AWS account requirements
When the Cloudera Data Warehouse service is deployed, it uses the AWS VPC that is registered for an environment in the CDP Management Console. Then you use that environment to create Database Catalogs and Virtual Warehouses in the Data Warehouse service. Data Warehouse service has the same AWS requirements as those listed for environments in the Management Console documentation set, which the below Related Information links point to.
Although, the Data Warehouse service uses CDP environments, it creates its own AWS public cloud resources, such as S3 buckets, DynamoDB tables, and IAM roles and policies.
