Why does external I.P. need access to on-prem sql database when copying data with ADF to Azure SQL?
It looks like on-prem sql makes a direct connection to Azure SQL (bypassing ADF). Is this by design or do I follow the wrong workflow?
Data Factory use the integration runtime to help us create the connection to the Source/Sink dataset. Azure integration runtime for cloud dataset and Self-host integration runtime for on-premise source/sink dataset.
The integration runtime (IR) is the compute infrastructure that Azure
Data Factory uses to provide data-integration capabilities across
different network environments. For details about IR, see Integration
runtime overview.
A self-hosted integration runtime can run copy activities between a
cloud data store and a data store in a private network. It also can
dispatch transform activities against compute resources in an
on-premises network or an Azure virtual network. The installation of
a self-hosted integration runtime needs an on-premises machine or a
virtual machine inside a private network.
Azure integration runtime is provides by ADF in default. The self-host integration runtime must be created manually.
That means Data Factory can not access the on-prem SQL database directly. It need the self-host integration runtime to help us connect to the on-prem SQL database.
It means that the on-prem sql does not make a direct connection to Azure SQL(bypassing ADF. That why external I.P. need access to on-prem sql database when copying data with ADF to Azure SQL.
HTH.

Requirement: I wanted to copy data from a specific table/view residing on a on-premise SQL Server to Azure SQL DB.
Infrastructure: As depicted in below picture. Essentially, the Azure network is directly connected with corporate network over Express Route. Thus it's a pure private network connection; as good as the corporate network itself.
Issue/Question: I know there are multiple approaches present to get this operation done and I am not restricted to use ADF copy Data tool only. BUT, for all of these I see some cavets or extra steps needed to be done as below:
ADF Copy Data Tool: Needs a SH-IR and a small MSI package needs to be installed on on-premise machine which hosts the SQL server for registration purpose.
Logic Apps: Needs a Virtual Gateway (OR) ASE
App Service: If the operation is wrapped in a C# application and I choose to deploy to a Azure Web Apps. Then in-order to connect to on-premise SQL Server we need to setup hybrid connection manager and as in #1 we need to install something in on-premise machine.
For my case, none of these extra steps can be done. essentially, the on-premise SQL Server comes under a different BU and thus I don't have any permission there; except they have given grant to a table/view. Thus, none of these extra shitty steps can be done.
Moreover, as mentioned above; since it's connected over express route as direct connection, As can be seen in above picture, both the on-premise and azure SQL are essentially inside the same corporate network. THUS, I should be able to access them directly without configuring any of these extra steps as mentioned above.
Please confirm on these and provide a suggestion.
Thank You.
You can still go with the ADF scenario without a SHIR by creating ADF in a Managed VNET using Private Endpoint. As you already have an ER circuit and have the flexibility to configure the Azure side, can you do this with Azure IR: Access on-premises SQL Server from Data Factory Managed VNet using Private Endpoint - Azure Data Factory | Microsoft Docs
There are 2 solutions which could work for your scenario but even for them to work ,you would need access to on prem SQL server machine access to some extent atleast for one time config and Azure SQL db should be accessible via SSMS installed on on-prem machine.
Using linked server
You can create a linked server ( process explained here https://www.sqlshack.com/create-linked-server-azure-sql-database/ ) on on-prem server and create a agent server job to insert data to azure SQL db table.
Via Python Script
This would need Python installation on on-prem machine. Once installed you can write script to transfer data between on-prem SQL server and Azure SQL db. You can schedule this script again by using an agent server job.
I am receiving multiple .trn files on daily basis & I am resorting those file in on-premises sql database. Now How we can migrate those .trn files daily on azure.
Connect on-premises SQL database to Azure data factory using Self hosted IR. A self-hosted integration runtime can run copy activities between a cloud data store and a data store in a private network.
Create pipeline and use copy activity.
Select on-premises SQL database as Source.
Select Azure service of your choice as Sink.
Now use trigger to copy data from on premise to Azure periodically.

What is the best method to sync medical images between my client PCs and my Azure Blob storage through a cloud-based web application? I tried to use MS Azure Blob SDK v18, but it is not that fast. I'm looking for something like dropbox, fast, resumable and efficient parallel uploading.
Solution 1:
AzCopy is a command-line tool for copying data to or from Azure Blob storage, Azure Files, and Azure Table storage, by using simple commands. The commands are designed for optimal performance. Using AzCopy, you can either copy data between a file system and a storage account, or between storage accounts. AzCopy may be used to copy data from local (on-premises) data to a storage account.
And also You can create a scheduled task or cron job that runs an AzCopy command script. The script identifies and uploads new on-premises data to cloud storage at a specific time interval.
Fore more details refer this document
Solution 2:
Azure Data Factory is a fully managed, cloud-based, data-integration ETL service that automates the movement and transformation of data.
By using Azure Data Factory, you can create data-driven workflows to move data between on-premises and cloud data stores. And you can process and transform data with Data Flows. ADF also supports external compute engines for hand-coded transformations by using compute services such as Azure HDInsight, Azure Databricks, and the SQL Server Integration Services (SSIS) integration runtime.
Create an Azure Data Factory pipeline to transfer files between an on-premises machine and Azure Blob Storage.

We are supporting a legacy system for our organisation. In the current scenario, we receive a SQL Server backup (.bak files) from the application vendor on an FTP location. For every weekend on Sunday it is a Full backup and for every other day its the differential one.
On our side, we have a SQL server instance running which has custom stored procedures written and scheduled to check the location every morning and then restore the backups every day. These restored backups are then used by the organisation for internal reporting purposes. There are 100s of other stored procedures written for different reports in different DBs on the same instance.
Since SQL Server 2008 is now out of support and for cost-saving purposes of running on-premise system, my team has been given a task to look into migrating this whole system to Azure SQL database.
My question is what is the most effective way in which we can move this workflow to the cloud? I have an azure trial account set up for me to try but haven't been successful in restoring the .bak files on Azure SQL instance.
Thanks.
You essentially have two options for Azure, either perform a fairly linear Lift and Shift to SQL Server on an Azure VM or go with a more advanced Azure PaaS offering in Azure SQL Database Managed Instance. The specific deployment Azure SQL Database (Single Instance) will not support your current solution requires with regard to the .bak file support, and I have detailed that below. For further details between the difference between Azure SQL Database Single Instance versus Managed Instance, please see: Features comparison: Azure SQL Database and Azure SQL Managed Instance
The second option, is to leverage the Azure Enterprise Ready Analytics Architecture (AERAA) (link) of Azure (PaaS) Analytics services. With Azure SQL Database (PaaS) services, as opposed to on-premise SQL Server or SQL Server on an Azure VM, there is no Integration Runtime or Analysis Services as a bundled service component. These services are separate PaaS offerings and with the help of the linked AERAA blog, you can gain a better understanding of the Azure Analytics services.
The .bak versus .bacpac support dilemma:
Since the main requirement for your solution is support of .bak files, you need to understand where .bak and where .bacpac files are supported. The term Azure SQL Database applies to both a specific deployment option for an Azure SQL database (PaaS) service and as a general term for Azure SQL cloud databases. As for the specific deployment option, Azure SQL Database (Single Instance nor Elastic Pools) will support your scenario with .bak files. This deployment option will support export/import functionality via .bacpac file format. It will not support full/partial restore functionality. The backup/restore functionality although configurable, is only in scope for the specific database hosted by an Azure SQL (logical) Server instance. Basically, you can not restore an external file. You can import, which is always a full copy. So, for that reason, for an Azure PaaS database service you will need Azure SQL Database Managed Instance for .bak file support or deploy an SQL Server VM image to an Azure VM, and migrate your objects via Azure Database Migration Service.

I have hard time with Azure Functions on Azure Government. I need to create a C# trigger bases process on Azure Storage. The goal is to automate the process of the loading the files into Azure SQL DB when a file is dropped into Azure Storage.
Since Azure Functions in Azure Government are not fully comparable to Azure Function in regular Azure and not all UIs are the same, I can't deploy the function to trigger on a storage file.
I was able to build the process in regular Azure Cloud following instructions from https://github.com/yorek/AzureFunctionUploadToSQL but since Azure Government is missing the UI for Azure Functions I'm having hard time to replicating the process in Azure Government.
Portal UI support is not yet available in Azure Government, but it is coming soon. Additionally, Azure Government currently supports "App Service plan" ("Consumption plan" coming soon).
In the meantime, you can do everything you need. First, provision your Azure Function in Azure Gov via the Azure CLI by following this Quickstart example for Functions on Azure Gov. That same link also shows you how you can use Visual Studio to set up your triggers (in your case, a Blob trigger).
Once complete, deploy your Function to Azure Gov with Visual Studio.
