Feature Request - Azure Support for DMS Installer

[andricDu]

As Score supports using Azure as the backing object store, the DMS installer should be able to provide the option for running against an Azure storage account.

Detailed Description

• Even though Song/Score can run in Azure and utilize the capabilities of blob storage in Azure, the DMS installer does not provide a way for end users configuring their installation to point it to an azure storage account.
• This would be useful as it would allow users who are already using Azure to use the DMS
• @prbatero from Microsoft suggested they could even point users looking for DMS-like solutions to Overture.bio

Possible Implementation

• Implement a question in installer asking if users would like S3 or Azure Storage for Score
  • In the case of azure storage, they will need to provide storage account, an account secret, and the access policies for reads and writes to be assigned the Shared Access Signatures (Azure equivalent to S3 Presigned URL)
• Update documentation to reflect these new options and what they refer to

Thanks @andricDu. Regarding the params you mentioned above, would the DMS installer need to use the Create Container operation in the Azure Blob Service REST API?

The request headers accept an account name, a signature (which seems is the storage account key/secret), and level of access. But I'm not sure if it's the exact endpoint you were referring to:
