Sometimes if you are using IIS in large-scale scenarios, meaning that if you are deploying an application within IIS service and you are expecting a large number of users to use this application, you can sometimes find some problems, meaning that the service can shut down by itself unexpectedly if you don't configure your IIS with the correct configuration that can handle this number of users.

It should be more user-friendly because unless you know how IIS works as a Microsoft product, a system admin cannot just manage it.
