Microsoft provides a smart solution for modern-day storage circumstances which is Azure Storage. With data growing day by day, we need to upscale our method of storage as well. Azure storage provides massive scalability with security, durability, and much more.
Before moving on, below are the topics that I will be talking about in this blog. In case you want to know about a particular point, you can skip to that part.
- What is Azure storage
- Features of Azure storage
- Azure Storage Types
- Azure Blob Storage

In case you are more intrigued by videos than reading, here is a video on Azure storage:
So, how does storing data in cloud impact any business or people in general?
- The first and foremost advantage is not needing any hardware or physical space. When you do not need any infrastructure, you save money as well.
- You can scale up or down your storage space as per your requirements.
- Availability is another factor that makes storing data in the cloud an ideal solution.
Before moving on with Azure storage, you can brush up your basics on Azure by reading this blog: What Is Microsoft Azure?
Now that we know why opting to store data in the cloud is important, let us see what is Azure Storage.
What is Azure Storage
As I said before, Azure storage is the modern day solution to all storage problems. The storage capacity is limitless, virtually. Being a pay-as-you-go model, it gives you the flexibility of paying only for what you have used. Azure Storage supports different clients like .NET, Ruby, Java, etc which gives developers an option.
To access any of the storage services, you must have an Azure storage account. To do so, first, create an Azure account. I will get back on how to get started with Azure storage in the later part of this blog.
Now that you know what is Azure Storage, let us have a look at its features.

Features of Azure Storage
Let us look at the features of Azure Storage:
- Durability and highly available: Stored data is replicated in different geographical locations. Hence, in case of any hardware failure, you have your replicas and so your data is safe. Also, if there is any natural disaster, your data will remain secure and you can avail them pretty easily.
- Scalable: The storage is massively scalable depending on the requirements. Data is automatically scaled up to accommodate any peak demands.
- Security: Accessing any information from your storage is not an easy task and hence your data is secure. Azure Storage uses a shared key model to authenticate a user. Usage of the shared access signature (SAS) can restrict access to data.
- Accessible: You can access your data from anywhere over HTTP or HTTPS. You can write your code on Azure PowerShell or Azure CLI. Azure Storage Explorer and Azure portal provide you an easy way to work with your data.

Now that you know the features of Azure Storage, let us have a look at the different Azure Storage Types in the section below.
Azure Storage Types
There are four primary Azure storage types with additional disk storage.
- Azure blob storage: optimized to store huge unstructured data. Storage is in terms of binary large objects (BLOBs).
- Azure table storage: it has now become a part of Azure Cosmo DB. Azure table stores structured NoSQL data.
- Azure file storage: it is a fully managed file sharing in cloud or on-premise via Server Message Block (SMB) protocol.
- Azure queue storage: it is a storage service that stores messages that can be accessed through HTTP or HTTPS from any part of the globe.
- Disk Storage: It is a virtual hard disk (VHD) and there are two types- managed and unmanaged.
We will cover each of these in this blogs in separate sections below. So, keep reading further to know more about the types and their pricing.
If you have any doubts or queries related to Azure, do post on Azure Community
Azure Blob Storage
Blob stands for Binary Large Object and includes text files, images audios, and videos. Azure Blob is a service that stores massive unstructured data that can be accessed from any place via protocols like HTTP or HTTPS.
Here are Azure blob’s responsibilities:
- Stores files for shared access
- Video and audio streaming
- Stores data for analysis
- Writes to the log file
- Stores data for disaster recovery, backup, and recovery, and archiving
There are three types of blob:
- Block blobs: it is an accumulation of small blocks that have their own unique block ID. One block blob can contain up to 50,000 blocks. You can work parallelly by uploading multiple blocks at a time which decreases upload time. The size of a block blob is slightly higher than the normal 4.75 TB, so it is 100 MB x 50,000 blocks. You can modify the blob by inserting, deleting, and replacing. The unique IDs are exposed in block blobs.
- Append Blobs: even this comprises blocks but when you modify these blobs, new blocks are added at the end. You cannot update or delete any existing blocks and the unique ID is kept a secret, which is not the same as in block blob.
- Page Blobs: they are comprised of 512-byte pages that are optimized for an arbitrary read and write operations. To create a page blob you must first define the maximum size of the blob. You can then add or update the content of page blob. The maximum size of a page blob is 8TB.
Let us now see what all Azure blob offers and at what cost.
Azure Blob storage pricing
The total cost of this service depends on:
- The volume of data stored/month
- What type of operations performed were performed
- How many operations were performed
- Data transfer cost, if any
- Which data redundancy option was selected
Now, before seeing the pricing options, let me briefly explain to you the Data redundancy options in Azure Storage.
|Locally redundant storage (LRS)||Keeps multiple copies of your data in one datacenter. It provides 99.99%(11 9’s) durability over a given year.|
|Zone redundant storage (ZRS)||Keeps multiple copies of your data in different data centers in different regions. It provides 99.99%(12 9’s) durability.|
|Geographically redundant storage (GRS)||Holds multiple copies of your data in one region and replicates to the second region asynchronously. The durability is 16 9’s.|
|Read-access geographically redundant storage (RA-GRS)||Allows read access from the second region which is used for GRS and the read availability is 99.99%. Durability is 16 9’s.|

So, coming back to Azure blob pricing, here are the options when you opt for LRS:
Data Storage Prices (in Rs):
|First 50 TB/month||12.8888/GB||1.3220/GB||1.0576/GB||0.1322/GB|
Data transfer and operations (in Rs) :
|Write Operations (per 10,000)||1.5070||3.3049||6.6097||7.9316|
|List and Create Container Operations (per 10,000)||4.2963||3.3049||3.3049||3.3049|
|Read Operations (per 10,000)||0.1203||0.2644||0.6610||396.5775|

|Data Retrieval (per GB)||Free||Free||0.6610||1.5864|
|Data Write (per GB)||Free||Free||Free||Free|
Let us now move on to the next storage type which is the Azure table.
Azure Table Storage
Azure table storage service stores structured NoSQL data. It is schemaless, meaning the data does not have a fixed structure. You can easily store datasets that do not require any joins or foreign keys. You can denormalize them to make access quicker. You can scale up the tables based on your requirements.
Let us look at its pricing options.
Azure table storage pricing
For storage using Azure table here is the price option:
And for operations and data transfers, it costs Rs. 0.023795/1000 transactions.
Let us quickly see the other storage types, the next being Azure file storage.
Azure File Storage
It provides managed file sharing in the cloud. Applications on Azure can easily share files between the Virtual Machines and is accessible via SMB.
The responsibilities of Azure file storage are:
- Replace on-premise file servers
- It makes lift and shift of application easy to the cloud and offers both, classic as well as hybrid lift and shift
- Cloud development is simplified with diagnostic share, shared application settings, and Dev/Test/Debug.
Let us take a look at the pricing now.
Azure File Storage Pricing
The pricing is with respect to the LRA redundancy option.
Data storage (in Rs):
|GiB/month||9.518/used GiB||3.966/used GiB|
|Snapshots GiB/month||7.932/used GiB||3.966/used GiB|
Operations and data transfer:
|Put, create container operations||0.9915||Free|
|List operations(per 10,000)||0.9915||Free|
|Other operations except for delete (free) per 10,000||0.0992||Free|
|Geo-replication data transfer (per GiB)||N/A||Free|
For file sync, the price is Rs.330.482/month.
I will be now talking about the last primary storage type, Azure Queue. Let us see what it has to offer.
Azure Queue Storage
Azure queue stores a large number of messages that can be accessed from any location using HTTP or HTTPS. The size of a queue message can be up to 64KB.
The uses of Azure queue storage are:
- It creates a backlog of work done and processes asynchronously.
- It carries messages from the Azure web role to the Azure worker role.
Azure storage queue pricing
Data storage option:
|Storage in GB/month||2.9744/GB||3.9658/GB||4.9573/GB|
Operation and data transfer pricing:
|Queue class 1 operations in (10,000)||0.0238||0.0238||0.0238|
|Queue class 2 operations in (10,000)||0.0238||0.0238||0.0238|
|Geo-replication data transfer (per GB)||N/A||Free||Free|
We are finally done discussing the primary storage types. Now, let us see what Disk storage is.
Azure Disk Storage
Azure Disk Storage is further divided into two:
Azure managed disk is a virtual hard disk which is mostly like a physical disk that is virtualized. You can have one storage account for one of each Azure region, which makes it limitless. In unmanaged disk, you need to have storage accounts that can hold the disks for Azure VM.
Managed disks provide you with two kinds of encryption:
- Storage Service Encryption
- Azure Disk Encryption
Without going into further details, let us see the pricing of Disk storage.
Azure Disk Storage Pricing
There are four types of managed disks-
- Ultra SSD Managed Disks
- Premium SSD Managed Disks
- Standard SSD Managed Disks
- Standard HDD Managed Disks
Here are the pricing options for ultra SSD managed disk:
|Disk Size (GiB)||4||8||16||32||64||128||256||512||1024-65536 (in increments of 1 TiB)|
|Throughput Range (MB/s)||1-300||1-600||1-1200||1-2000||1-2000||1-2000||1-2000||1-2000||1-2000|
