The last thing we need to cover before we start building our Session Host are the Join Options. Now, there's basically three choices: Active Directory Join, which is the traditional approach to manning VMs in a Windows environment, Azure Active Directory Join, which would be a modern cloud management model, and in the middle, we have Hybrid Azure AD Join. This is where you would do a traditional Active Directory join and then you have group policies in place that will do a Azure Active Directory join on those same systems. 

Along with these join options, there's also different ways to manage. Traditionally, you would use group policy within Active Directory to control your environment. In the hybrid join environment, you can leverage group policy as well as modern management through Intune, also known as Microsoft Endpoint Manager. And on the Azure AD solution, we can only use Endpoint Manager. Now, since all three scenarios are viable and supported, the question you need to ask is, how do you want to manage?
