Azure Blob Storage

Azure Blob Storage is Microsoft's object storage solution for the cloud. It is optimized for storing massive amounts of unstructured data.

Key Features

  • Access Tiers: Hot (frequently accessed), Cool (infrequently accessed), Cold (rarely accessed), Archive (long-term retention).
  • Redundancy: LRS (Locally Redundant), ZRS (Zone Redundant), GRS (Geo-Redundant).
  • Security: Encryption at rest, granular access control with SAS tokens or Entra ID.

Use Cases

  • Serving Images/Documents: Storing files for browser access.
  • Streaming: Video and audio streaming.
  • Backup and Restore: Storing backup data and disaster recovery files.
  • Data Lakes: Storing data for analysis by Azure Synapse or Databricks (Data Lake Gen2).

Key Concepts

  • Container: A logical grouping of blobs (like a folder).
  • Blob Types: Block Blobs (text/binary), Append Blobs (logs), Page Blobs (VHDs).
  • Lifecycle Management: Automated policies to move data between tiers or delete it.
