Connectivity from IaaS(VM) and PaaS service(ADF) to ADLS account with public network access disabled
In this blog post, we will investigate the impacts of disabling public network access in the storage account and learn how to establish connections to an Azure Data Lake Storage account from both IaaS (Virtual Machine) and PaaS services (Azure Data Factory), when public network access is disabled. Additionally, we will address common troubleshooting issues that may arise due to this configuration.
Introduction
Azure storage accounts provide a scalable and secure way to store and access data in the cloud. This model enables you to control the level of access to your storage accounts that...
Azure Storage supports for Secure File Transfer (SFTP) protocol in Azure Storage Account. We can use a SFTP client to securely connect to the Blob Storage endpoint of your Azure Storage account, and then perform upload and download operations over the account. Please note that SFTP feature support is only available for hierarchical namespace (ADLS Gen2) enabled accounts.
In this article, we will discuss about how to troubleshoot and isolate connectivity issues to SFTP storage account from your machine to understand whether this is due to port blockage, firewall issues, connectivity using...
Ensuring adequate access control is of utmost importance for effectively safeguarding your Azure Storage assets. The Access Control Lists (ACLs) of your Azure Storage Account assume a pivotal role in establishing permissions for both containers and blobs situated within the storage account. The inheritance of ACLs is already in place for newly generated child items beneath a parent directory. However, it's noteworthy that now you also have the capability to set, update, or remove ACLs recursively for the pre-existing child items of a parent directory, thereby eliminating the need to...

Scenario:
This article explains step by step procedures to accomplish the requirements in Azure Storage using built in RBAC roles:
Read/Download and write/upload operation for containers and blobs should be allowed for the users.
Delete operations should be restricted.
Pre-Requisites:
Azure Storage GPV2 / ADLS Gen 2 Storage account
Make sure to have enough permissions(Microsoft.Authorization/roleAssignments/write permissions) to assign roles to users , such as Owner or User Access...
Symptoms:
Uploading files using Java SDK class DataLakeFileClient fails to initiate the ADF trigger.
Uploading files using Azure Portal initiates the trigger as expected.
ADF trigger is configured to ignore empty blobs.
Analysis:
Whenever a file is created using ADLS Gen2 REST API, there are 3 operations called at the backend i.e. CreateFile, AppendFile and FlushFile.
Microsoft.Storage.BlobCreated event is triggered when a blob is created or replaced. Specifically, this event is triggered when clients use the CreateFile and FlushWithClose operations that are available...
Background
This article describes how to get container level stats in Azure Blob Storage, and how to work with the information provided by blob inventory.
The approach presented here uses Azure Databricks and is most suited to be used in storage accounts with a huge amount of data.
At the end of this article, you would be able to create a script to calculate:
The total number of blobs in the container
The total container capacity (in bytes)
The total number of snapshots in the container
The total container snapshots capacity (in bytes)
The total number of versions in the...
Background:
Many times, we have a requirement to delete the older logs from $logs as the Retention days as it was not supported for ADLS gen2 storage account.
Please note Product team already worked on this fix and in case automatic deletion is not working can follow the below steps
Please refer to article https://docs.microsoft.com/en-us/azure/storage/common/manage-storage-analytics-logs?tabs=azure-portal#modify-log-data-retention-period for more information
Deletion of logs from the $logs can be achieved from the following options
Azure Storage explorer
