The Azure Resource Manager - (ARM)

 The Azure Resource Manager - (ARM)

Prior to ARM, developers and IT professionals used the Azure Service Management API’s and the old portal (manage.windowsazure.com) to provision resources. ARM  was first announced at Build 2014 when the new Azure portal (portal.azure.com) was announced and provides a new set of API’s that are used to provision resources.

Note it:

Azure Service Management (ASM) - (manage.windowsazure.com)

Azure Resource Manager (ARM) - (portal.azure.com)

Before getting ahead with ARM, it is essential that we have an understanding of what a resource and a resource group is in Azure.

Resources, Resource Providers and Resource Groups

A resource is something you provision in your Azure subscription and always belongs to a resource group. For example, a SQL Database, Web App, Storage Account, Redis Cache, Virtual Machine, IoT Hub, and HDInsight are all examples of a resource.

Logical grouping of resources that support a particular application or workload are known as Resource Group.

Example1: IaaS workload that is consist a pair of virtual machines contained in a virtual network with a MySQL database for data.

Example2: A line-of-business (LOB) application that is comprised of a Web App, Storage Account, and a SQL Database.

 

 

 

The resources we include in a resource group generally should be those that have the same management lifecycle. If required can segregate the resource group accordingly to our requirement.

 

Each resource has a resource provider that knows how to manage and configure the resource. RP is used to create and manage the resource in the resource groups.

 

Now getting ARM, the ARM API’s, Resource Providers, Resource Groups, and Resources under a single frame.

·         Resource Groups and Resources exist in our Azure Subscription.

·         ARM and the Resource Providers are used to provision resources.

·         API’s of an ARM can be invoked once we authenticate to Azure.

 

This was a quick view of ARM and aligned components.
