What is a resource group?
A resource group is a fundamental concept in cloud computing, commonly used by major cloud service providers like Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP). Essentially, a resource group is a logical container that holds related resources for a specific application or project.

How to create a resource group
Open your web browser and enter Azure Portal. To access the portal sign in with your Azure account credentials. Once you've entered into the Azure Portal, in the search tab, search and select "Resource groups" Once on the "Resource groups" page, click on the "Create" button. Select the Azure subscription you want to use for the resource group, for me it was "Azure subscription 1". Put in a name for your resource group. Select the region where you want the data for your reference group stored.

It's best to choose a region where your resources will be deployed. After all the necessary details have been entered, click the "Review + create" button. Once the validation passes, click on the "Create" button. After the resource group is created, you can access it by going to "Resource groups" in the Azure Portal.
