I am researching if the Azure platform is suited for my web app.

I successfully created the Web App. The Web App in question is a Service App consisting of an WebAPI, Web Site and a DB.

As for the price tier, I chosen basic, because the throughput of the API itself is minimal. Does't take a lot of space and doesn't require high performance.

But... I do need to store some images.

Since they can get quite big, (native BMP for analyzes), I would like to add additional storage to this app without the requirements to upgrade the throughput and performance.

So, I configured a 1TB disk, but I can't see a way to give the WebApp access to this disk.

When I try to give access in IAM of the disk, I choose the option Azure AD user, group, or application. But it doens't find my web application.

I must say, the resource group is not the same. Is this important?

In general, is this a valid way to add pure storage to a web app?

Or, if not, can you advise me on how to accomplish this?


There are ways to use either .Net, Java, C++, Python to connect storage with your Web App.

A sample from the documentation on using JAVA:

it is possible to write simple applications that access the Azure File share using the standard Java I/O classes. This article will describe how to write applications that use the Azure Storage Java SDK, which uses the Azure Files REST API to talk to Azure Files.

The full documentation can be found here: https://docs.microsoft.com/en-us/azure/storage/files/storage-java-how-to-use-file-storage

On the side of the link, you will find the other languages that are supported.


Can I add extra disk storage for a Azure Web App?

The answer is no. Currently, Azure Web App does not support mount a data disk(VHD).

As Adam Smith said, you have many choices. You could store your files in Azure storage account and storage account API to use them.

  • The thing is, after some research, I was able to give the app rights on the disk (at IAM level). I am not sure if I can map it from the application. I check this later this week and get back to you on this. – Stefan Jan 29 '18 at 13:42
  • Based on my knowledge, Azure web app does not support mount vhd(blob) or a file share. – Shui shengbao Jan 30 '18 at 5:56
