Windows Azure Drive
The document discusses Windows Azure Drive, which allows mounting cloud storage as a virtual disk. It provides examples of uploading files to Azure blob storage using page blobs. There are different modes for accessing the drive, including lease mode and snapshot mode. The workflow involves mounting the drive, handling exceptions by remounting from a snapshot, and unmounting. The document compares storage emulators to Azure storage services and provides a reference to learn more about Windows Azure Drive.
