Azure Storage Blobs Overview

What are Azure Storage Blobs?

Azure Blob Storage is Microsoft's object storage solution for the cloud. It's optimized for storing massive amounts of unstructured data, such as text or binary data, like images, documents, streaming media, application data, and backups.

Blobs can be any type of text or binary data. Blob storage is commonly used for:

Serving images or documents directly to a browser.
Storing files for distributed access.
Streaming video and audio.
Writing to log files.
Storing data for backup and restore, disaster recovery, and archiving.
Storing data for analysis by an on-premises or Azure-hosted service.

Key Concepts

Storage Accounts

A storage account provides a unique namespace in Azure for your data object. All objects in a storage account are accessible via HTTP or HTTPS. A storage account includes:

Blob Storage: For storing unstructured data.
File Storage: For shared Windows file shares.
Queue Storage: For reliable messaging between application components.
Table Storage: For NoSQL key-attribute storage.

Blob Types

Azure Storage supports three types of blobs:

Block Blobs: Optimized for storing large amounts of unstructured data, such as documents or media files. Block blobs are composed of blocks of data.
Append Blobs: Optimized for append operations, such as logging data. Data can only be added to the end of an append blob.
Page Blobs: Optimized for random read and write operations. Page blobs are used for IaaS virtual machine disks and SQL Server data files.

Getting Started

To start using Azure Blob Storage, you'll need an Azure subscription. You can then create a storage account and begin uploading blobs.

Example: Uploading a file using Azure CLI

az storage blob upload \
    --account-name  \
    --container-name  \
    --name my-blob.txt \
    --file my-local-file.txt \
    --auth-mode login

You can also use SDKs for various programming languages (Python, .NET, Java, Node.js) or the Azure portal for managing your blobs.
