- What is the difference between IAM users, groups, roles and policies in AWS?
A user is an identity for one person or app with long-term credentials. A group is a set of users that share permissions. A role is an identity that anyone or anything trusted can assume to get temporary credentials. A policy is the JSON document that says what is allowed or denied. Grant only the permissions needed, which is least privilege.
