Agenda 1)Azure Storage and Azure Files 2)Using Azure Files 3)Comparing to Azure Blobs 4)Comparing to Azure Disks 5)Scenarios & Demos

Azure Storage Abstractions: Blobs, Tables, Queues and now Files

PowerShell Creating a share $c = New-AzureStorageContext New-AzureStorageShare -Context $ctx 10

AzCopy Recursive copy AzCopy G:\Backups\ /DestKey:key /s 11

SMB Creating a mapped drive net use Z: \\acc.file.core.windows.net\share /u:acc key== Persisting credentials cmdkey /add:acc.file.core.windows.net /user:acc /pass:key 12

SMB In Code (P/Invoke) WNetAddConnection2 (Mpr.dll) In Code (Using RedDog.Storage) CloudFileShare share = client.GetShareReference("reports"); share.Mount("P:"); 13

SMB Credentials: persisted per user Mapped drives: persisted per user context User can have 1 normal context User can have 1 elevated context (administrator) Use /runas to store credentials and map drives for other users 14

REST Using the Storage Client Library var fileClient = storageAccount.CreateCloudFileClient(); var share = fileClient.GetShareReference("reports"); if (share.Exists()) { var dir = share.GetRootDirectoryReference(); var file = dir.GetFileReference("report.txt") var content = await file.DownloadTextAsync(); } 15
