Az-104 Create Custom RBAC Roles

What is RBAC?

Azure role-based access control (Azure RBAC) is a system that provides fine-grained access management of Azure resources. Using Azure RBAC, you can segregate duties within your team and grant only the amount of access to users that they need to perform their jobs.

Azure includes several built-in roles that you can use. The following are the four fundamental built-in roles. The first three apply to all resource types.

  • Owner — Has full access to all resources including the right to delegate access to others.
  • Contributor — Can create and manage all types of Azure resources but can’t grant access to others.
  • Reader — Can view existing Azure resources.
  • User Access Administrator — Lets you manage user access to Azure resources.
