IAM Groups

• An IAM Group is a collection of users.
• Group specifies the permission for a collection of users, and it also makes it possible to manage the permissions easily for those users.
• You created a group known as Admin and assigned the permissions to the group that administrators typically need. Any user joins the admin group; then the user will have all the permissions that are assigned to the group. If a new user joins the organization, then he should have administrator privileges, and you can assign the appropriate permissions by adding him to the group. If a person changes his job profile, instead of editing his permissions, you can remove him from a group and add him to the group.
