Background:
I am hosting a static web app, generated by NUXTJS on an Azure App Service.
Now I want to configure something more by the web.config like set CORS setting for multiple domains.
But I cannot find any document to figure out what kind of web server has been integrated/installed within the azure app service.
Questions:
Maybe an IIS if the platform is Window based, otherwise Apache when creating AAS in Linux based. Is it correct?
And what is the corresponding version for each?
There are different HTTP server approaches in App Service for Windows and App Service for Linux.
Azure App Service for Windows runs on IIS with the use of modules.
.NET Core apps in App Service on Windows are hosted by ASP.NET Core module
Node.js apps in App Service on Windows are hosted with IISNode.
The IISNode project provides a native IIS 7/8 module that allows hosting of node.js applications in IIS 7/8 and IIS 7/8 Express.
Python 2.7 and Python 3.4 is by default is installed on App Service in root folders on the server
Java apps in App Service on Windows are hosted with Maven plugin
Azure App Service for Linux works a bit differently.

App Service for Linux comes with a bunch of preconfigured containers such as Node, PHP, Java, Python, Ruby and .NET Core.

I have an existing Windows Web App in Azure which I want to migrate to a Linux (docker) Web App. It is easy to setup a new Linux Web App with a new URI and that all works. However, I need to preserve the existing URI (myservice.azurewebsites.net) that I have on the Windows Web App and use it in the Linux Web App.
Any downtime is not acceptable, so I cannot just "test" if I can remove the current Windows Web App and "re-use" the same URI.
Created ASP.Net Core Web App and deployed to Azure Windows App Service.
Tried to deploy the same Web App to Linux App Service(Docker), got the below warning.
Tried to continue the steps to provide the configuration access to docker container, got the below error.
For the apps which we want to deploy in Azure Linux Docker, we need to Enable Docker and provide Docker OS , which is not required for Azure Windows App Service.
remove the current Windows Web App and "re-use" the same URI.
It is suggested to create a new App Service Plan and deploy to Linux App (Docker).
I'm working on a app that is hosted in Azure.
The app is a web-app based on node.js/express.js.
Is it running on/in a IIS server since it is hosted in Azure?
My app does not use the iisnode package. But i wonder if it is inherently running on IIS since it is hosted in Azure?
Also: As i understand at the moment, IIS-express and express.js is two completely different environments for hosting web-servers.....?
Just according to your description, it seems that you were talking about hosting a node App based on express.js to Azure WebApp for Windows.
Yes for hosting Node.js app in IIS on Azure WebApp for Windows, you need to use iisnode (a native IIS module) to host node.js applications with the web.config file in IIS on Windows. For more details, you can refer to the wiki page iisnode wiki of GitHub repo Azure/iisnode to know what iisnode is, and to know how to host it with a web.config file in IIS via the other wiki page Using a custom web.config for Node apps of GitHub repo projectkudu/kudu.
However, No for Azure WebApp for Windows, because you also can use IIS as a reverse proxy server to handle a Node app via the default port %HTTP_PLATFORM_PORT% specified by Azure WebApp like the blog Running java jar file to serve web requests on Azure App Service Web Apps for Java said. But generally, it's not a recommended way.
Meanwhile, No for hosting Node app on other Azure services, such as Azure WebApp for Liunx, Azure VM, or Azure Container services, these services based on Linux do not require IIS, so the iisnode module also be not absolute required.
If I need to host a web app in azure cloud, do I need to install windows server and iis in a VM or is there any other option like the web service running separately?
I have read azure app service while googled, if it's been used, Will it serve all the purpose of an iis?
In most scenarios you do not have to host a VM with IIS to host a web app in Azure. You can, but unless you want or need to manually manage a VM because you for instance need to install software on the server, there are simpler hosting alternatives.
Have a look at Azure App Service
Azure App Service is a service for hosting web applications, REST APIs, and mobile back ends. You can develop in your favorite language, be it .NET, .NET Core, Java, Ruby, Node.js, PHP, or Python. Applications run and scale with ease on both Windows and Linux-based environments.
EDIT:
As far as monitoring goes: there is a lot available to monitor the performance of an App Service. For instance:
Application Insights
Monitor apps in Azure App Service
EDIT2:
Will it serve all the purpose of an iis?
Are you looking for a specific purpose? Azure App Service brings you a LOT of possibilities. Sure, it's PaaS and therefore you're bound by the options available for the specific service. But you're also getting a lot of extra's IIS doesn't provide (out of the box). And when you're running a website that doesn't require you to install any COM stuff or something specific like that, there's nothing App Service doesn't provide.
I am creating app which uses Identity 2.1.0 framework in .NET. I started project in Visual Studio 2015 as Empty Web App (template). Now, I use Microsoft.AspNet.WebApi.Owin, and also Microsoft.Owin.Host.SystemWeb NuGet packages in my project. I understand that OWIN is a specification made to avoid monolithic frameworks and to specify how smaller application components interact with servers. However, I have requirement to deploy to Azure App Services.
I have found examples (blogs) where people deploy OWIN Web Api app as self-hosted to the Azure Cloud Services worker role. But I don't want this, as I don't use Cloud Service.
Since I am using Microsoft.Owin.Host.SystemWeb, am I going to be able to deploy this to Azure App service (which I assume manages internal IIS instance) ?
.NET ecosystem newbie here - so please excuse me for any possible redundancies in the question.
Microsoft.Owin.Host.SystemWeb is designed for hosting in IIS and all Azure App Service web apps are hosted in IIS, so this is exactly what you want (In fact, self-hosting likely won't work with Azure App Service).
I have InstallShield (IS) Basic MSI project, that creates Application Pool and installs web application on IIS under existing website.
On IIS default website is stopped and different website named WebApps using port 80 is running it uses AppPool1. Under WebApps we have several applications that use different App Pool for themselves for example AppPool2, AppPool3. When I install new application under WebApps and set its App Pool to newly created AppPool4 some applications App Pool changes to ASP.NET v4.0 AppPool1.
You can see my Application Pool and Web App settings below from IS.
Does anyone know why this could be happening?
Issue was with Web App .NET Framework version was set to v4.0 and this would cause all the Web Apps under Website to be set to use .NET Framework v4.0
