Azure Data Factory Private Endpoint Use Case

Question

I have all resources like SQL,ADLSv2,KeyVault, etc. with 'Selected Networks' access and private endpoints. My Azure Data Factory has no private endpoint, but its self-hosted integration runtime (SHIR) is in my vNet in which all other resources (like SQL,ADLS) are present. All linked services from ADF to other resources are 'Test connection=Successful'.

My aim is to make my azure environment secure with non-public access. Will I need a private endpoint on my Data Factory? If yes, why it's necessary, because all linked services are anyways passing. Please give your inputs why (or under which circumstances) ADF/portal private endpoint is necessary?

Microsoft Documentation for ADF private endpoint https://docs.microsoft.com/en-us/azure/data-factory/data-factory-private-link

Thanks in Advance.

Answer 1

If you would like to secure your azure environment with non-public access, then you will have to create a Private Endpoint.

Within a virtual network and subnet, a private endpoint is a private IP address. Set up an Azure Virtual Network as a logical representation of your network in the cloud to shield your Azure resources from assaults in the public network or to allow them to securely interact with one another. Set up IPSec VPN (site-to-site) or ExpressRoute to link an on-premises network to your virtual network (private peering). To run copy activities between a cloud data store and a data store in a private network, or to dispatch transform activities against compute resources in an on-premises network or an Azure virtual network, the Self-hosted Integration Runtime can be installed on an on-premises machine or virtual machine in Virtual Network.

With the assist of Azure Private Link for Azure Data Factory, you could create a Private Endpoint (PE) in your virtual network and allow the non-public connection to particular Azure Data Factory.
