If the two VNETs are peered, can a client in one VNET sitting in one Azure Subscription use Private Endpoint to a resource in another VNET setting in separate Azure Subscription?
Essentially, I am asking if Private Endpoints can be used across Azure subscriptions?
Of course Yes. You can see the description here:
The private endpoint can be reached from the same virtual network,
regionally peered VNets, globally peered VNets and on premises using
private VPN or ExpressRoute connections.
From this, it means the private endpoint can be reached from the globally peered VNets. And here is also a description for the global peering of VNet:
The ability to transfer data between virtual networks across Azure
subscriptions, Azure Active Directory tenants, deployment models, and
Azure regions.
So finally, the conclusion according to the two descriptions is that the private endpoint can be accessed across different subscriptions.

I have a vnet in azure and some app services which are for now all share the same location, but in future I may be adding app services which haven't the same region as the vnet so I was wondering is this will make a problem if I want to connect to the vnet ( as they are not included in the vnet ) ?
I will be grateful for your explaination and your time
I have never tried it, but according to this documentation, it should work to setup a private endpoint in a vnet in another region than the app service.
"You can also deploy the Private Endpoint in a different region than the Web App"
And
"You can enable multiple Private Endpoints in others VNets and Subnets, including VNets in other regions."

I would like to know few things about my web apps hosted in Central US connecting to Azure SQL FO group connection string. The Primary SQL is hosted in the same region which is Central US and the Secondary Replica is hosted in East US 2.
I am considering using Private Link for Azure SQL.So in order for my web app to talk to the Azure SQL over the private endpoint, i have to enable regional VNET integration for my Web App as i read in MS Docs.
So at the moment i have two subnets in Central US and one of the subnets i have to dedicate for creating VNET integration for my Web Apps. The other subnet will be hosting my SQL Private Endpoint.
I have already enabled Global VNET peering between Primary Central US and the Secondary VNET in East US 2.
So i would like to know whether during a disaster and after a failover happens for my SQL from Primary Central US to secondary East US 2, will my Web Apps automatically connect to the SQL FO group read/write listener after i enable private link for my Azure SQL.
I don't understand what it means by this below as per the link :
https://learn.microsoft.com/en-us/azure/architecture/example-scenario/private-web-app/private-web-app
Global peering
Any service in any Azure region that can connect through the Virtual Network can reach the database's private endpoint, for example through Virtual Network peering in hub-and-spoke topologies. However, for App Service regional VNet Integration, the peered Virtual Networks must be located in the same Azure region.
As per the line "However, for App Service regional VNet Integration, the peered Virtual Networks must be located in the same Azure region.", my peered virtual network is from Central US to East US 2 which is like Global Peering.
So how this statement applies to in my case.
Looking forward to some pointers
Is it possible to use a Private endpoint between two services -
In different VNETs
VNETs are in different subscriptions and VNETs have not peered
Subscriptions are in different Tenant
On similar lines, it seems, Private Link could also support the same - Support for across VNET sharing. Extract below -
"
Privately access services on the Azure platform: Connect your virtual network to services in Azure without a public IP address at the source or destination. Service providers can render their services in their own virtual network and consumers can access those services in their local virtual network. The Private Link platform will handle the connectivity between the consumer and services over the Azure backbone network"

In this case, I don't think it's possible without VNet peered.
After my validation, we can access the service in different subscriptions and different tenants with private endpoint and VNet to VNet peering enabled in each VNet.
In subA and TenantA, I created
VNetA and one Azure VMa without public IP deployed in that VNet. We can access the VM with a bastion host in that VNet. Refer to this.
In subB and TenantB, I create
a storage account and a private DNS zone privatelink.file.core.windows.net and a VNetB.
Enable the private endpoint for this storage account and storage subresource file, you may refer to this
Note, we should link the VNetA and VNetB in the same private DNS zone, then we can get the file share FQDN resolved to the private IP address from the Azure VMa. Also, we should use an account having enough permission on both subscriptions.
If without the VNet peering, the network connecting is blocked because the VNet A and VNet B belong to different isolation virtual networks and there is no routing from VNet A and VNet B.
If the VNet peering at each other, the network connecting is successful.
It's perfectly possible, works Private Endpoints works just fine across subscriptions and tenants. You just need to create them slightly differently. Create them from the destination side, then on the Resource page select "Connect to an Azure resource by resource ID or alias.". And paste the resource id you are connecting to. Resource ID can be obtained on the resource overview page - JSon link.
One it's done - go to the source->private endpoints and manually approve requested private endpoint.
When selecting Connect to an Azure resource by resource ID or alias, what's not very clear are the actual values for Resource ID or alias(2) and Target sub-resource(3).
In this example, I am referencing a storage account and file share.
Resource ID or alias = Resource ID of the storage account. e.g:
/subscriptions/aaaaa-1111-11111-aaaa-asasdas212/resourceGroups/myresourcegroup/providers/Microsoft.Storage/storageAccounts/mystorageaccount
Target sub-resource is the name of the sub-resource from the following list:

Is it possible to create an Azure Bastion service within one subscription (a hub subscription for example), and connect to VMs within a spoke subscription where the VNETs are peered together? The peered VNets all exist in the same region as the hub, and Bastion Service.
Currently, It's not possible.
You could vote up this feature request and MSFT is planning for it.
Let's take the following scenario:
I have a resource group in the East Region with 1 VM
I have a resource group in the West Region with 1 VM
Both of these VMs are only accessible via Private IP addresses. RDP via Public IP address is not an option. One would assume that in order for me to RDP to these machines, I would have to VPN into Azure's gateway first. However, I don't want to create a virtual gateway in every single resource group.
Is it possible for me to vpn into one resource (in one resource group), and access all of the machines in all other resource groups?
Yes, It's possible to do this with VNet peering(connecting VNets within the same Azure region). You could follow this to implement a hub-spoke network topology in Azure. In this case, the hub VNet is a peering VNet with allow gateway transit enabled and the spoke VNet is a peering VNet with use remote gateways enabled.
please note that you cannot use remote gateways or allow gateway transit with global peering(connecting VNets across Azure regions). Refer to requirements and constraints about global peering.
To use remote gateways or allow gateway transit, peered virtual
networks in must be in the same region.
so you have to move the peering VNets in the same region if the two VNets in each resource group are not in the same region.
Another option will create a separate VPN gateway in another resource group but this is not your expectation. Note that
A Point-to-Site client can only connect to resources in the VNet in
which the virtual network gateway resides.
Refer to VPN gateway FAQ.
You can use vnet peering with Use remote gateways checkbox enabled. You need to peer the vnets together and check use remote gateways on the second vnet (one without gateway).
