Azure Storage Account

Updated: May 10

Azure Storage is the cloud storage solution for modern applications that rely on durability, availability, and scalability to meet the needs of their customers.

The first thing we need to use in Azure is a storage account.

Azure Storage Account

Azure Storage Accounts

To use any storage type in Azure, we first have to create an account there. After creating an account, we can transfer data to or from services in our storage account. Create a storage account to store up to 500 TB of data in the cloud. Use the Blob storage account and the hot or cool access tiers to optimize your costs based on how frequently our object data is accessed.

A storage account can be of two types:

  1. General Purpose

  2. Blob Storage

General Purpose Storage Account

A general-purpose storage account provides a space that gives us access to blobs, queues, files and tables, all of these services in a unified account. A general-purpose storage account can be used to store object data, as a NoSQL data store, define and use queues for message processing, and set up file shares in the cloud.

Azure storage accounts 4 types of storage types in Azure:

  • Tables

  • Blobs

  • Queues

  • File Storage


The Azure Table storage service stores large amounts of structured data. The service is a NoSQL datastore which accepts authenticated calls from inside and outside the Azure cloud. Azure tables are ideal for storing structured, non-relational data.


Azure Blob storage is a service that stores unstructured data in the cloud as objects/blobs. Blob storage can store any type of text or binary data, such as a document, media file, or application installer. Blob storage is also referred to as object storage.


Azure Queue storage is a service that stores large numbers of messages that can be accessed from anywhere in the world via authenticated calls using HTTP or HTTPS. A single queue message can be up to 64 KB, and a queue can contain millions of messages up to the total capacity limit of a storage account.

File Storage

A File Storage share is an SMB file share in Azure. All directories and files must be created in a parent share. An account can contain an unlimited number of shares, and a share can store an unlimited number of files, up to the 5 TB total capacity of the file share.

Blob Storage

Blob storage accounts are specialized in storing blob data and can also be used to choose an access tier, which allows you to specify how frequently data in the account is accessed. You can select an access tier suitable for your storage and which suits your expenses.

There are three types of access tiers –


Ideal for frequently accessed data. Although it comes with higher storage costs, its lower access fees make it perfect for active data you need to retrieve often.


Great for data that sits idle most of the time but is expected to be accessed infrequently. It’s more budget-friendly for storing data like old project files or infrequent backups.


The cost-effective choice for data you rarely touch, such as regulatory records or historical information. It offers the lowest storage price at the expense of higher retrieval costs.

Azure Storage Replication

We have four options in the ‘Replication’ dropdown for Azure standard storage accounts. A copy of the data is kept so that it is durable and available at high speed. It is retained even in case of hardware failure.

Locally redundant storage

A copy of the data is created in the same region where the storage account is created. There are 3 copies of each request made against the data that resides on separate domains.

Zone-redundant storage (available for blobs only)

A copy of the data is created on separate facilities either in the same region or across two regions. The advantage is that even if there is a failure in one facility, the data can still be retained. Three copies of data are created. One more advantage is that data can be read from a secondary location.

Geo-redundant storage

Copy is created in a different region, which means data is retained even if there is a failure in the entire area. The number of copies of data produced is 6 in this case.

Read-access geo-redundant storage

This option allows data to be read from a secondary location when data from the primary location is unavailable. The number of copies created is 6. The main advantage here is that the availability of data can be maximized.
