Within my App Service property in Azure I normally have an option to enable Web sockets. It seems that this option has been very recently removed. Is anyone able to advise if this is no longer supported or if I am doing something wrong?
Additional Information:
Azure App Plan is a B1
Enabling Web Socket has disappeared from App Service configuration
If you have hosted your Web App using Linux OS,
then as per this MS Doc)
Web Sockets are not currently supported for Linux apps on Free App Service Plans.
I have created another App Service with Windows OS with B1 Plan , I am able to see the option of Web Sockets in Configuration section
As MS said, you don't need to enable it because it's always enabled

Is it possible to remote-connect to an Azure App Service running on Windows with my IIS Manager?
This seems to have been possible according to this blog post by clicking in IIS Manager File -> Connect to a site.
I refer to the steps mentioned in the link shared by you and in the last step I got an error below.
I did some research on it and it looks like managing the App Service from IIS is not supported anymore. I have not got any official link but the below links might give you some information on it.
Microsoft.Web.Configuration.AppHostFileProvider not found after configured Remote IIS Administration for Microsoft Azure Web App
Can no longer manage any Web Apps with IIS Remote Manager - Could not load file or assembly - AppHostFileProvider
I'm not sure for what purpose why you want to. My thoughts is you shouldn't be doing that as it defeat the purpose of PaaS services. Cannot access the iis layer in app service however you can still configure in web.config of your web app.
I have deployed my react application on Azure App Service with .NET Stack (.NET Core 3.1,2.1). I have enabled Http2.0 from Azure App Service > Configuration > General Settings and also from azure resource explorer. At both places it shows Http2.0 but browser still uses Http1.1. TLS Settings are Https only and TLS version 1.2
There is no problem with this function.
I reproduced your problem. You only need to open a new privacy mode window and refresh it a few times to see the new settings take effect.
This problem may be caused by browser cache, etc.
Test Result.
In front of the APP service WAF was enabled. And WAF was not supporting Http2.0
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.
When setting up an App Service I can chose between App Service and App Service Linux.
The difference is that App Service runs on Windows Server and App Service Linux runs on Linux, but is there any practical difference?
Does it matter which one I pick?
There are some limitations for App Service on Linux. If you just want to have a web app service used only for development and testing purposes, you can select the free or shared tier of App Service on windows for a few cost. Or select the proper tier for your web app service depending on these features do you want.
Some features, such as virtual network integration, Azure Active
Directory/third-party authentication, or Kudu site extensions, are not
available yet. Once these features are available, we will update our
documentation and blog about the changes.
App Service on Linux is only supported with Basic, Standard, and
Premium app service plans and does not have a Free or Shared tier. You
cannot create Web App for Containers in an App Service plan already
hosting non-Linux Web Apps. There is a current limitation in regards
to not mixing Windows and Linux apps in the same resource group as
well.
I do not see the option to easily configure App Service Authentication on Web Apps for Linux. I am using SSL and custom domain name.
Thanks
If you are looking for an option through the Azure Portal, then this will help.
As per the Azure Web App on Linux documentation Limitations, The Azure portal shows only features that currently work for Web App on Linux and hides the rest. As Microsoft enable more features, they will be visible on the portal.
Some features, such as virtual network integration, Azure Active Directory/third-party authentication, or Kudu site extensions, are not available yet. Once these features are available, Microsoft will update the documentation and blog about the changes.
