如何在ILB ASE中将Web应用程序保持为api app调用

Question

I have web and api app deployed within ILB ASE fronted by Application Gateway.Would I be able to make the calls from my web app to api app without exposing api app externally? If so, how can I do that?

I configured application gateway to point to the front end web app. I created internet routable domain and added to custom domain in my web app. In my DNS, I pointed the custom domain to hostname of the application gateway and I am able to logon to my web app. But, I see my web app written in AngualarJS is making XMLHttpRequest to backend API URL and as the backend API URL can not be resolved from my desktop, it is failing.

My requirement is not to expose API app outside of the ILB ASE VNET. Any suggestions?

If you want the web app and API could communicate with each other in an ILB ASE, you need to deploy an internal DNS service. For example, you could deploy a custom DNS server on Azure VM in the same Azure VNet. You can specify DNS server IP addresses in the VNet settings . The VNet is your ASE subnet located.

Please note that restart ASE after DNS IP address is added to VNet if you add the DNS after you deploy ASE. You could refer to this and read more details about custom DNS in ASE . Let me know if this works.
