Microsoft Azure Blob Storage enables the secure, highly available storage of large unstructured binary data (BLOB = binary large object) in Microsoft Azure. A single blob can have a size of up to 1 terabyte. Content is automatically stored in triplicate.

Other available options are georeplication and the ability to cache blob content distributed worldwide via the content delivery network (see 6.2). Two types of blobs are available: block blobs and page blobs. The former are suitable for sequential data upload and download, while the latter provide random access to Blob sections.

Blobs are stored within containers. Access privileges can be assigned both at the container level and the Blob level. The relevant element can be declared as public (access possible without authentication) or private. Shared Access Signatures can be created to time-limit access to appropriately authorized users.
