In this chapter, we looked at designing our supporting infrastructure components. These are elements that are necessary to support our XenApp deployment, including License Server, SQL databases, file services, and monitoring. We looked at the role and requirements, as well as recommended configurations, for each of these elements.

We took a deeper look at Director as well. Licensing, databases, and file services, although critical, tend to be a "one-time set it and forget routine" for most environments. Director, however, is designed to be used daily, as part of your operations.

Now that we have our primary site built and all the components configured, we can begin looking at optimizing our XenApp solution in the next chapter. This will include managing user profiles, configuring Citrix and Active Directory policies, and configuring printing. These will be the last steps we take to fine-tune our application before we are ready to begin production!
