Blobs are ideally suited for unstructured binary and text data.One of the main benefits is that, once stored, the corresponding information can be accessed from anywhere using the HTTP or HTTPS protocols.The items in Blob storage can range up to 100 TB.
Blob storage is ideally suited for the following:
- Images that can be directly viewed in a browser
- Document storage
- Secure backups as part of a disaster recovery plan
- Streaming video and audio
Windows Azure has two distinct categories of blobs:
a)Block Blob : have a 200 gigabyte (GB) size limit
b)Page blob : can store anything up to 1 TB.
