Data access from the Azure portal

The Azure portal can use either your Microsoft Entra account or the account access keys to access queue data in an Azure storage account. Which authorization scheme the Azure portal uses depends on the Azure roles that are assigned to you.

When you attempt to access queue data, the Azure portal first checks whether you've been assigned an Azure role with Microsoft.Storage/storageAccounts/listkeys/action. If you've been assigned a role with this action, then the Azure portal uses the account key for accessing queue data via Shared Key authorization. If you haven't been assigned a role with this action, then the Azure portal attempts to access data using your Microsoft Entra account.

To access queue data from the Azure portal using your Microsoft Entra account, you need permissions to access queue data, and you also need permissions to navigate through the storage account resources in the Azure portal. The built-in roles provided by Azure Storage grant access to queue resources, but they don't grant permissions to storage account resources. For this reason, access to the portal also requires the assignment of an Azure Resource Manager role such as the Reader role, scoped to the level of the storage account or higher. The Reader role grants the most restricted permissions, but another Azure Resource Manager role that grants access to storage account management resources is also acceptable.

Azure built-in roles for tables

Azure RBAC provides built-in roles for authorizing access to table data using Microsoft Entra ID and OAuth. Built-in roles that provide permissions to tables in Azure Storage include: Storage Table Data Contributor: Use to grant read/write/delete permissions to Table storage resources. Storage Table Data Reader: Use to grant read-only permissions to Table storage resources. To learn how to assign an Azure built-in role to a security principal, see Assign an Azure role for access to table data. To learn how to list Azure RBAC roles and their permissions, see List Azure role definitions. For more information about how built-in roles are defined for Azure Storage, see Understand role definitions. For information about creating Azure custom roles, see Azure custom roles. Only roles explicitly defined for data access permit a security principal to access table data. Built-in roles such as Owner, Contributor, and Storage Account Contributor permit a security principal to manage a storage acc...

Explore Dataflows Gen2 in Microsoft Fabric

  In Microsoft Fabric, you can create a Dataflow Gen2 in the Data Factory workload or Power BI workspace, or directly in the lakehouse. Since our scenario is focused on data ingestion, let's look at the  Data Factory  workload experience. Dataflows Gen2 use Power Query Online to visualize transformations.  1. Power Query ribbon Dataflows Gen2 support a wide variety of data source connectors. Common sources include cloud and on-premises relational databases, Excel or flat files, SharePoint, SalesForce, Spark, and Fabric lakehouses. Then there are numerous data transformations possible, such as: Filter and Sort rows Pivot and Unpivot Merge and Append queries Split and Conditional split Replace values and Remove duplicates Add, Rename, Reorder, or Delete columns Rank and Percentage calculator Choose Top N and Bottom N You can also create and manage data source connections, manage parameters, and configure the default data destination in this ribbon. 2. Queries pane The ...

Select and configure an appropriate method for access to Azure Blobs

Azure Storage supports using Microsoft Entra ID to authorize requests to blob data. With Microsoft Entra ID, you can use Azure role-based access control (Azure RBAC) to grant permissions to a security principal, which may be a user, group, or application service principal. The security principal is authenticated by Microsoft Entra ID to return an OAuth 2.0 token. The token can then be used to authorize a request against the Blob service. Authorization with Microsoft Entra ID is available for all general-purpose and Blob storage accounts in all public regions and national clouds. Only storage accounts created with the Azure Resource Manager deployment model support Microsoft Entra authorization. For optimal security, Microsoft recommends using Microsoft Entra ID with managed identities to authorize requests against blob, queue, and table data, whenever possible. Authorization with Microsoft Entra ID and managed identities provides superior security and ease of use over Shared Key author...
