Blob Storage Data Model

The Blob Storage Data Model is a simple model consisting of four different components: a storage account, containers, blobs, and blocks or pages. A container is a way to organize blobs. Think of a container as a "folder" that can hold many "files". These "files" are blobs. A blob consists of one or more blocks or pages of data. In the following diagram, we can see a visual representation of a container, blobs, and blocks. Our storage account can hold an unlimited number of containers, and each container can hold an unlimited number of blobs. Each blob, as mentioned above, can be either 200 GB or smaller (block blob) or up to 1 TB (page blob). Each block in a block blob can be up to 4 MB in size, which implies that a 200 GB block blob will contain a tremendous number of blocks.
