IAM Role in AWS

In AWS IAM Roles are similar to IAM Users in that they can have policies and permissions attached to them. However, they cannot be authorized (login) and they do not really have the policies etc attached to them. They appear to have them but underneath, those policies flow down the the actual users beneath.

The idea is that Roles will help you to group users together and also that they can help you in temporarily granting a level of access or permission to a user and give you an easy way to revoke that.

What is the use of IAM Role in AWS

You might create an IAM role in AWS if you want to give all users on project x permissions on the objects that are used for that project, Then if a user moves teams, you can take that role of them and assign them another one without disrupting the rest of the team.

This allows you to add permissions for the whole team in one place and have it automatically passed to everyone that needs it.
