IAM Group

Collection of IAM users that share attached permission policies.

Definition

IAM groups simplify permission management by attaching policies to the group rather than each user. Groups cannot be nested, cannot be principals in resource-based policies and cannot assume roles themselves.

Example

All developers are added to a Developers group that has a policy allowing access to development resources.

Exam tip

Groups contain users only, not other groups or roles; a group is not a principal you can reference in a bucket policy.
