Great video, you explain the concept very well. Thank you. It's too bad that Private Endpoints alone can't accomplish App Service to VNet connectivity... I fail to understand why so many Azure service require their own dedicated subnets. My organization is on an ASE, and to avoid potential resource contention we decided early on to stick each Web / Function App on it's own ASP for independent scalability. So we have about 100 ASPs across all environments at this point. My latest venture was to cut our App Service spend by moving away from the ASE and onto Private Endpoints with VNet integration, but I made the unfortunate discovery that each ASP requires it's own subnet for VNet integration. Back to the drawing board I guess

Thank you John, as always awesome! I was able to integrate my database & app service using a combination of VNet/Private Endpoint and Regional VNet Integration, works fine. But got some issues/questions when I tried to access my database not using the IP but the DNS name instead. Still learning a lot, not sure I fully understand how VNet's integrated with azure private DNS zones and what exactly magic settings WEBSITE_DNS_SERVER and WEBSITE_VNET_ROUTE_ALL does. I actually did manage to connect to the database when I set these 2 settings but the second one sounds dangerous ad we have outbound traffic that mu go to the internet

Hi! Thanks a lot for this video, (and all the others I've watched!). Please may I ask a question? I have an V1P2 App Service plan with a single app deployed. I can reach it via the web, but I now need to enable access to my SQL Managed Instance. My App is in the same RG, region and VNet as my SQL Managed Instance. My VMs can access SQL MI without issue, but I cannot get VNet Integration working with my App. I've tried add a new VNet Integration, but when I select my Vnet, it says "This virtual network has no gateway". I'm trying to use Regional VNet integration, as all resources are in Central US. I've moved from Standard to P1V2 in an effort to fix this, (having read that this may be the issue) but no good! Oddly, I did manage to create one, but I removed it while troubleshooting connection issues. Now I can't recreate it! Do you have any ideas? Thanks very much :)

Or a more fundamental one? Does the Router Server change this limitation somehow? Can I install ARS in the ingrated VNET? Keep up the good work, please!

Hey John, Thanks for this video. Could you comment on the use of Deployment Slots along with Private Endpoint? Keeping your theme of running an Application in APP services where the desired state is keeping things connected privately. What techniques are available to keep deployment slots of an App Service App private as well?

@NTFAQGuy 3 года назад

At this point there is no deployment support for private endpoints but I think its in the works.

@amglover4361 3 года назад

Great video, as I've come to expect :-) Can I pick your brains on the use of two of these features at the same time? I have a web app which needs outbound connectivity to an on-premises database (tcp1433) over an ExpressRoute. The inbound (client) connections come from the Internet (not from on-prem nor from within Azure) and I want to place a WAG/WAF in front of the web app to give me layer 7 protection. Do I have to use an ASE for the web app or can I use 'regional vnet integration' for the database connection at the same time as using the WAG/WAF for the inbound connections? Thanks

@NTFAQGuy 3 года назад

you could use app service. yes regional vnet integration to get via expressroute then could use app gateway with service endpoints/private endpoints for the webapp.

@steveeyler 3 года назад

Another excellent video. Thus far I've spent over a week with Azure support trying to get Vnet integration into a spoke VNET to access resources on prem. Spoke is peered with a hub VNET that has the VNG with site to site tunnel to on prem. Agonizing that I can't get an answer what's missing to get this working.

@NTFAQGuy 3 года назад

Hi John, Really you presented great stuff to learn. I have one question, usually when we run web apps in Azure PaaS Solutions, we dont configure the Azure Load balancer. in the Azure load balancer we can add only the VM Ip address to the backend pool. Can you please shred some light on it how we can use load balacer in case of Azure WebApp running in PaaS environment

@NTFAQGuy 3 года назад

azure web app already has a load balancer, the front end is native to the service that balances to the back end instances. Now you can add something like app gateway if want additional layer 7 functionality.

@audiolibrary1653 2 года назад

Hello, on your video you told an app running on a vmnet integration subnet can't see the peered networks, we tested this in a PoC and works fine for an app to connect for example from a vmnet integration to an database in another vmnet with peering, this for your feedback.

@NTFAQGuy 2 года назад

Thanks yes there were updates. I thought I mentioned in another comment.

@jaggedll2 2 года назад

Hello John, as always illuminating. To expose an app service to the internet via a Firewall/WAF using a hub & spoke architecture, it seems the best option is a private endpoint for the app. Any comment?

@NTFAQGuy 2 года назад

that would work yes or use app gateway for example

@krynn1 3 года назад

Do you recommend using endpoints for azure sql dB for app service? Was trying to turn off sql public access

@NTFAQGuy 3 года назад

If you use service endpoint to a vnet it’s still locked down and takes optimized route but to completely remove use of public ip can use private endpoint.

@felipeccardoso 3 года назад

If you use vnet integration with VPN Gateway (Point-To-Site) or just VNET Integration Regional, and you want to restrict App Service connections on the on-premises firewall, what will be the outgoing IPs of the App Server for each of these cases?

@NTFAQGuy 3 года назад

outgoing ips from the app service would be the IPs it creates in the subnet its integrates with. if its P2S its the IP its given as part of the VPN.

@steveeyler 3 года назад

Haven't seen anything thus far that explains if you need to use two gateways when using gateway required and are intent on creating a S2S vpn to on prem. Is a second gateway required for App service P2S?

@NTFAQGuy 3 года назад

you can't have more than one gateway in a vnet.

@1979benmitchell 3 года назад

The only time I ever recommend using the ASE is when you need to have a dedicated Outbound IP for whitelisting. I wish you had the option of using a Public IP Prefix vs a single Outbound IP, as SNAT exhaustion is a real concern in large shared ASE Environments where you try to pack as much in as you can to avoid that hefty ASE Tax :)..

@NTFAQGuy 3 года назад

Nice!

@KelvinGalabuzi 3 года назад

And if you use a NAT Gateway, Integrate it to a VNet and associate that VNet with an App Service Plan.

@1979benmitchell 3 года назад

@@KelvinGalabuzi NAT Gateway is not an option for ASEv1 or ASEv2 as it is based on the older Cloud Services Tech Stack vs Azure App Services, even though it is called App Service Environment ( Only you Microsoft :D ). Because of this underlying technology, it is also limited to the older Basic SKU ALB, and scaling it is super slow compared to App Services (though part of that is also the dedicated nature of this deployment). What I've not tried is if you can use NAT Gateway with App Services? Have you successfully done that? ASEv1 and ASEv2 are also the only technology stacks for PaaS that Azure lists for PCI Compliance (specifically the ILB ASE) in their blueprints. I'm not sure if we could get normal App Services validated for PCI being a "shared" architecture. But if the NAT Gateway works with AppServices for Outbound IPs, then I'd be interested in mocking something up and seeing if I can't get it blessed by MSFT and our Auditors.

@hurrdurr4828 2 года назад

Hi John. At 4:25 you are stating that it technically go thru the public.. Is basically Microsoft using some managed NAT to understand vnets rfc 1918 behind the scenes? Even tho documentation is saying it goes on the backbone.. interesting detail.

@NTFAQGuy 2 года назад

Don’t know what I said at 4:25 but if it’s public ip then azure fabric basically NATs for private ip space of vnet. Does not have to be rfc1918

@steveeyler 3 года назад

Can the VNET subnet be an RFC 1918 address space? Also, what are the "workers" you are referring to? Thanks.

@NTFAQGuy 3 года назад

absolutely vnets are commonly 1918. workers are nodes that host the workloads like workers in AKS or nodes in app service plan
