IIS–websites versus app pools
A lot of people tend to use these interchangeably. From IIS’s perspective, a website is nothing more than a physical folder (and possibly virtual directories as well). That is – Websites – are storage as far as IIS is concerned. No CPU bound executable, no memory usage. Just plain folders and (virtual) directories.
An Application Pool is where all the action occurs. It constitutes the executable code that are part of your ASP.NET application. So – app pools are less about storage – and all about CPU and memory.
