Exercise - Create an Azure Storage account for Azure Data Lake Storage
Before you can upload or transfer data into a data lake, you need to create one. Using the Azure portal, you can provision an Azure Data Lake Storage Gen2 store within minutes.
Note
If you don't have an Azure account or prefer not to do this exercise in your account, just read through the exercise to understand how to create a Data Lake Storage Gen2 store.
Create a resource group
Create a new resource group to hold the data lake storage. You use the resource group to administer related services and applications together. A resource group also makes resource clean up easier when you finish this module.
To create a resource group in the Azure portal, follow these steps:
Sign in to the Azure portal.
On the Home page, under Azure services, select Create a resource.
In the search box, enter Resource group and press Enter. The Resource group pane appears.
Select Create to add a new resource group.
On the Basics tab, enter the following values for each setting.
Setting Value Project details Subscription Subscription you choose to work in. Resource group Enter mslearn-datalake-test Resource details Region Select a location for the resource group. Typically, you want a location that's close to you or to the data you work with. 
Select Review + create.
After validation passes, select Create.
After the resource group is created, select Go to resource group. Optionally, from the Notifications icon in the portal menu (title bar), select Pin to dashboard to make it easy to find later.
Create a Data Lake Storage Gen2 account
You create a Data Lake Storage Gen2 account the same way you create an Azure Blob store, but with one different setting.
On the Resource Group page, select Create resources. The Create a resource page appears.
In the resource menu, select Storage, and then search for Storage account, and press Enter. The Storage account pane appears.
Select Create. The Create a storage account pane appears.
On the Basics tab, enter the following values for each setting.
Setting Value Project details Subscription Same subscription as the Data Lake Storage Gen2 account you created. Resource group From the dropdown list, select mslearn-datalake-test Instance details Storage account name Enter a unique name for your storage account. The name must be unique across all of Azure. You might have to try a few variations to find a unique name. Try using the prefix dlakedata with some numbers. A green check mark indicates you've entered a valid name. Region From the dropdown list, select (US) Central US. Accept the defaults for the remainder of the settings.
Select Next : Advanced.
