Azure Role-Based Access Control (RBAC) provides fine-grained access management for Azure resources, so you can grant users only the rights they need to perform their jobs by using built-in or custom roles.
RBAC is provided at no additional cost to all Azure subscribers. You can download the RBAC command-line management tools
or use the Azure portal
to manage access for your Azure production workloads. For more information, please visit the Active Directory Team Blog
