Blob storage

What is Blob?

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.

How to access Blob?

Users or client applications can access objects in Blob Storage via HTTP/HTTPS, from anywhere in the world.

3 kinds of blob storage

  • Block: Variable size blocks, optimized for large blobs
  • Page: fixed size blobs, 512 bytes for example. Optimized for random read/write
  • Append: used for append operations


Blob Storage supports Azure Data Lake Storage Gen2, Microsoft's enterprise big data analytics solution for the cloud.
