I just created a sample api project and ran it inside of a container using docker commands and even created a custom image of the sample app. I am a beginner and am a bit confused right now as how is my app running inside of a container that contains just the runtime and dotnet specific images but no IIS. I used to think that Asp.net core web app requires a server and that could be either IIS or Kestrel but in my case I didn't have any of those. I ran my app in both Linux and Windows container. While in Linux container, I thought maybe behind the scenes Kestrel would be running but that shouldn't be the case in Windows container or maybe I am wrong all together.
So I just want to know how are the thing running in containers without a server? Also if possible can you please point me to articles explaining difference in performance as well
