can you change azureml rest endpoint from public to private - azure

Is it possible to have private endpoints in azure ml? I want to change the endpoint from public to private

There is a way to make your endpoint private by using a VPN for your workspace
"Azure Private Link enables you to connect to your workspace using a private endpoint. The private endpoint is a set of private IP addresses within your virtual network"
docs has more detail about this - https://learn.microsoft.com/en-us/azure/machine-learning/how-to-configure-private-link?tabs=cli
If it is not possible to use a vpn, another work around could be to deploy your models using azure function apps.
function apps have different levels of authentication and therefore is much more secure then a public endpoint that anyone can access.

How to integrate 2 app services into the same vNet

I have two app services that i want to allow inbound calls only from my vNet. I am able to create a private endpoint and its private dns zone for the first one and it is working. But when i do it for the second one the portal wants me to use the same private dns zone. I cannot choose a different private zone! And if i configure the my second private endpoint through the portal by adding the configuration that links to that second private zone it is getting missconfigured!
Im really stuck in this. My questions are, first Is it possible to integrate two app services into the same vNet?
Second, how can i configure the second private endpoint to be able to work correctly?
Big Thanks to any advice!
I Tried everything to configure that through the azure portal with no luck!
I tried to reproduce the same in my environment like below:
I created two app services to allow inbound calls vNet like below:
App service 1
App service 2
I added outbound traffic of vnet integration like below
I try the same to add my private endpoint with app service 1 it configure successfully with private DNS zone like below:
When I try to add another app service with private endpoint it associates with same private DNS zone only.
Note that: It is not possible to add second private DNS zone within the resource group even I try to add different vnet integration with another app service it associate with same private DNS zone only
Check this similar thread As suggested by Cloudkollektiv you can make use of service endpoint it is similar to private endpoint. It enables private IP addresses in the VNet to reach the endpoint of an Azure service without need for a public IP address on the VNet.

How to access azure function with external application when secured with Private endpoint

We have a requirement where we need to access On Prem SqlServer database from the Azure function. In order to do that we have created a private endpoint.
After creating private endpoint still my function is not able to access On Prem DB, do we need to white list the ipaddress provided in the Private endpoint.
The other problem is we have external solution that is consuming our Azure function which is unable to access it because we have bounded our Azure function with private endpoint, we have issues in release of Azure function as well in CI/CD.
Please suggest how can we solve this.
To fulfill your requirement...
[...] we need to access On Prem SqlServer database from the Azure
function.
... you actually do not need Private Endpoints. Private Endpoints make inbound connections to your Function App private - however, since you need to connect into the other direction - that is from your Function App to your on-premises SQL server - you would need VNET Integration.
See 'How regional virtual network integration works' for details.
Removing the private endpoint and using VNET integration would mean that your Function App remains public (which solves issue #2) but you would be able to access on-premises resources through private IP addresses (and/or internal DNS if required and configured on your VNET).

Is it necessary to create a private DNS zone for private endpoints to PaaS services in Azure?

Right now I'm creating some private endpoints for a number of Azure Storage services. There are two storage accounts, for the first I create a blob endpoint and a queue endpoint. For the second account I create a blob endpoint and a dfs endpoint.
When I try connecting to the endpoints from a machine outside of the VNET using the regular connection strings (that now point to the privatelink resources), I seem to not be able to reach the resource as expected. Trying to connect to it from a VM and an AKS cluster within the same VNET as the private endpoints, I am able to connect.
If these are basically my only use cases, and I'm ok using the default names to connect to the private endpoint resources, is it OK to not create a private DNS zone?
It is a bit unclear to me from the documentation whether this is a necessity.
By using private link you create an endpoint into your vnet/subnet. The private DNS is linked to your vnet and allows you to direct the traffic to that private endpoint (e.g. 10.1.0.4) by using the storage domain.
It's not nessecary to have that private DNS. But that means you'll need to connect directly to private ip address of that endpoint. While that is technically possible you'll likely run into some issues such as the server not knowing which domain is requested without host header and issues with the SSL certificate.
I would therefore recommended always using the private DNS.

App Gateway configuration with Private Endpoint enabled web apps

I am trying to expose my Front End and Function Web Apps using App Gateway. Both of those apps belong to one app service plan.
They are also private endpoint enabled and VNET integrated.
I have databricks in another tenant which needs to feed data to my Function App
So for that reason i need to expose my Function App.
As for the Front End App, it needs to be accessed by all the employees belonging to a particular business unit.
So my question is , when i am configuring listeners, and the backend pool, should i be using the *.privatelink.azurewebsites.net FQDN or the normal *.azurewebsites.net FQDN as the backend pool ?
When you are using Private Endpoint, you already have a CNAME which maps *.privatelink.azurewebsites.net to *.azurewebsites.net and you also have an 'A' record for your private endpoint.
So while configuring App Gateway with Private Endpoint enabled web apps, what is it that you should be using as your backend
You have to use the normal *.azurewebsites.net FQDN instead of the private link one. This normal FQDN automatically resolves to the private link FQDN. The normal FQDN will throw an error when called from a public network when a private endpoint is attached to it because it cannot resolve the private address so your service isn't exposed anymore for the outside world (unless they have public access through your application gateway of course)

How to make all outbounds calls from web app to be private

I've hosted a standard web app in azure that is public. The web app though needs to do outbound requests to resources in a private network that I own. What is the best way to do this? I've read some about hybrid connections, but networking/infrastructure is not my field and just reading about these things makes me kinda scared.
You can use Private Endpoint for your Azure Web App to allow clients located in your private network to securely access the app over Private Link. The Private Endpoint uses an IP address from your Azure VNet address space. Network traffic between a client on your private network and the Web App traverses over the VNet and a Private Link on the Microsoft backbone network, eliminating exposure from the public Internet. Although It does not enable your app to make outbound calls into your network but If you want to have all inbound and outbound in your VNet, then you need to use both Private Endpoint and Regional VNet Integration in two separate subnets.
