Upload/Download Files to Azure Blob Storage in a Different Tenant Using SharedServiceUnitStorage

(1) ShareShare
ReportReport
Posted on by 252

Hi All,

As some deprecation has been announced regarding Azure Blob Storage connectivity, specifically the removal of support for sharing storage account connection strings via public API (effective October 2024), we are exploring alternative approaches to connect and interact with blob storage across different tenants. The details of this deprecation can be found here:
Feature Deprecation - End of Support for Connection Strings.

Previously, we were able to seamlessly upload and download files from a blob storage account in a different tenant by utilizing connection strings. However, since this method is no longer recommended and support is ending, we are seeking a new approach using SharedServiceUnitStorage.

Could someone please guide us on the logic and steps necessary to achieve this?

Specific requirements:

  • We need to authenticate and connect to blob storage in a different tenant.
  • We are looking for a solution to upload and download files securely, without using connection strings.
  • We would like to leverage AAD authentication (OAuth 2.0) or any recommended approach, as per the latest standards, for secure and scalable interactions with blob storage.

Any code samples, best practices, or documentation references on how to implement this using SharedServiceUnitStorage would be highly appreciated.

Thanks in advance for your help!

    Hi Suren
     
    What's your scenario?
     
     
    So, this will be a problem if you are connecting to the F&O connected blob storage for an F&O instance on a different tenant - is that your scenario?

    Hi Anthony, 
     

    We have a scenario where we need to connect to a different tenant's Azure Blob Storage and perform file upload/download operations on its containers. Currently, this is working fine using connection strings.

    However, as per the deprecation notice in the link below, the end of support for sharing storage account connection strings via public API GetCsuStorageConnectionString has been announced, and the recommended approach is to use SharedServiceUnitStorage instead:
    End of Support for Connection Strings.

    Unfortunately, we don't have detailed information on how to implement SharedServiceUnitStorage for this scenario

    Thanks!

    I've come back to this, because I read about some storage deprecations this morning which could be related, and I think my answer could be incorrect because of this:
