Could you please make more course content than interview questions

[@Pythoholic]

sure teetan i am working on that

Is this the same for RedhShift rbac does it use IAM or is it separate to just RedShift?

[@Pythoholic]

Amazon Redshift has its own access control mechanism, which is based on RBAC. Redshift's RBAC system allows you to define and manage roles, users, and permissions within the Redshift cluster. You can create different roles, assign privileges to those roles, and then associate users with those roles. This enables you to control access to data and perform administrative tasks within the Redshift environment.
While Redshift has its own RBAC system, it also integrates with AWS IAM for authentication purposes. This means that users can authenticate into the Redshift cluster using their AWS IAM credentials. However, once authenticated, Redshift's access control is managed through its internal RBAC system.
In summary, Redshift's access control is based on RBAC for managing permissions and roles within the Redshift cluster, but it can leverage AWS IAM for authentication of users into the cluster. IAM and Redshift RBAC are separate mechanisms but can work together to provide a comprehensive access control solution.

@@Pythoholic thank you for that. One last question. When a user is given access to redshift through iam would his user be created in redshift by default with the same name or the redshift user is treated as a separate user?

[@Pythoholic]

@@ITHowToAsap When a user is granted access to Amazon Redshift through IAM (Identity and Access Management), it does not automatically create a corresponding user within the Redshift cluster with the same name. IAM authentication allows you to use IAM identities (users or roles) to authenticate into your Amazon Redshift cluster, but the Redshift user management is separate from IAM.
Here's how it works:
IAM Authentication: With IAM authentication enabled for Amazon Redshift, you can use IAM identities (IAM users or IAM roles) to sign in to the Redshift cluster. This means you don't need to manage separate database credentials (username and password) within the Redshift cluster. IAM authentication provides an additional layer of security and centralizes authentication management through AWS IAM.
Redshift User Management: While IAM authentication handles the authentication part, you still need to manage user privileges and access within the Redshift cluster itself. This involves creating users and assigning roles and permissions within the Redshift database. These Redshift users and roles are separate from IAM identities and are managed within the Redshift cluster.
In practical terms, here's how it works when you use IAM authentication with Amazon Redshift:
You create an IAM user or role in your AWS account.
You grant the necessary permissions to the IAM user or role using IAM policies.
You associate the IAM user or role with the Redshift cluster's IAM authentication configuration.
When a user authenticates using their IAM credentials, they are granted access to the Redshift cluster.
Inside the Redshift cluster, you still need to create users and assign roles and permissions within the Redshift database to control what data and operations the authenticated user can access.
