  • This is an object that represents a user, a group, service pricipal or managed identity that is request to Azure Resources
• Role Definition
  • This is a collection of permissions typically called as role.
  • This list actions that can be performed such as read, write and delete
  • Azure has several built in roles Refer Here
• Scope:
  • This is set of resources that the access applies to
    
• Role Assignment
  • This is the process of attaching a role definition to a user/group/service prinicipal/managed identity at a particular scope for the purpose of granting access.
