KEY TERMS FOR IAM

1. User
   End-users such as employees of an organization to access the AWS resources.

2. Groups
   A collection of users is known as groups. Each user in the group will inherit the permission of the group.

3. Policies
   Policies are made up of documents called policy documents. These documents are in a format called JSON and they give permissions as to what a User / Group / Role is able to do.

4. Roles 
   The role is defined as a set of policies/permission, we can create a role and then assign them to AWS Resources.
