In this hands-on lab, you reviewed some advanced Windows Azure service model features. You saw how to enable hosting a Web role in Internet Information Server (IIS) to access its full set of features. By enabling IIS, you were able to host multiple sites in a single Web role and create virtual applications and directories. Additionally, you explored start-up tasks that you can use to prepare the role environment, and how to use them to register a COM component, as well as installing entire binary file sets for a scripting language.
