The Azure BLOB provider offloads media and file storage from the local file system to Azure Blob Storage, enabling scalable cloud-based content delivery.

Install the `EPiServer.Azure` package, which provides extension methods on the `IServiceCollection` interface.

The following example shows how to add the Azure BLOB provider to your application:

```csharp
using EPiServer.ServiceLocation;
using Microsoft.Extensions.DependencyInjection;
using System;

namespace SampleBlob {
  public class Startup {
    public void ConfigureServices(IServiceCollection services) {
      services.AddAzureBlobProvider(o => {
        o.ConnectionString = "<The Azure storage connection string>";
        o.ContainerName = "<The container name>";
      });
    }
  }
}
```
