What is AWS IAM?

AWS IAM (Identity and Access Management) enables you to securely control access to AWS services and resources. It allows you to create and manage AWS users, groups, and roles, and define permissions using policies to allow or deny access to AWS resources. IAM supports multi-factor authentication (MFA) for enhanced security and provides fine-grained access control through policy conditions. You can grant temporary access using IAM roles and integrate with corporate identity systems using federation. IAM is a global service available across all AWS regions and is offered at no additional charge.
