IAM itself is free to use, but costs can arise from related AWS services like AWS Organizations and SSO. Properly configuring IAM Center requires setting up AWS Organizations correctly and ensuring that your IAM users and roles have the appropriate permissions. For a single AWS account, basic IAM features like users, groups, and policies are sufficient for managing access and permissions. IAM Center and other advanced features like AWS Organizations and SSO are more beneficial when managing multiple AWS accounts, especially in larger organizations where centralized access management and compliance monitoring are critical. If your use case is simple and doesn't involve managing multiple accounts or requiring advanced access controls, sticking with basic IAM features might be the most straightforward and cost-effective approach. I hope this information is helpful. If it is, please consider accepting the answer so that others can benefit from the clarity when searching for similar questions in the community. Thank you!
