![]() ![]() Follow the instructions to enter the properties for cluster configuration.A subset of properties of each cluster is also displayed. This page lists the clusters in your account in the current Region. On the Amazon Redshift console, choose Clusters in the navigation pane.To create a new cluster and configure our IAM role as the default role, complete the following steps: The default IAM role is supported in both Amazon Redshift clusters and Amazon Redshift Serverless (preview). Create a new cluster and set up the IAM default role Then we show you how to use the default role with various SQL commands, and how to restrict access to the role. We also demonstrate how to make an existing IAM role the default role, and remove a role as default. To demonstrate this, first we create an IAM role through the Amazon Redshift console that has a policy with permissions to run SQL commands such as COPY, UNLOAD, CREATE EXTERNAL FUNCTION, CREATE EXTERNAL TABLE, CREATE EXTERNAL SCHEMA, CREATE MODEL, or CREATE LIBRARY. You don’t need to reconfigure default IAM roles every time Amazon Redshift introduces a new feature, which requires additional permission, because Amazon Redshift can modify or extend the AWS managed policy, which is attached to the default IAM role, as required.It avoids the need to use multiple AWS Management Console pages to create the Amazon Redshift cluster and IAM role.It allows users to run SQL commands without providing the IAM role’s ARN.The Amazon Redshift default IAM role simplifies authentication and authorization with the following benefits: When you use the Amazon Redshift console to create IAM roles, Amazon Redshift keeps track of all IAM roles created and preselects the most recent default role for all new cluster creations and restores from snapshots. ![]() End-users can use the default IAM role by specifying IAM_ROLE with the DEFAULT keyword. This policy is used for creating the default IAM role via the Amazon Redshift console. To eliminate the need to specify the ARN for the IAM role, Amazon Redshift now provides a new managed IAM policy AmazonRedshiftAllCommandsFullAccess, which has required privileges to use other related services such as Amazon S3, SageMaker, Lambda, Aurora, and AWS Glue. Most data analysts and data engineers using these commands aren’t authorized to view cluster authentication details. Usually, these roles and accesses are set up by admin users. The Amazon Redshift SQL commands for COPY, UNLOAD, CREATE EXTERNAL FUNCTION, CREATE EXTERNAL TABLE, CREATE EXTERNAL SCHEMA, CREATE MODEL, or CREATE LIBRARY historically require the role ARN to be passed as an argument. The default IAM role simplifies SQL operations that access other AWS services (such as COPY, UNLOAD, CREATE EXTERNAL FUNCTION, CREATE EXTERNAL SCHEMA, CREATE MODEL, or CREATE LIBRARY) by eliminating the need to specify the Amazon Resource Name (ARN) for the IAM role. This post discusses the introduction of the default IAM role, which simplifies the use of other services such as Amazon S3, Amazon SageMaker, AWS Lambda, Amazon Aurora, and AWS Glue by allowing you to create an IAM role from the Amazon Redshift console and assign it as the default IAM role to new or existing Amazon Redshift cluster. For details about IAM roles and how to use them, see Create an IAM role for Amazon Redshift. Historically, this has required some degree of expertise to set up access configuration with other AWS services. This requires you to create an AWS Identity and Access Management (IAM) role and grant that role to the Amazon Redshift cluster. Many features in Amazon Redshift access other services, for example, when loading data from Amazon Simple Storage Service (Amazon S3). Today, tens of thousands of AWS customers use Amazon Redshift to run mission-critical business intelligence dashboards, analyze real-time streaming data, and run predictive analytics jobs. Amazon Redshift offers up to three times better price performance than any other cloud data warehouse, and can expand to petabyte scale. Amazon Redshift is a fast, scalable, secure, and fully managed cloud data warehouse that makes it simple and cost-effective to analyze all your data using standard SQL.
