Azure Blob Storage allows you to store large amounts of unstructured object data. You can use Blob Storage to gather or expose media, content, or application data to users. Because all blob data is stored within containers, you must create a storage container before you can begin to upload data. To learn more about Blob Storage, read the Introduction to Azure Blob storage.
Any client that possesses a valid SAS can access data in your storage account as permitted by that SAS. It's important to protect a SAS from malicious or unintended use. Use discretion in distributing a SAS, and have a plan in place for revoking a compromised SAS.
Although your policy is now displayed in the Stored access policy table, it is still not applied to the container. If you navigate away from the Access policy pane at this point, the policy will not be saved or applied and you will lose your work.
A container lease is used to establish or manage a lock for delete operations. When a lease is acquired within the Azure portal, the lock can only be created with an infinite duration. When created programmatically, the lock duration can range from 15 to 60 seconds, or it can be infinite.
Following the steps below may permanently delete containers and any blobs within them. Microsoft recommends enabling container soft delete to protect containers and blobs from accidental deletion. For more info, see Soft delete for containers.
In some cases, it's possible to retrieve containers that have been deleted. If soft delete data protection option is enabled on your storage account, you can access containers deleted within the associated retention period. To learn more about soft delete, refer to the Soft delete for containers article.
This video provides an introduction to Azure Container Storage, an end-to-end storage management and orchestration service for stateful applications. See how simple it is to create and manage volumes for production-scale stateful container applications. Learn how to optimize the performance of stateful workloads on Azure Kubernetes Service (AKS) to effectively scale across storage services while providing a cost-effective container-native experience.
Azure Container Storage utilizes existing Azure Storage offerings for actual data storage and offers a volume orchestration and management solution purposely built for containers. You can choose any of the supported backing storage options to create a storage pool for your persistent volumes.
Until now, providing cloud storage for containers required using individual container storage interface (CSI) drivers to use storage services intended for IaaS-centric workloads and make them work for containers. This creates operational overhead and increases the risk of issues with application availability, scalability, performance, usability, and cost.
Azure Container Storage is derived from OpenEBS, an open-source solution that provides container storage capabilities for Kubernetes. By offering a managed volume orchestration solution via microservice-based storage controllers in a Kubernetes environment, Azure Container Storage enables true container-native storage.
Accelerate VM-to-container initiatives: Azure Container Storage surfaces the full spectrum of Azure block storage offerings that were previously only available for VMs and makes them available for containers. This includes ephemeral disk that provides extremely low latency for workloads like Cassandra, as well as Azure Elastic SAN Preview that provides native iSCSI and shared provisioned targets.
Customers running stateful container applications today face multiple challenges including scaling bottlenecks, complexity of configuration or management, and high cost - due to retrofitted storage solutions, or the need to custom deploy and self-manage open-source options. With Azure Container Storage, you can now leverage different block storage options via a consistent, unified, and fully managed experience optimized for your workload.
The pricing for Azure Container Storage is simply comprised of two components: the cost of the underlying storage you use, and a service fee for Azure Container Storage orchestration. During the preview period, Azure Container Storage orchestration is offered for free for container storage pools deployed of any size, no service fee, and you only pay for the underlying storage resources consumed.
Azure Storage (opens new window) is a versatile and secure storage service. You can create storage containers with folder hierarchies and store Blobs (opens new window) in them. But it isn't very straightforward to move Blobs between containers or between storage accounts. Azure offers several options to help with this, including Azure Storage Explorer (opens new window).
Once you have properly configured credentials to access your Azure storage container, you can interact with resources in the storage account using URIs. Databricks recommends using the abfss driver for greater security.
Accessing Azure blob storage in government regionsusing a storage integration is limited to Snowflake accounts hosted on Azure in thesame government region. Accessing your blob storage from an account hosted outsideof the government region using direct credentials is supported.
Generate a shared access signature (SAS) token to grant Snowflake limited access to objects in your storage account. You can then access an external (Azure) stage that references the container using the SAS token.
This section describes how to use storage integrations to allow Snowflake to read data from and write data to an Azure container referenced in an external (Azure) stage. Integrations are named, first-class Snowflake objects that avoid the need for passing explicit cloud provider credentials such as secret keys or access tokens. Integration objects store an Azure identity and access management (IAM) user ID called the app registration. An administrator in your organization grants this app the necessary permissions in the Azure account.
Create a storage integration using the CREATE STORAGE INTEGRATION command. A storage integration is a Snowflake object that stores a generated service principal for your Azure cloud storage, along with an optional set of allowed or blocked storage locations (i.e. containers). Cloud provider administrators in your organization grant permissions on the storage locations to the generated service principal. This option allows users to avoid supplying credentials when creating stages or loading data.
A single storage integration can support multiple external (i.e. Azure) stages. The URL in the stage definition must align with the Azure containers (and optional paths) specified for the STORAGE_ALLOWED_LOCATIONS parameter.
Storage Blob Data Contributor grants read and write access. This allows loading data from or unloading data to files staged inthe storage account. The role also allows executing the REMOVE command to remove files staged in thestorage account.
Snowflake caches the temporary credentials for a period that cannot exceed the 60 minute expiration time. If you revoke access from Snowflake, users might be able to list files and load data from the cloud storage location until the cache expires.
For example, set mydb.public as the current database and schema for the user session, and then create a stage named my_azure_stage. In this example, the stage references the Azure container and path mycontainer1/path1, which are supported by the integration. The stage also references a named file format object called my_csv_format:
The STORAGE_INTEGRATION parameter is handled separately from other stage parameters, such as FILE_FORMAT. Support for these other parameters is the same regardless of the integration used to access your Azure container.
The following example uses SQL to create an external stage named my_azure_stage that includes Azure credentials and amaster encryption key. The stage URL references the Azure myaccount account. Thedata files are stored in the mycontainer container and /load/files path. The stage references a named file format object calledmy_csv_format. Note that the example truncates the MASTER_KEY value:
Alternatively, you can instantiate a BlobServiceClient using the fromConnectionString() static method with the full connection string as the argument. (The connection string can be obtained from the azure portal.) [ONLY AVAILABLE IN NODE.JS RUNTIME]
Alternatively, you instantiate a BlobServiceClient with a StorageSharedKeyCredential by passing account-name and account-key as arguments. (The account-name and account-key can be obtained from the azure portal.)[ONLY AVAILABLE IN NODE.JS RUNTIME]
A blob container is similar to a directory in a file system which organises the blobs. A storage account can include an unlimited number of containers, and a container can store an unlimited number of blobs.
This article was designed to complement the information available in the Veeam Backup & Replication User Guide, specifically the required storage account and container settings to align with the Azure Blob Storage Immutability Limitations.
Incorrect configuration of the storage account and its container can prevent Veeam Backup & Replication from managing immutability, which would necessitate the creation of a new storage account and container with the correct settings.
Create a storage container using Microsoft Azure Portal, Microsoft Azure CLI, or Microsoft Azure Storage Explorer. Keep a note of the storage account name, storage account key and container name.
Test your Azure applications with the Azurite open-source emulator. For testing purposes, the xbcloud binary adds the --azure-development-storage option that uses the default access_key and storage account of azurite and testcontainer for the container. You can overwrite these options, if needed.
A container serves as a default container for your storage account. A storage account may have one container container. A blob stored in the container container may be addressed without referencing the container container name. For more information, see Azure Blob container.
