As a totally managed service, it gives excessive efficiency and scalability whereas permitting safe entry to the information saved within the information warehouse. Organizations worldwide depend on Amazon Redshift to deal with large datasets, improve their analytics capabilities, and ship invaluable enterprise intelligence to their stakeholders.

AWS IAM Identification Middle serves as the popular platform for controlling workforce entry to AWS instruments, together with Amazon Q Developer. It permits for a single connection to your present id supplier (IdP), making a unified view of customers throughout AWS functions and making use of trusted id propagation for a easy and constant expertise.

You’ll be able to entry information in Amazon Redshift utilizing native customers or exterior customers. An area person in Amazon Redshift is a database person account that’s created and managed straight throughout the Redshift cluster itself. Amazon Redshift additionally integrates with IAM Identification Middle, and helps trusted id propagation, so you should use third-party IdPs similar to Microsoft Entra ID (Azure AD), Okta, Ping, OneLogin, or use IAM Identification Middle as an id supply. The IAM Identification Middle integration with Amazon Redshift helps centralized authentication and SSO capabilities, simplifying entry administration throughout multi-account environments. As organizations develop in scale, it is suggested to make use of exterior customers for cross-service integration and centralized entry administration.

On this submit, we stroll you thru the method of easily migrating your native Redshift person administration to IAM Identification Middle customers and teams utilizing the RedshiftIDCMigration utility.

Answer overview

The next diagram illustrates the answer structure.

The RedshiftIDCMigration utility accelerates the migration of your native Redshift customers, teams, and roles to your IAM Identification Middle occasion by performing the next actions:

• Create customers in IAM Identification Middle for each native person in a given Redshift occasion.
• Create teams in IAM Identification Middle for each group or function in a given Redshift occasion.
• Assign customers to teams in IAM Identification Middle in line with present assignments within the Redshift occasion.
• Create IAM Identification Middle roles within the Redshift occasion matching the teams created in IAM Identification Middle.
• Grant permissions to IAM Identification Middle roles within the Redshift occasion primarily based on the present permissions given to native teams and roles.

Conditions

Earlier than working the utility, full the next stipulations:

1. Allow IAM Identification Middle in your account.
2. Observe the steps within the submit Combine Identification Supplier (IdP) with Amazon Redshift Question Editor V2 and SQL Shopper utilizing AWS IAM Identification Middle for seamless Single Signal-On (particularly, observe Steps 1–8, skipping Steps 4 and 6).
3. Configure the IAM Identification Middle utility assignments:
   1. On the IAM Identification Middle console, select Utility Assignments and Functions.

Deploy the answer

Full the next steps to deploy the answer:

1. Replace Redshift cluster or serverless endpoint particulars and Amazon S3 location in redshift_unload.ini:
   • cluster_type = provisioned or serverless
   • cluster_id = ${cluster_identifier} (required if cluster_type is provisioned)
   • db_user = ${database_user}
   • db_name = ${database_name}
   • host = ${host_url} (required if cluster_type is provisioned)
   • port = ${port_number}
   • workgroup_name = ${workgroup_name} (required if cluster_type is serverless)
   • area = ${area}
   • s3_bucket = ${S3_bucket_name}
   • roles = roles.csv
   • customers = customers.csv
   • role_memberships = role_memberships.csv
2. Replace IAM Identification Middle particulars in idc_config.ini:
   • area = ${area}
   • account_id = ${account_id}
   • identity_store_id = ${identity_store_id} (out there on the IAM Identification Middle console Settings web page)
   • instance_arn = ${iam_identity_center_instance_arn} (out there on the IAM Identification Middle console Settings web page)
   • permission_set_arn = ${permission_set_arn}
   • assign_permission_set = True or False (True if permission_set_arn is outlined)
   • s3_bucket = ${S3_bucket_name}
   • users_file = customers.csv
   • roles_file = roles.csv
   • role_memberships_file = role_memberships.csv
3. Create a listing in CloudShell or by yourself EC2 occasion with connectivity to Amazon Redshift.
4. Copy the 2 .ini information and obtain the Python scripts to that listing.
5. Run idc_redshift_unload_indatabase_groups_roles_users.py both from CloudShell or your EC2 occasion:python idc_redshift_unload_indatabase_groups_roles_users.py
6. Run idc_add_users_groups_roles_psets.py both from CloudShell or your EC2 occasion:python idc_add_users_groups_roles_psets.py
7. Join your Redshift cluster utilizing the Amazon Redshift question editor v2 or most popular SQL consumer, utilizing superuser credentials.
8. Copy the SQL within the vw_local_ugr_to_idc_urgr_priv.sql file and run it within the question editor to create the vw_local_ugr_to_idc_urgr_priv view.
9. Run following SQL command to generate the SQL statements for creating roles and permissions:

   choose existing_grants,idc_based_grants from vw_local_ugr_to_idc_urgr_priv;

   For instance, think about the next present grants:

   CREATE GROUP "group_adhoc";
   CREATE ROLE "role_bn_etl_tickit";
   GRANT USAGE ON SCHEMA tpcds TO function "role_tn_sel_tpcds" ;

   These grants are transformed to the next code:

   CREATE function "AWSIDC:group_adhoc";
   CREATE function "AWSIDC:role_bn_etl_tickit";
   GRANT USAGE ON SCHEMA tpcds TO function "AWSIDC:role_tn_sel_tpcds";

10. Assessment the statements within the idc_based_grants column.
    This may not be a complete checklist of permissions, so evaluation them fastidiously.
11. If the whole lot is right, run the statements from the SQL consumer.

When you may have accomplished the method, you need to have the next configuration:

• IAM Identification Middle now incorporates newly created customers from Amazon Redshift
• The Redshift native teams and roles are created as teams in IAM Identification Middle
• New roles are established in Amazon Redshift, comparable to the teams created in IAM Identification Middle
• The newly created Redshift roles are assigned acceptable permissions

In the event you encounter a problem whereas connecting to Amazon Redshift with the question editor utilizing IAM Identification Middle, seek advice from Troubleshooting connections from Amazon Redshift question editor v2.

Concerns

Contemplate the next when utilizing this resolution:

• On the time of writing, creating permissions in AWS Lake Formation is just not in scope.
• IAM Identification Middle and IdP integration setup is out of scope for this utility. Nevertheless, you should use the view vw_local_ugr_to_idc_urgr_priv.sqlto create roles and grant permissions to the IdP customers and teams handed via IAM Identification Middle.
• If in case you have permissions given on to native person IDs (not utilizing teams or roles), you could change that to a role-based permission method for IAM Identification Middle integration. Create roles and supply permissions utilizing roles as a substitute of straight giving permissions to customers.

Clear up

If in case you have accomplished the testing state of affairs, clear up your atmosphere:

1. Take away the brand new Redshift roles that had been created by the utility, comparable to the teams established in IAM Identification Middle.
2. Delete the customers and teams created by the utility inside IAM Identification Middle.
3. Delete the customers, teams, and roles specified within the testing state of affairs.
4. Drop the tickit and tpcds schemas.

You should utilize the FORCE parameter when dropping the roles to take away related assignments.

Conclusion

On this submit, we confirmed methods to migrate your Redshift native person administration to IAM Identification Middle. This transition gives a number of key benefits to your group, similar to simplified entry administration via centralized person and group administration, a streamlined person expertise throughout AWS providers, and diminished administrative overhead.
