I am a new user of the Azure platform, and am having trouble understanding how differents parts are conected. I have data in a Storage blob that I would like to use to make HTTPS POST requests to a web service. My question therfore is as follows: How can I send data from my Azure storage blob to a REST API endpoint?
First, let's start with a little background:
Azure Resource Manager (ARM)
ARM is the REST API that you interface with, using the Azure Portal, PowerShell module, or cross-platform (xPlat) CLI tool, in order to provision and manage cloud resources inside your Azure subscription (account). In order to provision resources, you must first create a Resource Group, essentially a management container for various cloud resource instances.
Azure Storage (Blob)
Microsoft Azure Storage offers several different services:
Blob (unstructured, flat data storage)
Files (cloud-based SMB share for Azure VMs)
Queue (FIFO / LIFO queues, similar to Azure Service Bus)
Table (NOSQL partitioned storage)
Of these types of storage, Blob storage is arguably the most common. In order to utilize any of these storage services, you must first provision a Storage Account inside an ARM Resource Group (see above). To specifically utilize blob storage, you create a Blob Container inside your Storage Account, and then create or upload blobs into this container(s). Once data is stored in an Azure Blob Container, it does not move unless a service explicitly requests the data.
Azure App Service
If you're deploying a Web App (with a front end) or a REST API App (no front end), you'll be using Microsoft Azure's App Service offering. One unique feature of Azure App Service's Web App (I know, it's a mouthful) offering is WebJobs. WebJobs essentially allow you to run arbitrary code in the cloud, kind of like a background worker process. You can trigger WebJobs when blobs are created or uploaded, using this document.
Essentially, you use the [BlobTrigger()] .NET attribute, from the Azure WebJobs SDK, to designate code that will be executed inside Azure WebJobs whenever a new blob is created. The code that executes could grab the blob data, and send it off to your REST API endpoint.

I've created new ADF instance on Azure with Managed Virtual Network integration enabled.
I planned to connect to Azure Key Vault to retrieve credentials for my pipeline’s source and sink systems using Key Vault Private Endpoint. I was able to successfully create it using Azure Data Factory Studio. I have also created Azure Key Vault linked service.
However, when I try to configure another Linked Services for source and destination systems the only option available for retrieving credentials from Key Vault is AVK Linked Service. I'm not able to select related Private Endpoint anywhere (please see below screen).
Do I miss something?
Are there any additional configuration steps required? Is the scenario I've described possible at all?
Any help will be appreciated!
UPDATE: Screen comparing 2 linked services (one with managed network and private endpoint selected and another one where I'm not able to set this options up):
Managed Virtual Network integration enabled, Make sure check which region you are using unfortunately ADF managed virtual network is not supported for East Asia.
I have tried in my environment even that option is not available
So, I have gathered some information even if you create a private endpoint for Key Vault, this column is always shown as blank .it validates URL format but doesn't do any network operation
As per official document if you want to use new link service, instead of key vault try to create other database services like azure sql, azure synapse service like as below

I have deployed an API with certain business logic in AKS. The load balancer type is internal. I am able to access this within AKS cluster. on the below address
http:servicename/myapi/
But I want to call this API from an ADF pipeline. How can I do that? What are the configurations I should do to be able to call this API from ADF?
You have to use Web Activity to make Rest API call from Azure DataFactory Pipeline.
An Azure Data Factory may be used to call a custom REST endpoint
through Web Activity. You can send datasets and connected services to
the activity to be consumed and accessed.
Note : By utilizing self-hosted integration runtime, Web Activity may also invoke URLs that are hosted on a private virtual network. The URL endpoint should be visible to the integration runtime.
Please check below documentation to know more about web activity : Web Activity in Azure Datafactory.
I am using an open source tool for deployment of schema for my warehouse snowflake. I have successfully done it for tables, views and procedures. Currently I'm facing an issue, I have to deploy snowflake stages same way. But stages required url and azure saas token when you define it in your sql file like this:
CREATE or replace STAGE myStage
URL = 'azure://xxxxxxxxx.blob.core.windows.net/'
CREDENTIALS = ( AZURE_SAS_TOKEN = 'xxxxxxxxxxxxxxxxxxxx' )
file_format = myFileFormat;
As it is not encouraged to use your credentials in file that will be published on version control and access by others. Is there a way/task in azure devOps so I can just pass a template SQL file in repo and change it before compilation and execution(may be via azure key vault) and change back to template? So these credentials and token always remain secure.
Have you considered using a STORAGE INTEGRATION, instead? If you use the storage integration credentials and grant that to your Blob storage, then you'd be able to create STAGE objects without passing any credentials at all.
https://docs.snowflake.net/manuals/sql-reference/sql/create-storage-integration.html
For this issue ,you can use credential-less stages to secure your cloud storage without sharing secrets.
Here agree with Mike, storage integrations, a new object type, allow a Snowflake administrator to create a trust policy between Snowflake and the cloud provider. When Snowflake connects to the organization’s cloud storage, the cloud provider authenticates and authorizes access through this trust policy.
Storage integrations and credential-less external stages put into the administrator’s hands the power of connecting to storage in a secure and manageable way. This functionality is now generally available in Snowflake.
For details ,please refer to this document. In addition, you can also via azure key vault, key vault provides a secure place for accessing and storing secrets.
I set up an area in Azure that contains a cloud service, storage accounts, and a webapp. I need to move that to a separate subscription.
I know how to do that but my question is, is there an order that I need to follow when moving all the resources?
When I go directly to the cloud service and click Move to a new subscription it tells me it can't do that because it's a classic service. I'm guessing it's because I have a classic storage account under that service along with a RM storage account as well so I need to move those first?
In Amazon cloud API there is the possibility to get identity data, meaning data from the running instance - on which region it is, dns ....
is there the same option in Azure? as I am creating management system in which the server is installed on a virtual machine and I need to know to which region it is related, all this using REST API
In Azure you can use Azure API Management REST API to get all sort of information for Azure:
ex:
Lists all of the resources in a subscription:
https://management.azure.com/subscriptions/{subscription-id}/resources?$top={top}$skiptoken={skiptoken}&$filter={filter}&api-version={api-version}
For the complete documentation look at this page here:

You can do similar things using Powershell scripts as well.
