Azure Blob Storage

• Blob Storage is ideal for
  • Serving images or documents directly to browser
  • Storing files for distributed access
  • Streaming audio & video files
  • Log Files
  • Backup, Restore, Disaster Recovery
• To use Blob Storage, we can use GPV1 GPV2 or Block Blob Storage.
• In Block Blob Storage, we have three resources
  • Storage Account
  • Container
  • Blob
• When we create an azure storage account a unique namespace in azure is created for the data. for example if we create a storage account with name qtstorageaccount, default endpoint for Blob storage will be http://qtstorageaccount.blob.core.windows.net
• So due to this storage account names have to be unique accross azure.
• Lets create a storage account
• Containers: Container organizes set of blobs (Similar to folder in filessystem)
• Each item which we upload to the Container is blob and every blob can be accessed over url
• Block blobs store text and binary data (any file). Block blobas are made up of blocls of data
• Maxium size of the file in Block storage is 4.75 TiB.
• Page blobs store disks upto 8TiB in size
