Microsoft Azure Storage options overview

This post outlines the available storage options in Azure portal , creating blob data and accessing it through Azure storage explorer or using C# code. The code discussed in this post can be downloaded from here

Microsoft offers following storage options


Creating a Storage account in AZURE portal

Login to Azure Portal to create a new storage account


Storage account name – The name must be unique and should contain only lower case letters and numbers.

Location – Select the desired data center location. example: East US

Performance – Two options to choose  standard vs premium. Choose Standard if your application require  bulk-storage or where data is accessed in-frequently. Standard option stores data in magnetic tapes. Choose Premium option if your application involve high-intense I/O operations. Example: data base operations. Premium storage accounts can only be used with Virtual Machine(VM) disks.  Premium account stores data in Solid-State drives. You wouldn’t be able to change the performance option for storage account once you select premium.

Account Kind – Select general purpose account kind to store Blobs, Tables , Files and Queues. BlobStorage specifically for Blob data.


StorageV2 option recently added to portal. Difference between Storage and StorageV2 is, you wouldn’t see access tier option when you select storage.

What is access tier? This can only set at Blob data level not account level. You have two options Hot Access tier(for frequently accessed data) and Cool Access tier(for in-frequently accessed data).

Replication – The data in Azure Storage is always replicated for high-availability. Choose a replication strategy based on your durability choice


Creating BLOB Data storage

Navigate to storage account that you have created in above step. click BLOB from services


Create a container to store data


How to upload files to BLOB storage account?

Files can be added to BLOB storage using AZURE Storage explorer or through code. First lets upload file using AZURE Storage Explorer.

Open storage explorer and login with your azure account credentials and navigate to the BLOB storage account that you have just created.


You can create new folders inside BLOB container and upload files.

Access BLOB storage account files in ASP.NET Core application

create a core web application and use connected service to connect to Azure Storage account by right click your project then Add then say Connected Service



It installs all required NuGet package for AZURE Storage and connection string to your appsettings.json file. Following code helps to retrieve all files inside container and display in page.

Display images from BLOB storage

First get the BLOB container reference with below code snippet

List images by using BlobResultSegment reference  



To display images in view write following code in view

How to upload files to Storage account?


You can manage and access the data in Azure Storage with REST APIs. REST API reference
If you do not see the retrieved image or file then you need to give container public accessible permission to your app through portal or code. You can also use storage explorer to give permissions , click set public access level
you can set the above using following line of code
await blobContainer.SetPermissionsAsync
(new BlobContainerPermissions 
{ PublicAccess = BlobContainerPublicAccessType.Blob });
if you do not want to give public read access to blob container then you can choose the option shared access signature. More about using shared access signature in accessing storage account can refer here
