Blob Storage

What Does Blob Storage Mean?

Blob storage is a feature in Microsoft Azure that lets developers store unstructured data in Microsoft’s cloud platform. This data can be accessed from anywhere in the world and can include audio, video and text. Blobs are grouped into “containers” that are tied to user accounts. Blobs can be manipulated with .NET code.


Techopedia Explains Blob Storage

Blob storage allows Microsoft Azure to store arbitrarily large amounts of unstructured data and serve them to users over HTTP and HTTPS.

Microsoft’s use cases include serving streaming video, files, text and images to remote users. Azure allows users to store blobs in containers. A blob might be dedicated solely to video while another might store image files.

Microsoft defines three types of blobs: block blobs, append blobs and page blobs. Block blobs support up to 50,000 blocks up to 4 megabytes, with up to 195 gigabytes in total. Block blobs are intended for text and other binary files. Append blobs support appending operations and are designed for log files. Page blobs are designed for frequent read/write operations. Blobs are created and accessed with .NET code.
