Understanding Containers and Blobs

Azure Blob Storage is built around two core concepts: containers and blobs. A container is a logical unit that holds a collection of blobs. Blobs, on the other hand, are binary large objects that store unstructured data, such as text and binary data. Containers provide a way to organize and manage blobs, making it easier to handle large amounts of data in Azure Blob Storage.

There are three types of blobs in Azure Blob Storage:

Block blobs: Ideal for storing text and binary data, block blobs are made up of blocks of data that can be managed individually. They can store up to 4.75 TiB of data and are suitable for applications that require large objects, such as multimedia files, documents, and backups.
Append blobs: Designed for append operations, append blobs are similar to block blobs but optimized for append-only writes. They can store up to 4.75 TiB of data and are commonly used for logging, auditing, and telemetry data.
Page blobs: Optimized for random writes, page blobs store data in 512-byte pages. They can store up to 8 TiB of data and are primarily used for storing virtual machine disks in Azure.

In this section of the azure blob storage tutorial, you have learned about the fundamental concepts of containers and blobs, as well as their different types. In the following sections, you will learn how to upload, download, and manage blobs using tools like Azure Storage Explorer and Azure CLI.
