Azure portal (ARM model)

In 2014, Microsoft launched a new portal which follows a new model, called the ARM model. This portal can be accessed via the following URL https://portal.azure.com/.

This model depends on the concept of resource groups, which means you can group all your resources within a container, resulting in resources being deployed in parallel. As a result, you will not face the same problems as you did with the classic portal.

The following diagram describes the deployed resources through the ARM model:

Here are the benefits you will gain using this portal:

Ability to manage your resources as a group instead of managing them separately.
Use Role Based Access Control (RBAC) to control access to resources, so that you can assign permissions to a user on a resource or some resources but not to other resources (as it was in the classic portal).
Use tags to organize and classify your resources, which can help you with billing. For example, you might want to monitor the billing of some resources that make up a solution, for example, a web server. By assigning a tag to the resources that make up that solution, you would be able to monitor its billing, and so on.
Support the usability of JSON to deploy resources instead of using the portal.
- Deploy resources in parallel instead of deploying them sequentially and waiting until every resource deployment finishes to deploy another one.
- Specify dependencies during the deployment of resources. For example, a VM will not be created until a storage account and a virtual network are deployed because the VM VHD would need a place to be stored in and an IP Address from a virtual network./li>
- Reuse the JSON template to deploy a solution with the same specifications.

Resources with the same life cycle should be gathered in the same resource group.
Resources in different regions can be in the same resource group.
The resource cannot exist in multiple resource groups.
A resource group supports RBAC, wherein a user can have access to some specific resources, but no access to others.
Some resources can be shared across resource groups, such as storage accounts.
ARM VMs can only be placed in ARM storage accounts.

When you open the Azure portal, it will look like the following screenshot:

You can change the background of the portal by double-clicking on any unused area of the dashboard. You can navigate between four colors (blue, dark blue, white, and black).
