Azure Resource Manager Replaces Classic Model

Azure Resource Manager is a software framework that drives the deployment and management of Azure resources, such as virtual machines (VMs), Web apps, and databases. Resource Manager helps customers organize, govern, and secure resources deployed on Azure, and it is due to replace the previous “classic” Azure deployment framework, which may no longer be supported by mid-2017. Customers relying on the classic model may need to perform procedures to migrate to Resource Manager, and new deployments should use Resource Manager in most cases.

Resource Manager Overview

Resource Manager is an extensible framework with APIs that enable organizations to structure sets of Azure resources for repeatable deployment and updating, secure and govern resource management, tag resources for internal billing and navigation, and log resource activity for auditing and diagnosis.

Extensible Framework with REST APIs

The Resource Manager framework uses pluggable resource providers, which enable deployment, updating, and other management operations on Azure resources. Microsoft offers providers for standard Azure resources, such as VMs and databases, and third parties can create providers for custom resources.
