Hosting multiple websites on your IIS server

Spinning up a web server, implementing the IIS role, and hosting a website are great first steps. Depending on the size and importance of your website, you may even require multiple web servers running that will serve up exact copies of the same website. You would then have a load balancer configured to send traffic between the multiple web servers. On the other hand, it's just as likely that your website will actually be an underutilization of your server's resources, rather than an overutilization, and so you have now created a new web server hosting a single website and it's really not being taxed at all. Is there a way that we can make use of that extra hardware that is currently sitting idle? Perhaps you have additional websites or web services that need to be turned on, for which you were planning to spin up multiple servers. The good news is that IIS can host many different websites at the same time. We can take that...
