-->Azure Blob storage is Microsoft's object storage solution for the cloud. Blob storage is optimized for storing massive amounts of unstructured data. Unstructured data is data that doesn't adhere to a particular data model or definition, such as text or binary data.
About Blob storage
Blob storage is designed for:
Adding Cache-control to content on Azure Blob storage. All CDN service have the ability to respect whichever cache control directives the origin server sends. Some even require the origin to provide caching headers, as they don't have the capability to set caching policy at the edge. Nov 08, 2019 Azure Storage Blob client library for Java. Azure Blob Storage is Microsoft's object storage solution for the cloud. Blob Storage is optimized for storing massive amounts of unstructured data. Unstructured data is data that does not adhere to a. Page blobs support random access for files stored on them, that is why page blobs are used to store VHDs of Azure Virtual Machines. Append blobs. Append blobs and block blobs are similar to each other and used for append operations like when a new block is created, it will be added to the end of the blob. These are the best choice to dump the logs in a fast and safe way. Creating Azure Blob Storage.
- 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.
Users or client applications can access objects in Blob storage via HTTP/HTTPS, from anywhere in the world. Objects in Blob storage are accessible via the Azure Storage REST API, Azure PowerShell, Azure CLI, or an Azure Storage client library. Client libraries are available for different languages, including:
About Azure Data Lake Storage Gen2
Jul 24, 2015 Upload files to Azure Storage with Azure CLI on Mac July 24, 2015 posted in azure, blob. Normally, I use Visual Studio 2015 Community Edition to browse and manage my blob file but this time I was without my Windows machine and I needed to upload few images into Azure Blob Storage.
Blob storage supports Azure Data Lake Storage Gen2, Microsoft's enterprise big data analytics solution for the cloud. Azure Data Lake Storage Gen2 offers a hierarchical file system as well as the advantages of Blob storage, including:
- Low-cost, tiered storage
- High availability
- Strong consistency

Blob storage resources
Blob storage offers three types of resources:
Azure Blob Storage Api
- The storage account
- A container in the storage account
- A blob in a container
The following diagram shows the relationship between these resources.
Storage accounts
A storage account provides a unique namespace in Azure for your data. Every object that you store in Azure Storage has an address that includes your unique account name. The combination of the account name and the Azure Storage blob endpoint forms the base address for the objects in your storage account.
For example, if your storage account is named mystorageaccount, then the default endpoint for Blob storage is:
To create a storage account, see Create a storage account. To learn more about storage accounts, see Azure storage account overview.
Containers
A container organizes a set of blobs, similar to a directory in a file system. A storage account can include an unlimited number of containers, and a container can store an unlimited number of blobs.
Note
The container name must be lowercase. For more information about naming containers, see Naming and Referencing Containers, Blobs, and Metadata.
Blobs
Azure Storage supports three types of blobs:
- Block blobs store text and binary data, up to about 4.7 TB. Block blobs are made up of blocks of data that can be managed individually.
- Append blobs are made up of blocks like block blobs, but are optimized for append operations. Append blobs are ideal for scenarios such as logging data from virtual machines.
- Page blobs store random access files up to 8 TB in size. Page blobs store virtual hard drive (VHD) files and serve as disks for Azure virtual machines. For more information about page blobs, see Overview of Azure page blobs
For more information about the different types of blobs, see Understanding Block Blobs, Append Blobs, and Page Blobs.
Move data to Blob storage
A number of solutions exist for migrating existing data to Blob storage:
- AzCopy is an easy-to-use command-line tool for Windows and Linux that copies data to and from Blob storage, across containers, or across storage accounts. For more information about AzCopy, see Transfer data with the AzCopy v10 (Preview).
- The Azure Storage Data Movement library is a .NET library for moving data between Azure Storage services. The AzCopy utility is built with the Data Movement library. For more information, see the reference documentation for the Data Movement library.
- Azure Data Factory supports copying data to and from Blob storage by using the account key, a shared access signature, a service principal, or managed identities for Azure resources. For more information, see Copy data to or from Azure Blob storage by using Azure Data Factory.
- Blobfuse is a virtual file system driver for Azure Blob storage. You can use blobfuse to access your existing block blob data in your Storage account through the Linux file system. For more information, see How to mount Blob storage as a file system with blobfuse.
- Azure Data Box service is available to transfer on-premises data to Blob storage when large datasets or network constraints make uploading data over the wire unrealistic. Depending on your data size, you can request Azure Data Box Disk, Azure Data Box, or Azure Data Box Heavy devices from Microsoft. You can then copy your data to those devices and ship them back to Microsoft to be uploaded into Blob storage.
- The Azure Import/Export service provides a way to import or export large amounts of data to and from your storage account using hard drives that you provide. For more information, see Use the Microsoft Azure Import/Export service to transfer data to Blob storage.
Next steps
-->In this quickstart, you learn how to use the Azure portal to create a container in Azure Storage, and to upload and download block blobs in that container.
Prerequisites
To access Azure Storage, you'll need an Azure subscription. If you don't already have a subscription, create a free account before you begin.
Add Dmg To Azure Blob File
All access to Azure Storage takes place through a storage account. For this quickstart, create a storage account using the Azure portal, Azure PowerShell, or Azure CLI. For help creating a storage account, see Create a storage account.
Create a container
To create a container in the Azure portal, follow these steps:
Navigate to your new storage account in the Azure portal.
In the left menu for the storage account, scroll to the Blob service section, then select Containers.
Select the + Container button.
Type a name for your new container. The container name must be lowercase, must start with a letter or number, and can include only letters, numbers, and the dash (-) character. For more information about container and blob names, see Naming and referencing containers, blobs, and metadata.
Set the level of public access to the container. The default level is Private (no anonymous access).
Select OK to create the container.
Upload a block blob
Block blobs consist of blocks of data assembled to make a blob. Most scenarios using Blob storage employ block blobs. Block blobs are ideal for storing text and binary data in the cloud, like files, images, and videos. This quickstart shows how to work with block blobs.
To upload a block blob to your new container in the Azure portal, follow these steps:
In the Azure portal, navigate to the container you created in the previous section.
Select the container to show a list of blobs it contains. Since this container is new, it won't yet contain any blobs.
Select the Upload button to open the upload blade
Browse your local file system to find a file to upload as a block blob
Optionally, expand the advanced section to define other setting such as authentication type, access tier, or virtual folder path.
Select the Upload button to commit the upload
Upload as many blobs as you like in this way. You'll see that the new blobs are now listed within the container.
Download a block blob
You can download a block blob to display in the browser or save to your local file system. To download a block blob, follow these steps:
- Navigate to the list of blobs that you uploaded in the previous section.
- Right-click the blob you want to download, and select Download.
Clean up resources
To remove the resources you created in this quickstart, you can delete the container. All blobs in the container will also be deleted.
To delete the container:
Add Dmg To Azure Blob File
- In the Azure portal, navigate to the list of containers in your storage account.
- Select the container to delete.
- Select the More button (...), and select Delete.
- Confirm that you want to delete the container.
