I have created an Azure App Service inside an Internal App Service Environment. I want to make API App publicly available using Application Gateway.
Can anyone suggest me how to do it?

I'm facing issue with my multiple project solution in .net core webAPI. I've gatewayAPI which internally makes call to different microservices via http call.
Gateway API URI exposed to outer world which has domain as azure app name but the internal calls from gateway to microservices are configured with http://localhost:5001/{apiEndPoint} which is working fine in my local machine but after deploying it on azure app service I'm getting below error:
PostToServer call URL:'http://localhost:5001/api/authservice/authenticate' with Exception message An attempt was made to access a socket in a way forbidden by its access permissions. (localhost:5001).
Can someone please help me with this, I'm new to azure and learning on my own but could not find any solution for this yet.
PS: After going through some YouTube videos and blogs I got to know we have to use AKS but I'm not confident in that.
Would really appreciate any help on this issue.
The Gateway API you deployed to azure app service, it doesn't support custom port usage for 5001. Azure App Service only supports port 80|443(HTTP|HTTPS).
If you must use multiple ports in your actual project, then it is recommended to check whether Azure Cloud Service meets your needs. But it not the best choice.
The Best Practice:
Microservices architecture design
In short,create a Azure Gateway service, and your other microservice can be deployed in any where.(azure app service, vm or aks)
You just make sure you can access your microservices in your internal or public network environment.
If you're just learning, or the app isn't actually used by a lot of users, you can try the following suggestions:
Use SignalR (not azure signalr) to replace the websocket in your current project.
You have on azure app service, you can deploy your Gateway API Application to app service, and your other microservices can be deployed to Virtual Application in azure app service.
I have deployed few .net core microservices along with ocelot api gateway and react application using azure app services.
Every app service is running in its own app service plan and subnet with vnet integration enabled. I am able to restrict direct access to microservices through service end points.
The problem is, I want to restrict access to api gateway app service so that it only accepts traffic from react application app service. Whenever I try to do so through vnet integration and service endpoints, my application stops working with 403 IP forbidden.
Is there any way I can achieve the desired result?
In a typical 3-Tier web app, you run web servers in public subnet, while app tier lives in private subnet. Is it possible to run similar architecture with Azure Web apps and Api apps?
I guess you can run Asp.NET Core Web App in Azure Web App and Deploy AspNet Core Web Api to Azure Api App, then make Api end point private so only Web app can talk to it? I see options like Google, Facebook et. as auth providers. Is that what you have to do to make API private?

If you want that level of isolation, one (although expensive) option is an App Service Environment (ASE). Link to docs: https://learn.microsoft.com/en-us/azure/app-service-web/app-service-app-service-environment-intro
App Service Environments are ideal for application workloads requiring:
Very high scale
Isolation and secure network access
The public environment where you deploy by default is public. Your endpoints will be accessible to anyone anywhere, and it is up to your app to do the filtering. This can be done, e.g. through static IP address security settings in Web.config. The problem with that is that even then you can't know for sure what IP address your front-end will use for communication. There are multiple possible addresses it may use for outbound traffic, and those are subject to possible change.
You can see an example of IP restrictions here: restricting IP security
Of course you should also have authentication set up on your API. Documentation links:
https://learn.microsoft.com/en-us/azure/app-service/app-service-authentication-overview
https://learn.microsoft.com/en-us/azure/app-service-api/app-service-api-authentication
In line with what #juunas said above and a slight variant is to introduce Azure API Management Gateway in between Azure web app and Azure Api app. In standard tier API Gateway the IP address is fixed and doesn't change and you can use the API Gateway address in Azure API App web.config to whitelist.
I have a .NET Web Api project with several REST endpoints that I only want accessed by resources from within an Azure virtual network I have created. Resources such as Azure Functions and Azure Web Roles will access these endpoints only. In other words, I do not want the endpoints publicly available.
So, I configured the Web Api application with my virtual network but apparently I also need to add the Web Api application to an Application Service Environment (which are quite costly from what I have read). To quote the Azure documentation:
VNET Integration gives your web app access to resources in your virtual network but does not grant private access to your web app from the virtual network.
Do I indeed need to use an Application Service Environment and just deal with the costs or is there another way I can achieve what I want?
I do not want the endpoints publicly available.
Until now, Azure web app only supports for using an internal load balancer with the app service environment feature. If you want to make your Web API can only be accessed internally. An app service environment is required.
If you don't want to move your Web API to app service environment and your Azure function and web role have fixed ip addresses, you could configure the IP whitelist using ipSecurity configuration in your web API. For more information of ipSecurity, link below is for your reference.

Recently, I deployed a web application using Azure App Service. It's in the free tier service plan. I would like to access the logs of this web application and the IP address of the users who accessed my web application. How to find this information?
You'll need to enable Application Insights and use Web server telemetry
