In this chapter, we learned how to publish applications hosted on the Windows Server OS and manage virtual machine resource pools on the Delivery Controller to unlock the powerful features of Citrix XenApp. From the next chapter onwards, we will learn how to manage licensing, Group Policy, and profile management for this freshly built environment of XenApp machines. We will also learn how to optimize user experience and security based on the type of network that incoming connections are generated from. In other words, lots of interesting stuff is coming up shortly. Stay tuned!
