  2. Components of Blob Architecture
  3. Type of Blobs
  4. Container Access Levels

 

Azure Blob Storage is Microsoft's object storage solution for the cloud. Blob Storage is optimized for storing massive amounts of unstructured data. Unstructured data is data that doesn't adhere to a particular data model or definition, such as text or binary data. Its object based and easily accessible from HTTP/REST

Blob Architecture
  • Blob Service: A sub service for storage accounts.
  • Blob Container: The container where we store our blobs.
  • Blobs: The data we store in our containers.
Types of Blobs
  • Block blobs: Storing images or videos best suited for streaming.
  • Append blobs: Log files
  • Page Blobs: Virtual machine disks
Container Access Level
  • Access control:  By default, public access to blobs is granted at the storage account level
Container Access Levels:
  •  Private: No anonymous access.
