This article will explain in detail how to understand Blob storage. The content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have some understanding of the relevant knowledge after reading this article.

Block Blob storage is used to stream and store documents, videos, pictures, backups, and other unstructured text or binary data.

The total cost of Block Blob storage depends on:

The amount of data stored each month.

The number and type of operations performed, as well as any data transfer costs.

Data redundancy option is selected

In short:

Block Blob: for large objects that do not use random read and write operations. For example, pictures

Page Blob: optimized for random read and write operations. For example, VHD

Additional Blob: optimized for append operations. For example, log

Block Blob

These blob are ideal for storing documents and text or binary media files. 50000 blocks of up to 100 MB each can be stored in a single block blob with a total block size of more than 4750 GB or 4.75 TB. (50000 * 100MB).

Additional blob

Additional blob is similar to Block blob, but is more suitable for additional operations, which makes the appended blob more suitable for storing logging scenarios. The difference between additional blob and block blob is storage capacity. This blob can only store data from 4MB at most, unlike 100MB in block blob. Therefore, the additional block is limited to a storage capacity of more than 195 GB. (50000 * 4 MB).

Page Blob

Page blobs can store about 8 TB of data, which makes it very efficient and suitable for scenarios that require high read and write operations. This Blob storage option is useful for all Azure virtual machine storage disks, including operating system disks. In Azure, there are two-page blob categories, such as Standard, for virtual machines with average read / write operations, and Premium for intensive read / write operations on virtual machines.

Three types of blob are supported for Azure storage:

Description

Block blob

Block blob is used to save text or binaries with a size of about 5 TB (50000 blocks, 100 MB). The main use case for block blob is to store files that are read from beginning to end, such as media files or image files for Web sites. They are named block blob because files larger than 100 MB must be uploaded as small chunks and then merged (or submitted) into the final blob.

Page blob

The page blob is used to save random access files up to 8 TB. Page blob is mainly used as backup storage for VHD to provide persistent disks for Azure virtual machines (Azure VM). They are named page blob because they provide random read / write access to 512-byte pages.

Additional blob

The additional blob consists of blocks such as blob, but they are optimized for append operations. These are typically used to record information from one or more sources to the same blob. For example, you can write all trace log records to the same appended blob of an application running on multiple VM. A single additional blob can reach up to 195 GB.
