/AmazonRDS/latest/AuroraUserGuide/zero-etl.setting-up.html#zero-etl.create-cluster) as described in the *Amazon Aurora User Guide*.

1. From the Amazon Redshift console: [Create and configure a target Amazon Redshift data warehouse](zero-etl-setting-up.rs-data-warehouse.md). 
   + From the Amazon CLI or Amazon Redshift console: [Turn on case sensitivity for your data warehouse](zero-etl-setting-up.case-sensitivity.md).
   + From the Amazon Redshift console: [Configure authorization for your Amazon Redshift data warehouse](zero-etl-using.redshift-iam.md).

1. From the Amazon RDS console, [create a zero-ETL integration](https://docs.amazonaws.cn/AmazonRDS/latest/AuroraUserGuide/zero-etl.creating.html#zero-etl.create) as described in the *Amazon Aurora User Guide*.

1. From the Amazon Redshift console or the query editor v2, [create an Amazon Redshift database from your integration](https://docs.amazonaws.cn/redshift/latest/mgmt/zero-etl-using.creating-db.html).

   Then, [query and create materialized views with replicated data](https://docs.amazonaws.cn/redshift/latest/mgmt/zero-etl-using.querying-and-creating-materialized-views.html).
