Azure Resource Manager (ARM)

Azure's deployment and management service; every request from portal, CLI, PowerShell or SDK passes through it.

Definition

ARM authenticates and authorizes requests, applies RBAC, Azure Policy and locks, and sends them to resource providers. It enables declarative deployments with ARM templates and Bicep, consistent tagging and resource grouping.

Example

Creating a VM from the portal and from az vm create both result in ARM API calls to the Microsoft.Compute provider.

Exam tip

Because all tools go through ARM, RBAC and policies apply consistently no matter how a resource is created.
