Azure storage types

Storage Types
Each storage account can contain the following types of storage. You can use more than one of these types in the same storage account:BLOB Storage

  • Binary Large Objects (BLOBs) can be any type of file or binary data.
  • This can include documents, images, videos, backup files, configuration files, and data logs.
  • You can create any number of containers within a single storage account.
  • Within each container, you can store any number of blobs up to the 500 TB limit.
  • BLOB has two sub types as
    • Page BLOB:
      • Page blobs are designed for random read and write operations.
      • Blobs are accessed as pages, each of which is up to 512 bytes in size.
      • When you create a page blob, you specify the maximum size to which it may grow up to a limit of 1 TB.
    • Block BLOB:
      • Block blobs are designed to enable developers to upload large files efficiently.
      • Data is uploaded in the form of data blocks, each of which is up to 4 MB in size.
      • Block blobs can be up to 200 GB in size.

Table Storage

  • You can use tables to store data without specifying a schema as you would in a database.
  • This schema-less design makes it easy for developers to adapt a table to changing requirements.
  • Developers can use table storage as the back-end data store for websites, mobile apps, PaaS cloud services, and other types of solution.

Queue Storage

  • When developers architect distributed applications, they need a method by which components of the application can reliably communicate asynchronously.
  • One popular method is to use a queue: a source component sends a message by placing it into a queue.
  • The destination component works though the messages in the queue one at a time.
  • You can use Azure Queue Storage to provide such a message queue with all the redundancy and reliability provided by Azure Storage.

File Storage

  • Azure file storage enables you to create an SMB file share.
  • Client computers can browse this share or map a network drive to the share as they might access a file share on an on-premises Windows file and print server.
