Resource Group

Resource Group:  It can also be referred to as resource group ID. 

It allows ARM (Azure Resource Manager – we will discuss this in my coming post) to perform operations on a group of resources that share this ID.

A resource group is a container that holds related resources for an Azure solution. The resource group can include all the resources for the solution, or only those resources that you want to manage as a group. It stores metadata about the resources. Therefore, when you specify a location for the resource group, you are specifying where that metadata is stored

A resource group cannot include resources from different subscriptions. This is because there is a one-to-many relationship between tenant ID and subscription ID.

Multiple subscriptions can trust the same tenant to provide authentication and authorization, but each subscription can trust only one tenant. 

There is also a one-to-many relationship between subscription ID and resource group ID.

Multiple resource groups can belong to the same subscription, but each resource group can belong to only one subscription.

See all the resource groups in your subscription, select Resource groups.

In my upcoming posts, we will have a look at ARM - Azure Resource manager.
